Abstract
FK506 binding proteins (FKBPs) are a highly-conserved group of proteins known to bind to FK506, an immunosuppressive drug. They play different physiological roles, including transcription regulation, protein folding, signal transduction and immunosuppression. A number of FKBP genes have been identified in eukaryotes; however, very little information about these genes has been reported in Locusta migratoria. Here, we identified and characterized 10 FKBP genes from L. migratoria. Phylogenetic analysis and comparison of domain architectures indicated that the LmFKBP family can be divided into two subfamilies and five subclasses. Developmental and tissue expression pattern analysis revealed that all LmFKBPs transcripts, including LmFKBP46, LmFKBP12, LmFKBP47, LmFKBP79, LmFKBP16, LmFKBP24, LmFKBP44b, LmFKBP53, were periodically expressed during different developmental stages and mainly expressed in the fat body, hemolymph, testis, and ovary. In brief, our work depicts a outline but panoramic picture of LmFKBP family in L. migratoria, and provides a solid foundation to further investigate the molecular functions of LmFKBPs.

Abstract
It is well documented that the CO/NF-YB/NF-YC trimer (NF-Y-CO) binds and regulates the FT promoter. However, the FT/TFL1-like (FLOWERING LOCUS T/TERMINALFLOWER1-like) genes in gymnosperms are all flowering suppressors, and the regulation model of NF-Y in gymnosperms is different from that in angiosperms. Here, using Chinese pine (Pinus tabuliformis), we identified a CONSTANS-LIKE gene, PtCOL5, the expression of which was strongly induced during cones development and it functioned as a repressor of flowering. PtNF-YC4, which interacted with PtCOL5, was highly correlated with PtCOL5 during growth and development, has been demonstrated. Moreover, PtNF-YC4 and PtCOL5 can bind to PtTFL2 promoter, and their interaction can enhance PtTFL2 expression. Interestingly, we found PtNF-YC4 and PtCOL5 were involved in gibberellin signaling and their interaction was inhibited by PtDELLA protein, thus affecting PtTFL2 expression. Collectively, PtCOL5-PtNF-YC4 was involved in reproductive cone development and gibberellin signaling in Chinese pine. Our findings uncovered reproductive cone development and signal transduction mechanism of COL-NF-Y in gymnosperms.

Abstract
Alkaline stress severely limits plant growth and yield worldwide. NF-YC transcription factors (TFs) respond to abiotic stress by activating gene expression. However, the biological function of NF-YC TFs in alfalfa (Medicago sativa L.) is not clear. In our study, an NF-YC2 gene was identified and transgenic plants were obtained by constructing overexpression vector and cotyledon node transformation system in alfalfa. The open reading frame of MsNF-YC2 is 879 bp with 32.4 kDa molecular mass. MsNF-YC2 showed tissue expression specificity and was induced by a variety of abiotic stresses including drought, salt, and alkali stress in alfalfa. Under alkali stress treatment, transgenic plants exhibited higher levels of antioxidant enzyme activities and proline (Pro), correlating with a lower levels of hydrogen peroxide (H2O2), superoxide anion (O2 -) compared with wild-type (WT) plants. Transcriptomic results showed that overexpression of MsNF-YC2 regulated the expression of phytohormone signal transduction and photosynthesis-related genes under normal and alkaline stress treatments. These results suggest that the MsNF-YC2 gene plays crucial role enhance alkali adaptation abilities in alfalfa.

Abstract
It is known that nuclear factor Y (NF-Y) transcription factors play an important role in flowering time regulation and hormone response (ABA, GA) in angiosperms, but, little known in conifers. Moreover, the NF-Y gene family has not been comprehensively reported in conifers. Here, we identified 9 NF-YA, 9 NF-YB and 10 NF-YC genes in Pinus tabuliformis using Arabidopsis NF-Y protein sequences as queries. Additionally, by comparing conserved regions and phylogenetic relationships of the PtNF-Ys, we found that NF-Ys were both conserved and altered during evolution. PtTFL2, PtCO, PtNF-YC1 and PtNF-YC4 were exploited by expression profile in male cone development and correlation analysis. Furthermore, NF-YC1/4 and DPL (DELLA protein of P. tabuliformis) were interacted by yeast two-hybrid and BiFC assays, which suggested that NF-YC1/4 may be involved in gibberellins signaling pathway. Moreover, the multiple types of phytohormones-responsive cis-elements (ABA, JA, IAA, SA) have been found, and gene expression profile analysis showed that many NF-Y genes responded positively to SA and as opposed to IAA and JA, revealing the potential role of NF-Ys in conifers resistance. In summary, this study provided the basis for further investigation of the function of NF-Y genes in conifers.

