Abstract
UVB significantly impacts the occurrence of cutaneous disorders, ranging from inflammatory to neoplastic diseases. Polyphenols derived from plants have been found to exhibit photoprotective effects against various factors that contribute to skin cancer. During the fermentation of the polyphenol-enriched blueberry preparation (PEBP), small oligomers of polyphenols were released, thus enhancing their photoprotective effects. This study aimed to investigate the protective effects of PEBP on UVB-induced skin inflammation. Topical preparations of polyphenols were applied to the skin of dorsally shaved mice. Mice were subsequently exposed to UVB and were sacrificed 90 min after UVB exposure. This study revealed that pretreatment with PEBP significantly inhibited UVB-induced recruitment of mast and neutrophil cells and prevented the loss of skin thickness. Furthermore, the findings show that PEBP treatment resulted in the downregulation of miR-210, 146a, and 155 and the upregulation of miR-200c and miR-205 compared to the UVB-irradiated mice. Additionally, PEBP was found to reduce the expression of IL-6, IL-1β, and TNFα, inhibiting COX-2 and increasing IL-10 after UVB exposure. Moreover, DNA methylation analysis indicated that PEBP might potentially reduce the activation of inflammation-related pathways such as MAPK, Wnt, Notch, and PI3K-AKT signaling. Our finding suggests that topical application of PEBP treatment may effectively prevent UVB-induced skin damage by inhibiting inflammation.

Abstract
Phosphatidylethanolamine binding protein (PEBP) plays an important role in regulating flowering time and morphogenesis of plants. However, the identification and functional analysis of PEBP gene in pineapple (AcPEBP) have not been systematically studied. The pineapple genome contained 11 PEBP family members, which were subsequently classified into three subfamilies (FT-like, TFL-like and MFT-like) based on phylogenetic relationships. The arrangement of these 11 shows an unequal pattern across the six chromosomes of pineapple the pineapple genome. The anticipated outcomes of the promoter cis-acting elements indicate that the PEBP gene is subject to regulation by diverse light signals and endogenous hormones such as ethylene. The findings from transcriptome examination and quantitative real-time polymerase chain reaction (qRT-PCR) indicate that FT-like members AcFT3 and AcFT4 display a heightened expression level, specifically within the floral structures. The expression of AcFT3 and AcFT4 increases sharply and remains at a high level after 4 days of ethylene induction, while the expression of AcFT7 and AcMFT1 decreases gradually during the flowering process. Additionally, AcFT3, AcFT4 and AcFT7 show specific expression in different floral organs of pineapple. These outcomes imply that members belonging to the FT-like subfamily may have a significant impact on the process of bud differentiation and flower development. Through transcriptional activation analysis, it was determined that AcFT4 possesses transcriptional activation capability and is situated in the nucleus and peripheral cytoplasm. Overexpression of AcFT4 in Arabidopsis resulted in the promotion of early flowering by 6-7 days. The protein interaction prediction network identified potential flower regulators, including CO, AP1, LFY and SOC1, that may interact with PEBP proteins. This study explores flower development in pineapple, thereby serving as a valuable reference for future research endeavors in this domain.

Abstract
Phosphatidylethanolamine-binding protein (PEBP) is widely involved in various physiological behaviors, such as the transition from vegetative growth to reproductive growth in plants, tumorigenesis in the human, etc. However, few functional studies have examined pebp genes affecting the development of fungi. In this study, Capebp2 was cloned from Cyclocybe aegerita AC0007 strains based on the genome sequence and gene prediction, and the sequence alignment of CaPEBP2 with other PEBP proteins from other biological sources including plant, animal, fungi, and bacteria indicated that PEBP had low sequence similarity in fungi, whereas all protein sequences had some conserved motifs such as DPDAP and HRY. Expression analysis showed the transcription level of Capebp2 increased approximately 20-fold in fruiting bodies compared with mycelia. To uncover the function of Capebp2 in C. aegetita development, Capebp2 was cloned into a pATH vector driven by the actin promoter for obtaining overexpression transformant lines. Fruiting experiments showed the transformed strains overexpressing Capebp2 exhibited redifferentiation of the cap on their surface, including intact fruiting bodies or partial lamella during fruiting development stage, and the longitudinal section indicated that all regenerated bodies or lamella sprouted from the flesh and shared the epidermis with the mother fruiting bodies. In summary, the sequence characterization of Capebp2, expression level during different development stages, and function on fruiting body development were documented in this study, and these findings provided a reference to study the role of pebp in the development process of basidiomycetes. Importantly, gene mining of pebp, function characterization, and the regulating pathways involved need to be uncovered in further studies.