Abstract
Flowering time is a key process in plant development. Photoperiodic signals play a crucial role in the floral transition in Arabidopsis thaliana, and the protein CONSTANS (CO) has a central regulatory function that is tightly regulated at the transcriptional and post-translational levels. The stability of CO protein depends on a light-driven proteasome process that optimizes its accumulation in the evening to promote the production of the florigen FLOWERING LOCUS T (FT) and induce seasonal flowering. To further investigate the post-translational regulation of CO protein we have dissected its interactome network employing in vivo and in vitro assays and molecular genetics approaches. The immunophilin FKBP12 has been identified in Arabidopsis as a CO interactor that regulates its accumulation and activity. FKBP12 and CO interact through the CCT domain, affecting the stability and function of CO. fkbp12 insertion mutants show a delay in flowering time, while FKBP12 overexpression accelerates flowering, and these phenotypes can be directly related to a change in accumulation of FT protein. The interaction is conserved between the Chlamydomonas algal orthologs CrCO-CrFKBP12, revealing an ancient regulatory step in photoperiod regulation of plant development.

Abstract
BACKGROUND AND AIMS The nuclear factor Y (NF-Y) transcription factor complex is important in plant growth, development and stress response. Information regarding this transcription factor complex is limited in cassava (Manihot esculenta). In this study, 15 MeNF-YAs, 21 MeNF-YBs and 15 MeNF-YCs were comprehensively characterized during plant defence. METHODS Gene expression in MeNF-Ys was examined during interaction with the bacterial pathogen Xanthomonas axonopodis pv. manihotis (Xam). The yeast two-hybrid system was employed to investigate protein-protein interactions in the heterotrimeric NF-Y transcription factor complex. The in vivo roles of MeNF-Ys were revealed by virus-induced gene silencing (VIGS) in cassava. KEY RESULTS The regulation of MeNF-Ys in response to Xam indicated their possible roles in response to cassava bacterial blight. Protein-protein interaction assays identified the heterotrimeric NF-Y transcription factor complex (MeNF-YA1/3, MeNF-YB11/16 and MeNF-YC11/12). Moreover, the members of the heterotrimeric NF-Y transcription factor complex were located in the cell nucleus and conferred transcriptional activation activity to the CCAAT motif. Notably, the heterotrimeric NF-Y transcription factor complex positively regulated plant disease resistance to Xam, confirmed by a disease phenotype in overexpressing plants in Nicotiana benthamiana and VIGS in cassava. Consistently, the heterotrimeric NF-Y transcription factor complex positively regulated the expression of pathogenesis-related genes (MePRs). CONCLUSIONS The NF-Y transcription factor complex (MeNF-YA1/3, MeNF-YB11/16 and MeNF-YC11/12) characterized here was shown to play a role in transcriptional activation of MePR promoters, contributing to the plant defence response in cassava.

Abstract
Picea wilsonii transcription factor PwNAC2 enhanced plant tolerance to salt and drought stress through multiple signaling pathway and interacted with PwRFCP1 to participate in flowering regulation. NAC is one of the largest transcription factor families in plants, however, its role is not yet fully understood. Here, we identified a transcription factor PwNAC2 in Picea wilsonii, which localized in nucleus with transcriptional activity in C-terminal region and can form homodimer by itself. Expression analysis by real-time PCR showed that PwNAC2 was induced by multiple abiotic stresses and phytohormones stimuli. PwRFCP1 (Resemble-FCA-contain-PAT1 domain), an interaction protein of PwNAC2 was screened via yeast two hybrid. Luciferase complementation assay confirmed the interaction in vivo and bimolecular fluorescence complementation assay showed the interaction in nucleus. PwNAC2 overexpression retarded Arabidopsis hypocotyls growth which is closely related to light, whereas promotion of hypocotyls growth by PwRFCP1 is independent on light. Under drought or salt treatment, overexpression of PwNAC2 in Arabidopsis showed more vigorous seed germination and significant tolerance for seedlings by ROS scavenging, reducing of membrane damage, slower water loss and increased stomatal closure. ABA or CBF-pathway marker genes were substantially higher in PwNAC2 transgenic Arabidopsis. Overexpression of PwRFCP1 promotes flowering in transgenic Arabidopsis, whereas PwNAC2 delayed flowering by altering the expression of FT, SOC1 and FLC. In addtioin, PwRFCP1 overexpression plants showed no higher tolerance to stress treatment than Col-0. Collectively, our results indicate that PwNAC2 enhanced plant tolerance to abiotic stress through multiple signaling pathways and participated in PwRFCP1-regulated flowering time.