Abstract
KEY MESSAGE TFL1-like genes of the basal eudicot Platanus acerifolia have conserved roles in maintaining vegetative growth and inhibiting flowering, but may act through distinct regulatory mechanism. Three TERMINAL FLOWER 1 (TFL1)-like genes were isolated and characterized from London plane tree (Platanus acerifolia). All genes have conserved genomic organization and characteristic of the phosphatidylethanolamine-binding protein (PEBP) family. Sequence alignment and phylogenetic analysis indicated that two genes belong to the TFL1 clade, designated as PlacTFL1a and PlacTFL1b, while another one was grouped in the BFT clade, named as PlacBFT. qRT-PCR analysis showed that all three genes primarily expressed in vegetative phase, but the expression of PlacTFL1a was much higher and wider than that of PlacTFL1b, with the latter only detected at relatively low expression levels in apical and lateral buds in April. PlacBFT was mainly expressed in young stems of adult trees followed by juvenile tissues. Ectopic expression of any TFL1-like gene in Arabidopsis showed phenotypes of delayed or repressed flowering. Furthermore, overexpression of PlacTFL1a gene in petunia also resulted in extremely delayed flowering. In non-flowering 35:PlacTFL1a transgenic petunia plants, the FT-like gene (PhFT) gene was significantly upregulated and AP1 homologues PFG, FBP26 and FBP29 were significantly down-regulated in leaves. Yeast two-hybrid analysis indicated that only weak interactions were detected between PlacTFL1a and PlacFDL, and PlacTFL1a showed no interaction with PhFDL1/2. These results indicated that the TFL1-like genes of Platanus have conserved roles in repressing flowering, but probably via a distinct regulatory mechanism.

Abstract
BACKGROUND With the release of genomic data for B.rapa, B.oleracea, and B.napus, research on the genetic and molecular functions of Brassica spp. has entered a new stage. PEBP genes in plants play an important role in the transition to flowering as well as seed development and germination. Molecular evolutionary and functional analyses of the PEBP gene family in B.napus based on molecular biology methods can provide a theoretical basis for subsequent investigations of related regulators. RESULTS In this paper, we identified a total of 29 PEBP genes from B.napus that were located on 14 chromosomes and 3 random locations. Most members contained 4 exons and 3 introns; motif 1 and motif 2 were the characteristic motifs of PEBP members. On the basis of intraspecific and interspecific collinearity analyses, it is speculated that fragment replication and genomic replication are the main drivers of for the amplification and evolution of the PEBP gene in the B.napus genome. The results of promoter cis-elements prediction suggest that BnPEBP family genes are inducible promoters, which may directly or indirectly participate in multiple regulatory pathways of plant growth cycle. Furthermore, the tissue-specific expression results show that the expression levels of BnPEBP family genes in different tissues were quite different, but the gene expression organization and patterns of the same subgroup were basically the same. qRT‒PCR revealed certain spatiotemporal patterns in the expression of the PEBP subgroups in roots, stems, leaves, buds, and siliques, was tissue-specific, and related to function. CONCLUSIONS A systematic comparative analysis of the B.napus PEBP gene family was carried out at here. The results of gene identification, phylogenetic tree construction, structural analysis, gene duplication analysis, prediction of promoter cis-elements and interacting proteins, and expression analysis provide a reference for exploring the molecular mechanisms of BnPEBP family genes in future research.

Abstract
Tubers and tuberous root crops are essential carbohydrate sources and staple foods for humans, second only to cereals. The developmental phase transition, including floral initiation and underground storage organ formation, is controlled by complex signaling processes involving the integration of environmental and endogenous cues. FLOWERING LOCUS T (FT) and TERMINAL FLOWER 1/CENTRORADIALIS (TFL1/CEN), members of the phosphatidylethanolamine-binding protein (PEBP) gene family, play a central role in this developmental phase transition process. FT and FT-like proteins have a function to promote developmental phase transition, while TFL1/CEN act oppositely. The balance between FT and TFL1/CEN is critical to ensure a successful plant life cycle. Here, we present a summarized review of the role and signaling network of PEBP in floral initiation and underground storage organ formation, specifically in tubers and tuberous root crops. Lastly, we point out several questions that need to be answered in order to have a more complete understanding of the PEBP signaling network, which is crucial for the agronomical improvement of tubers and tuberous crops.