Abstract
Background The FK506-binding proteins (FKBPs) play diverse roles in numerous critical processes for plant growth, development, and abiotic stress responses. However, the FKBP gene family in the important fruit crop apple (Malus × domestica Borkh.) has not been studied as thoroughly as in other species. Our research objective was to investigate the mechanisms by which apple FKBPs enable apple plants to tolerate the effects of abiotic stresses. Results Using bioinformatics-based methods, RT-PCR, and qRT-PCR technologies, we identified 38 FKBP genes and cloned 16 of them in the apple genome. The phylogenetic analysis revealed three major groups within that family. The results from sequence alignments, 3-D structures, phylogenetics, and analyses of conserved domains indicated that apple FKBPs are highly and structurally conserved. Furthermore, genomics structure analysis showed that those genes are also highly and structurally conserved in several other species. Comprehensive qRT-PCR analysis found various expression patterns for MdFKBPs in different tissues and in plant responses to water-deficit and salt stresses. Based on the results from interaction network and co-expression analyses, we determined that the pairing in the MdFKBP62a/MdFKBP65a/b-mediated network is involved in water-deficit and salt-stress signaling, both of which are uniformly up-regulated through interactions with heat shock proteins in apple. Conclusions These results provide new insight for further study of FKBP genes and their functions in abiotic stress response and multiple metabolic and physiological processes in apple.

PaFKBP12 overexpression in Arabidopsis resulted in stress tolerance to heat, ABA, drought, and salt stress, in addition to growth promotion under normal conditions. Polytrichastrum alpinum (alpine haircap moss) is one of polar organisms that can withstand the severe conditions of the Antarctic. In this study, we report the isolation of a peptidyl prolyl isomerase FKBP12 gene (PaFKBP12) from P. alpinum collected in the Antarctic and its functional implications in development and stress responses in plants. In P. alpinum, PaFKBP12 expression was induced by heat and ABA. Overexpression of PaFKBP12 in Arabidopsis increased the plant size, which appeared to result from increased rates of cell cycle. Under heat stress conditions, PaFKBP12-overexpressing lines (PaFKBP12-OE) showed better growth and survival than the wild type. PaFKBP12-OE also showed higher root elongation rates, better shoot growth and enhanced survival at higher concentrations of ABA in comparison to the wild type. In addition, PaFKBP12-OE were more tolerant to drought and salt stress than the wild type. All these phenotypes were accompanied with higher induction of the stress responsive genes in PaFKBP12-OE than in the wild type. Taken together, our findings revealed important functions of PaFKBP12 in plant development and abiotic stress responses.

Abstract
Plant development and architecture are greatly influenced by the polar distribution of the essential hormone auxin. The directional influx and efflux of auxin from plant cells depends primarily on AUX1/LAX, PIN, and ABCB/PGP/MDR families of auxin transport proteins. The functional analysis of these proteins has progressed rapidly within the last decade thanks to the establishment of heterologous auxin transport systems. Heterologous co-expression allowed also for the testing of protein-protein interactions involved in the regulation of transporters and identified relationships with members of the FK506-Binding Protein (FKBP) and cyclophilin protein families, which are best known in non-plant systems as cellular receptors for the immunosuppressant drugs, FK506 and cyclosporin A, respectively. Current evidence that such interactions affect membrane trafficking, and potentially the activity of auxin transporters is reviewed. We also propose that FKBPs andcyclophilins might integrate the action of auxin transport inhibitors, such as NPA, on members of the ABCB and PIN family, respectively. Finally, we outline open questions that might be useful for further elucidation of the role of immunophilins as regulators (servants) of auxin transporters (masters).

Abstract
Heterotrimeric nuclear factors Y (NF-Ys) are involved in regulation of various vital functions in all eukaryotic organisms. Although a number of NF-Y subunits have been characterized in model plants, only a few have been functionally evaluated in crops. In this work, a number of genes encoding NF-YB and NF-YC subunits were isolated from drought-tolerant wheat (Triticum aestivum L. cv. RAC875), and the impact of the overexpression of TaNF-YB4 in the Australian wheat cultivar Gladius was investigated. TaNF-YB4 was isolated as a result of two consecutive yeast two-hybrid (Y2H) screens, where ZmNF-YB2a was used as a starting bait. A new NF-YC subunit, designated TaNF-YC15, was isolated in the first Y2H screen and used as bait in a second screen, which identified two wheat NF-YB subunits, TaNF-YB2 and TaNF-YB4. Three-dimensional modelling of a TaNF-YB2/TaNF-YC15 dimer revealed structural determinants that may underlie interaction selectivity. The TaNF-YB4 gene was placed under the control of the strong constitutive polyubiquitin promoter from maize and introduced into wheat by biolistic bombardment. The growth and yield components of several independent transgenic lines with up-regulated levels of TaNF-YB4 were evaluated under well-watered conditions (T1-T3 generations) and under mild drought (T2 generation). Analysis of T2 plants was performed in large deep containers in conditions close to field trials. Under optimal watering conditions, transgenic wheat plants produced significantly more spikes but other yield components did not change. This resulted in a 20-30% increased grain yield compared with untransformed control plants. Under water-limited conditions transgenic lines maintained parity in yield performance.

Abstract
Nuclear factor Y (NF-Y) is a highly conserved transcription factor comprising NF-YA, NF-YB and NF-YC subunits. To date, the roles of NF-Y subunit in plant still remain elusive. In this study, a subunit NF-YB (PwNF-YB3), was isolated from Picea wilsonii Mast. and its role was studied. PwNF-YB3 transcript was detected in all vegetative and reproductive tissues with higher levels in stem and root and was greatly induced by salinity, heat and PEG but not by cold and ABA treatment. Over-expression of PwNF-YB3 in Arabidopsis showed a significant acceleration in the onset of flowering and resulted in more vigorous seed germination and significant tolerance for seedlings under salinity, drought and osmotic stress compared with wild type plants. Transcription levels of salinity-responsive gene (SOS3) and drought-induced gene (CDPK1) were substantially higher in transgenic Arabidopsis than in wild-type plants. Importantly, CBF pathway markers (COR15B, KIN1, LEA76), but not ABA pathway markers CBF4, were greatly induced under condition of drought. The nuclear localization showed that NF-YB3 acted as a transcription factor. Taken together, the data provide evidence that PwNF-YB3 positively confers significant tolerance to salt, osmotic and drought stress in transformed Arabidopsis plants probably through modulating gene regulation in CBF-dependent pathway.

Abstract
Nuclear factor-Y (NF-Y), a heterotrimeric transcription factor, is composed of NF-YA, NF-YB and NF-YC proteins. In plants, there are usually more than 10 genes for each family and their members have been identified to be key regulators in many developmental and physiological processes controlling gametogenesis, embryogenesis, nodule development, seed development, abscisic acid (ABA) signaling, flowering time, primary root elongation, blue light responses, endoplasmic reticulum (ER) stress response and drought tolerance. Taking the advantages of the recent soybean genome draft and information on functional characterizations of nuclear factor Y (NF-Y) transcription factor family in plants, we identified 21 GmNF-YA, 32 GmNF-YB, and 15 GmNF-YC genes in the soybean (Glycine max) genome. Phylogenetic analyses show that soybean's proteins share strong homology to Arabidopsis and many of them are closely related to functionally characterized NF-Y in plants. Expression analysis in various tissues of flower, leaf, root, seeds of different developmental stages, root hairs under rhizobium inoculation, and drought-treated roots and leaves revealed that certain groups of soybean NF-Y are likely involved in specific developmental and stress responses. This study provides extensive evaluation of the soybean NF-Y family and is particularly useful for further functional characterization of GmNF-Y proteins in seed development, nodulation and drought adaptation of soybean.

Plant immunophilins: a review of their structure-function relationship. Biochim Biophys Acta Gen Subj 2014; 1850:2145-58.