Abstract
Phosphatidyl ethanolamine-binding proteins (PEBPs) are involved in regulating flowering time and various developmental processes. Functions and expression patterns in cultivated peanuts (Arachis hypogaea L.) remain unknown. In this study, 33 PEBP genes in cultivated peanuts were identified and divided into four subgroups: FT, TFL, MFT and FT-like. Gene structure analysis showed that orthologs from A and B genomes in cultivated peanuts had highly similar structures, but some orthologous genes have subgenomic dominance. Gene collinearity and phylogenetic analysis explain that some PEBP genes play key roles in evolution. Cis-element analysis revealed that PEBP genes are mainly regulated by hormones, light signals and stress-related pathways. Multiple PEPB genes had different expression patterns between early and late-flowering genotypes. Further detection of its response to temperature and photoperiod revealed that PEBPs ArahyM2THPA, ArahyEM6VH3, Arahy4GAQ4U, ArahyIZ8FG5, ArahyG6F3P2, ArahyLUT2QN, ArahyDYRS20 and ArahyBBG51B were the key genes controlling the flowering response to different flowering time genotypes, photoperiods and temperature. This study laid the foundation for the functional study of the PEBP gene in cultivated peanuts and the adaptation of peanuts to different environments.

Abstract
Sugarcane (Saccharum spp.) is an important economic crop for both sugar and biomass, the yields of which are negatively affected by flowering. The molecular mechanisms controlling flowering in sugarcane are nevertheless poorly understood. RNA-seq data analysis and database searches have enabled a comprehensive description of the PEBP gene family in sugarcane. It is shown to consist of at least 13 FLOWERING LOCUS T (FT)-like genes, two MOTHER OF FT AND TFL (MFT)-like genes, and four TERMINAL FLOWER (TFL)-like genes. As expected, these genes all show very high homology to their corresponding genes in Sorghum, and also to FT-like, MFT-like, and TFL-like genes in maize, rice, and Arabidopsis. Functional analysis in Arabidopsis showed that the sugarcane ScFT3 gene can rescue the late flowering phenotype of the Arabidopsis ft-10 mutant, whereas ScFT5 cannot. High expression levels of ScFT3 in leaves of short day-induced sugarcane plants coincided with initial stages of floral induction in the shoot apical meristem as shown by histological analysis of meristem dissections. This suggests that ScFT3 is likely to play a role in floral induction in sugarcane; however, other sugarcane FT-like genes may also be involved in the flowering process.

Abstract
Geophytes, the plants that form vegetative storage organs, are characterized by a dual reproduction system, in which vegetative and sexual propagation are tightly regulated to ensure fitness in harsh climatic conditions. Recent findings highlight the role of the PEBP (PHOSPHATIDYLETHANOLAMINE-BINDING PROTEIN) gene family in geophytes as major players in the molecular cascades underlying both types of reproduction. In this review, we briefly explain the life cycle and reproduction strategies of different geophytes and what is known about the physiological aspects related to these processes. Subsequently, an in-depth overview is provided of the molecular and genetic pathways driving these processes. In the evolution of plants, the PEBP gene family has expanded, followed by neo- and subfunctionalization. Careful characterization revealed that differential expression and differential protein complex formation provide the members of this gene family with unique functions, enabling them to mediate the crosstalk between the two reproductive events in geophytes in response to environmental and endogenous cues. Taking all these studies into account, we propose to regard the PEBPs as conductors of geophyte reproductive development.

Abstract
The phosphatidylethanolamine binding protein (PEBP) family comprises ancient proteins found throughout the biosphere that play an important role in plant growth and development, flowering, seed development and dormancy. However, not all PEBP genes have been identified or analyzed in common wheat (Triticum aestivum L.) and its progenitors. In this study, we identified the PEBP genes in common wheat, Triticum dicoccoides, Triticum urartu and Aegilops tauschii by searching whole genome sequences, and characterized these genes by phylogenetic and transcriptome analyses. A total of 76, 38, 16 and 22 PEBP genes were identified in common wheat, T. dicoccoides, T. urartu and Ae. tauschii, respectively. Phylogenetic analysis classified the PEBP genes into four subfamilies (PEBP-like, MFT-like, TFL-like and FT-like); the PEBP-like subfamily was identified as a new subfamily with genes in this subfamily were conserved in plants. Group 2, 3 and 5 chromosomes of common wheat and its progenitors contained more PEBP genes than other chromosomes. The PEBP genes were conserved in wheat during evolution, and tandem duplication played a more important role in the amplification of PEBP genes than segmental duplication. Furthermore, transcriptome analysis revealed that PEBP genes showed tissue/organ-specific expression profiles and some PEBP genes were induced to express by biotic stresses. Quantitative real-time PCR (qRT-PCR) analysis revealed that seven randomly selected PEBP genes expressed differently during seed germination under cold, drought, flood, heat and salt stress treatments, and five of these genes (TaPEBP1, TaPEBP5, TaPEBP9, TaPEBP66 and TaPEBP69) showed significantly higher expression under different stress treatments, indicating that these genes play important roles during seed germination under stress conditions.