Abstract
BACKGROUND Originally discovered as receptors for immunosuppressive drugs, immunophilins consist of two major groups, FK506 binding proteins (FKBPs) and cyclosporin A binding proteins (cyclophilins, CYPs). Many members in both FKBP and CYP families are peptidyl prolyl isomerases that are involved in protein folding processes, though they share little sequence homology. It is not surprising to find immunophilins in all organisms examined so far, including viruses, bacteria, fungi, plants and animals, as protein folding represents a common process in all living systems. SCOPE OF REVIEW Studies on plant immunophilins have revealed new functions beyond protein folding and new structural properties beyond that of typical PPIases. This review focuses on the structural and functional diversity of plant FKBPs and CYPs. MAJOR CONCLUSIONS The differences in sequence, structure as well as subcellular localization, have added on to the diversity of this family of molecular chaperones. In particular, the large number of immunophilins present in the thylakoid lumen of the photosynthetic organelle, promises to deliver insights into the regulation of photosynthesis, a unique feature of plant systems. However, very little structural information and functional data are available for plant immunophilins. GENERAL SIGNIFICANCE Studies on the structure and function of plant immunophilins are important in understanding their role in plant biology. By reviewing the structural and functional properties of some immunophilins that represent the emerging area of research in plant biology, we hope to increase the interest of researchers in pursuing further research in this area.

Abstract
Several eukaryotic Heme-associated proteins (HAPs) have been reported to bind specifically to DNA fragments containing CCAAT-box; however, the physiological functions and direct targets of these HAP proteins in plants remain unclear. In this study, we showed that AtHAP5A as a transcription factor interacted with CCAAT motif in vivo, and AtXTH21, one direct target of AtHAP5A, was involved in freezing stress resistance. The AtHAP5A overexpressing plants were more tolerant, whereas the loss-of-function mutant of AtHAP5A was more sensitive to freezing stress than wild-type plants. Chromatin immunoprecipitation (ChIP) assay demonstrated that AtHAP5A could bind to five fragments that contained CCAAT motifs in the AtXTH21 promoter. Similarly, the AtXTH21 overexpressing plants exhibited improved freezing resistance, while xth21 knockdown mutants displayed decreased freezing resistance. Notably, the modulated freezing resistance of AtHAP5A overexpressing plants and knockout mutant could be reversed by the xth21 mutant and AtXTH21 overexpressing plants, respectively, indicating that AtHAP5A might act upstream of AtXTH21 in freezing stress. Additionally, modulation of AtHAP5A and AtXTH21 expression had the same effects on abscisic acid (ABA) sensitivity and reactive oxygen species (ROS) metabolism. Taken together, these results demonstrated that AtHAP5A modulates freezing stress resistance in Arabidopsis through binding to the CCAAT motif of AtXTH21.

Abstract
NF-Y is a conserved oligomeric transcription factor found in all eukaryotes. In plants, this regulator evolved with a broad diversification of the genes coding for its three subunits (NF-YA, NF-YB and NF-YC). The NF-YB members can be divided into Leafy Cotyledon1 (LEC1) and non-LEC1 types. Here we presented a comparative genomic study using phylogenetic analyses to validate an evolutionary model for the origin of LEC-type genes in plants and their emergence from non-LEC1-type genes. We identified LEC1-type members in all vascular plant genomes, but not in amoebozoa, algae, fungi, metazoa and non-vascular plant representatives, which present exclusively non-LEC1-type genes as constituents of their NF-YB subunits. The non-synonymous to synonymous nucleotide substitution rates (Ka/Ks) between LEC1 and non-LEC1-type genes indicate the presence of positive selection acting on LEC1-type members to the fixation of LEC1-specific amino acid residues. The phylogenetic analyses demonstrated that plant LEC1-type genes are evolutionary divergent from the non-LEC1-type genes of plants, fungi, amoebozoa, algae and animals. Our results point to a scenario in which LEC1-type genes have originated in vascular plants after gene expansion in plants. We suggest that processes of neofunctionalization and/or subfunctionalization were responsible for the emergence of a versatile role for LEC1-type genes in vascular plants, especially in seed plants. LEC1-type genes besides being phylogenetic divergent also present different expression profile when compared with non-LEC1-type genes. Altogether, our data provide new insights about the LEC1 and non-LEC1 evolutionary relationship during the vascular plant evolution.

Abstract
NF-Y (NUCLEAR FACTOR-Y), a heterotrimeric transcription factor, is composed of NF-YA, NF-YB, and NF-YC proteins in yeast, animal, and plant systems. In plants, each of the NF-YA/B/C subunit forms a multi-member family. NF-Ys are key regulators with important roles in many physiological processes, such as drought tolerance, flowering time, and seed development. In this study, we identified, annotated, and further characterized 14 NF-YA, 14 NF-YB, and 5 NF-YC proteins in Brassica napus (canola). Phylogenetic analysis revealed that the NF-YA/B/C subunits were more closely clustered with the Arabidopsis thaliana (Arabidopsis) homologs than with rice OsHAP2/3/5 subunits. Analyses of the conserved domain indicated that the BnNF-YA/B/C subfamilies, respectively, shared the same conserved domains with those in other organisms, including Homo sapiens, Saccharomyces cerevisiae, Arabidopsis, and Oryza sativa (rice). An examination of exon/intron structures revealed that most gene structures of BnNF-Y were similar to their homologs in Arabidopsis, a model dicot plant, but different from those in the model monocot plant rice, suggesting that plant NF-Ys diverged before monocot and dicot plants differentiated. Spatial-tempo expression patterns, as determined by qRT-PCR, showed that most BnNF-Ys were widely expressed in different tissues throughout the canola life cycle and that several closely related BnNF-Y subunits had similar expression profiles. Based on these findings, we predict that BnNF-Y proteins have functions that are conserved in the homologous proteins in other plants. This study provides the first extensive evaluation of the BnNF-Y family, and provides a useful foundation for dissecting the functions of BnNF-Y.

Abstract
The FK506 binding proteins (FKBPs) are abundant and ubiquitous proteins belonging to the large peptidyl-prolylcis-trans isomerase superfamily. FKBPs are known to be involved in many biological processes including hormone signaling, plant growth, and stress responses through a chaperone or an isomerization of proline residues during protein folding. The availability of complete strawberry genome sequences allowed the identification of 23 FKBP genes by HMMER and blast analysis. Chromosome scaffold locations of these FKBP genes in the strawberry genome were determined and the protein domain and motif organization of FaFKBPs analyzed. The phylogenetic relationships between strawberry FKBPs were also assessed. The expression profiles of FaFKBPs genes results revealed that most FaFKBPs were expressed in all tissues, while a few FaFKBPs were specifically expressed in some of the tissues. These data not only contribute to some better understanding of the complex regulation of the strawberry FKBP gene family, but also provide valuable information for further research in strawberry functional genomics.

Abstract
HAP is a ubiquitous transcription factor family which consists of three distinct subunits, namely HAP2, HAP3, and HAP5. Among them, HAP2 and HAP3 subunits have been reported to be involved in plant response to abiotic stress. Here, a HAP5 subunit was identified from Picea wilsonii Mast. and transformed to Arabidopsis to investigate its functions in plant stress response. We found that transformed Arabidopsis with over-expressing PwHAP5 exhibited higher seed germination under salinity, osmotic and abscisic acid (ABA) stress treatment compared to Col-0 plants. The seedlings of transformed Arabidopsis also showed improved tolerance to salinity and decreased sensitivity to ABA treatment. Over-expression of PwHAP5 in Arabidopsis athap5 mutant rescued partly tolerance to NaCl, mannitol and ABA treatment. Furthermore, we examined transcription levels of several stress-related genes in transformed seedlings. Among them, mRNA expression levels of COR15a, KIN1, DREB2A, and RD29A genes were substantially higher in transformed Arabidopsis than those in wild-type (Col-0) plants. Therefore, our data revealed that PwHAP5 plays positive roles in response to salinity, osmotic and ABA stress at different developmental stages in plants, respectively, via possibly regulating stress-related genes.