Abstract
OBJECTIVE Despite its efficiency and benefits in treating patients with Robin sequence (RS), the pre-epiglottic baton plate (PEBP) is not widely used. However, its acceptance might improve with specific defined parameters for indication and proper design of the velar extension. We present our 13-year, single-center experience in treating infants with RS using PEBP, focusing on the description and insertion of an endoscopically guided PEBP design along with its complications and limitations. DESIGN AND INNOVATION We recommend PEBP as primary treatment for RS, suggesting a new approach of design adjustment based on endoscopic findings of multilevel upper airway obstruction. SETTING Department of cleft lip and palate. PATIENTS Infants with isolated or syndromic RS, period 2010 to 2019. INTERVENTIONS Pre-epiglottic baton plate treatment, intravelar veloplasty, and hard palate closure after initial PEBP treatment. RESULTS We treated 132 infants (isolated RS, 111; syndromic RS, 21) with PEBP. All infants with isolated RS were discharged within an average of 8 days of PEBP therapy. For them, no tracheotomy or tongue-lip adhesion procedures were needed. Only 4 of the 20 infants discharged with a nasogastric tube needed it for >2 weeks. Intravelar veloplasty and palate closure were performed after 3 and 6 months of initiating PEBP treatment, respectively. CONCLUSIONS Application of an orthodontic device in RS therapy has not been accepted worldwide. We hope that our learning curve and recommendations about PEBP will help the implementation of this highly effective and nonsurgical treatment option.

Abstract
Plant growth and development, particularly the induction of flowering, are tightly controlled by key regulators in response to endogenous and environmental cues. The FLOWERING LOCUS T (FT)/TERMINAL FLOWER 1 (TFL1) family of phosphatidylethanolamine-binding protein (PEBP) genes is central to plant development, especially the regulation of flowering time and plant architecture. FT, the long-sought florigen, promotes flowering and TFL1 represses flowering. The balance between FT and TFL1 modulates plant architecture by switching the meristem from indeterminate to determinate growth, or vice versa. Recent studies in a broad range of plant species demonstrated that, in addition to their roles in flowering time and plant architecture, FT/TFL1 family genes participate in diverse aspects of plant development, such as bamboo seed germination and potato tuber formation. In this review, we briefly summarize the evolution of the FT/TFL1 family and highlight recent findings on their conserved and divergent functions in different species.

Abstract
Background TERMINAL FLOWER 1 (TFL1) is a member of phosphatidylethanolamine-binding protein (PEBP) family, which plays an important role in the determination of floral meristem identity and regulates flowering time in higher plants. Results Five BnaTFL1 gene copies were identified in the genome of Brassica napus. The phylogenetic analysis indicated that all five BnaTFL1 gene copies were clustered with their corresponding homologous copies in the ancestral species, B. rapa and B. oleracea. The expression of the BnaTFL1s were confined to flower buds, flowers, seeds, siliques and stem tissues and displayed distinct expression profiles. Knockout mutants of BnaC03.TFL1 generated by CRISPR/Cas9 exhibited early flowering phenotype, while the knockout mutants of the other gene copies had similar flowering time as the wild type. Furthermore, knock-out mutants of individual BnaTFL1 gene copy displayed altered plant architecture. The plant height, branch initiation height, branch number, silique number, number of seeds per silique and number of siliques on the main inflorescence were significantly reduced in the BnaTFL1 mutants. Conclusions Our results indicated that BnaC03.TFL1 negatively regulates flowering time in B. napus. BnaC03.TFL1 together with the other BnaTFL1 paralogues are essential for controlling the plant architecture.

Abstract
Although Phosphatidylethanolamine-binding protein (PEBP) genes have been identified in several plants, little is known about PEBP genes in pears. In this study, a total of 24 PEBP genes were identified, in which 10, 5 and 9 were from Pyrus bretschneideri genome, Pyrus communis genome and Pyrus betuleafolia genome, respectively. Subsequently, gene structure, phylogenetic relationship, chromosomal localization, promoter regions, collinearity and expression were determined with these PEBP genes. It was found that only PbFT from PEBP genes of P. bretschneideri was relatively highly expressed in leaves during flower bud differentiation. Whereas, expression patterns of TFL1 homologues, gene23124 and gene16540, were different from PbFT in buds. The expression pattern and the treatment of reduction day-length indicated that the expression of PbFT in leaves were regulated by day-length and circadian clock. Additionally, the phenotype of transgenic Arabidopsis suggested that PbFT played a role in not only promoting flower bud differentiation, but also regulating the balance between vegetative and reproductive growth. These results may provide important information for further understanding of the evolution and function of PEBP genes in pears.

Abstract
INTRODUCTION The phosphatidylethanolamine-binding protein (PEBP) gene family plays a crucial role in seed germination, reproductive transformation, and other important developmental processes in plants, but its distribution in Gossypium genomes or species, evolutionary properties, and the fates of multiple duplicated genes remain unclear. OBJECTIVES The primary objectives of this study were to elucidate the distribution and characteristics of PEBP genes in Gossypium, as well as the evolutionary pattern of duplication and deletion, and functional differentiation of PEBPs in plants. METHODS Using the PEBP protein sequences in Arabidopsis thaliana as queries, blast alignment was carried out for the identification of PEBP genes in four sequenced cotton species. Using the primers designed according to the PEBP genome sequences, PEBP genes were cloned from 15 representative genomes of Gossypium genus, and the gene structure, CDS sequence, protein sequence and properties were predicted and phylogenetic analysis was performed. Taking PEBP proteins of grape as reference, grouping of orthologous gene, analysis of phylogeny and divergence of PEBPs in nine species were conducted to reconstruct the evolutionary pattern of PEBP genes in plants. RESULTS We identified and cloned 160 PEBPs from 15 cotton species, and the phylogenetic analysis showed that the genes could be classified into the following three subfamilies: MFT-like, FT-like and TFL1-like. There were eight single orthologous group (OG) members in each diploid and 16 double OG members in each tetraploid. An analysis of the expression and selective pressure indicated that expression divergence and strong purification selection within the same OG presented in the PEBP gene family. CONCLUSION An evolutionary pattern of duplication and deletion of the PEBP family in the evolutionary history of Gossypium was suggested, and three pairs of genes resulted from different whole-genome duplication events.

Abstract
In plant development, the flowering transition and inflorescence architecture are modulated by two homologous proteins, FLOWERING LOCUS T (FT) and TERMINAL FLOWER 1 (TFL1). The florigen FT promotes the transition to reproductive development and flowering, while TFL1 represses this transition. Despite their importance to plant adaptation and crop improvement and their extensive study by the plant community, the molecular mechanisms controlling the opposing actions of FT and TFL1 have remained mysterious. Recent studies in multiple species have unveiled diverse roles of the FT/TFL1 gene family in developmental processes other than flowering regulation. In addition, the striking evolution of FT homologs into flowering repressors has occurred independently in several species during the evolution of flowering plants. These reports indicate that the FT/TFL1 gene family is a major target of evolution in nature. Here, we comprehensively survey the conserved and diverse functions of the FT/TFL1 gene family throughout the plant kingdom, summarize new findings regarding the unique evolution of FT in multiple species, and highlight recent work elucidating the molecular mechanisms of these proteins.

Abstract
Numerous studies have provided evidence regarding the involvement of protein S-nitrosylation in the progression of Alzheimer's disease (AD) pathology and its implication in the formation and accumulation of misfolded protein aggregates. The identification of S-nitrosylated proteins can be a major step toward the understanding of mechanisms leading to neuronal degeneration. The present study targeted S-nitrosylated proteins in AD hippocampus, substantia nigra and cortex using the following work-flow that combines S-nitrosothiol-specific antibody detection, classical biotin switch method labeled with fluorescence dye followed by electrospray ionization quadrupole time of flight tandem MS (ESI-QTOF MS/MS) identification. Endogenous nitrosocysteines were identified in 45 proteins, mainly involved in metabolism, signaling pathways, apoptosis and redox regulation as assigned by REACTOME and KEGG pathway database analysis. Superoxide dismutase (SOD2) [Mn], fructose-bisphosphate aldolase C (ALDOC) and voltage-dependent anion-selective channel protein 2 (VDAC2) showed differential S-nitrosylation signal, not previously reported in AD regions. Extensive neuronal atrophy with increased protein S-nitrosylation in AD regions is also evident from immunofluorescence studies using S-nitrosocysteine antibody. A number of plausible cysteine modification sites were predicted via Group-based Prediction System-S-nitrosothiols (GPS-SNO) 1.0 while STRING 8.3 analysis revealed functional annotations in the modified proteins. The findings are helpful in characterization of functional abnormalities and may facilitate the understanding of molecular mechanisms and biological function of S-nitrosylation in AD pathology.