Abstract
Wheat scab, caused by the fungal pathogen Fusarium graminearum is a devastating disease worldwide. Despite an extensive and coordinated effort to investigate this pathosystem, little progress has been made to understand the molecular basis of host-pathogen interactions, for example how the pathogen causes disease in plant. Recently, a secreted lipase (FGL1) has been identified from the fungus and shown to be an important virulence factor; however, the intrinsic function of FGL1 in plant is unknown. Here, we report the identification of the molecular components that may possibly be involved in the FGL virulence pathway using yeast two hybrid system. FGL gene was amplified from a local virulent strain (F15) and shown to be 99.5% identical to the original published FGL at the amino acid level. We showed that transient expression of this FGL gene by Agroinfiltration in tobacco leaves causes cell death further implicating the role of FGL in virulence. To identify FGL initial physical target in plant, we screened two wheat cDNA libraries using the FGL protein as the bait. From both libraries, a small FKBP-type immunophilin protein, designated wFKBP12, was found to physically interact with FGL. The direct interaction of FGL with wFKBP12 was confirmed in living onion epidermal cells by biomolecular fluorescence complementation (BiFC) assay. To investigate further, we then used wFKBP12 protein as bait and identified an elicitor-responsive protein that contains a potential Ca(2+) binding domain. Semi-quantitative PCR showed that this elicitor-responsive gene is down-regulated during the F. graminearum infection suggesting that this protein may be an important component in FGL virulence pathway. This work serves as an initial step to reveal how fungal lipases act as a general virulence factor.

Abstract
Transcription factors belonging to the CCAAT-box binding factor family (also known as the Nuclear Factor Y) are present in all higher eukaryotes. Studies in plants have revealed that each subunit of this heterotrimeric transcription factor is encoded by a gene belonging to a multigene family allowing a considerable modularity. In this review, we focus on recent findings concerning the expression patterns and potential functions of different members of these NF-Y protein families using a phylogenetic approach. During the course of evolution plant CCAAT-box binding factors seem to have diversified into at least two main groups. The first group has more general expression patterns and/or functions whereas the second group has acquired more specific expression patterns and/or functions and could play key roles in specific pathways.

Abstract
The CCAAT box is one of the most common cis-elements present in eukaryotic promoters and is bound by the transcription factor NUCLEAR FACTOR Y (NF-Y). NF-Y is composed of three subunits, NF-YA, NF-YB, and NF-YC. Unlike animals and fungi, plants have significantly expanded the number of genes encoding NF-Y subunits. We provide a comprehensive classification of NF-Y genes, with a separation of closely related, but distinct, histone fold domain proteins. We additionally review recent experiments that have placed NF-Y at the center of many developmental stress-responsive processes in the plant lineage.

Abstract
The FK506-binding proteins (FKBPs) are known both as the receptors for immunosuppressant drugs and as prolyl isomerase (PPIase) enzymes that catalyse rotation of prolyl bonds. FKBPs are characterised by the inclusion of at least one FK506-binding domain (FKBd), the receptor site for proline and the active site for PPIase catalysis. The FKBPs form large and diverse families in most organisms, with the largest FKBP families occurring in higher plants. Plant FKBPs are molecular chaperones that interact with specific protein partners to regulate a diversity of cellular processes. Recent studies have found that plant FKBPs operate in intricate and coordinated mechanisms for regulating stress response and development processes, and discoveries of new interaction partners expand their cellular influences to gene expression and photosynthetic adaptations. This review presents an examination of the molecular and structural features and functional roles of the higher plant FKBP family within the context of these recent findings, and discusses the significance of domain conservation and variation for the development of a diverse, versatile and complex chaperone family.

Abstract
The FK506-binding proteins (FKBPs) belong to the peptidyl-prolyl cis/trans isomerase (PPIase) superfamily, and have been implicated in a wide spectrum of biological processes, including protein folding, hormone signaling, plant growth, and stress responses. Genome-wide structural and evolutionary analyses of the entire FKBP gene family have been conducted in Arabidopsis and rice. In the present study, a genome-wide analysis was performed to identify all maize FKBP genes. The availability of complete maize genome sequences allowed for the identification of 24 FKBP genes. Chromosomal locations in the maize genome were determined and the protein domain and motif organization of ZmFKBPs analyzed. The phylogenetic relationships between maize FKBPs were also assessed. The expression profiles of ZmFKBP genes were measured under different environmental conditions and revealed distinct ZmFKBP gene expression patterns under heat, cold, salt, and drought stress. These data not only contribute to a better understanding of the complex regulation of the maize FKBP gene family, but also provide evidence supporting the role of FKBPs in multiple signaling pathways involved in stress responses. This investigation may provide valuable information for further research on stress tolerance in plants and potential strategies for enhancing maize survival under stressful conditions.
