[PMID: 39354936 PMCID: PMC11442278 DOI: 10.3389/fpls.2024.1445839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/08/2024] [Accepted: 08/15/2024] [Indexed: 10/03/2024]
Abstract
The black currant (Ribes nigrum L.), a member of the Saxifragaceae family's Ribes genus, has gained consumer and grower acceptance due to its high nutritional value and economic potential. However, powdery mildew, the primary leaf disease affecting black currants, significantly impacts growers and the industry. Developing varieties highly resistant to powdery mildew is currently considered the most scientifically sound solution. However, the black currant's physiological and disease resistance mechanisms post-infection by powdery mildew remain understudied, thereby impeding further breeding efforts. Therefore, this study aimed to elucidate the pathogenesis of powdery mildew in various susceptible varieties, post-infection physiological changes, and molecular mechanisms related to powdery mildew. This was achieved through phenotypic observation, physiological data analysis, transcriptomic analysis, and qRT-PCR-mediated gene expression analysis.

Comprehensive Review on Bimolecular Fluorescence Complementation and Its Application in Deciphering Protein-Protein Interactions in Cell Signaling Pathways. Biomolecules 2024; 14:859. [PMID: 39062573 PMCID: PMC11274695 DOI: 10.3390/biom14070859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2024] [Revised: 07/14/2024] [Accepted: 07/15/2024] [Indexed: 07/28/2024] Open
Abstract
Signaling pathways are responsible for transmitting information between cells and regulating cell growth, differentiation, and death. Proteins in cells form complexes by interacting with each other through specific structural domains, playing a crucial role in various biological functions and cell signaling pathways. Protein-protein interactions (PPIs) within cell signaling pathways are essential for signal transmission and regulation. The spatiotemporal features of PPIs in signaling pathways are crucial for comprehending the regulatory mechanisms of signal transduction. Bimolecular fluorescence complementation (BiFC) is one kind of imaging tool for the direct visualization of PPIs in living cells and has been widely utilized to uncover novel PPIs in various organisms. BiFC demonstrates significant potential for application in various areas of biological research, drug development, disease diagnosis and treatment, and other related fields. This review systematically summarizes and analyzes the technical advancement of BiFC and its utilization in elucidating PPIs within established cell signaling pathways, including TOR, PI3K/Akt, Wnt/β-catenin, NF-κB, and MAPK. Additionally, it explores the application of this technology in revealing PPIs within the plant hormone signaling pathways of ethylene, auxin, Gibberellin, and abscisic acid. Using BiFC in conjunction with CRISPR-Cas9, live-cell imaging, and ultra-high-resolution microscopy will enhance our comprehension of PPIs in cell signaling pathways.

PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2024; 210:108629.

Abstract
The timing of floral transition is essential for reproductive success in flowering plants. In sugarcane, flowering time affects the production of sugar and biomass. Although the function of the crucial floral pathway integrators, FLOWERING LOCUS T (FT), in sugarcane, has been uncovered, the proteins responsible for FT export and the underlying mechanism remain unexplored. In this study, we identified a member of the multiple C2 domain and transmembrane region proteins (MCTPs) family in sugarcane, FT-interacting protein 1 (ScFTIP1), which was localized to the endoplasmic reticulum. Ectopic expression of ScFTIP1 in the Arabidopsis mutant ftip1-1 rescued the late-flowering phenotype. ScFTIP1 interacted with AtFT in vitro and in vivo assays. Additionally, ScFTIP1 interacted with ScFT1 and the floral inducer ScFT3. Furthermore, we found that the NAC member, ScNAC23, could directly bind to the ScFTIP1 promoter and negatively regulate its transcription. Overall, our findings revealed the function of ScFTIP1 and proposed a potential mechanism underlying flowering regulation in sugarcane.

Abstract
The GRAS (GAI\RGA\SCL) gene family encodes plant-specific transcription factors that play crucial roles in plant growth and development, stress tolerance, and hormone network regulation. Plant dwarfing symptom is mainly regulated by DELLA proteins of the GRAS gene subfamily. In this study, the association between the GRAS gene family and Paulownia witches' broom (PaWB) was investigated. A total of 79 PfGRAS genes were identified using bioinformatics methods and categorized into 11 groups based on amino acid sequences. Tandem duplication and fragment duplication were found to be the main modes of amplification of the PfGRAS gene family. Gene structure analysis showed that more than 72.1% of the PfGRASs had no introns. The genes PfGRAS12/18/58 also contained unique DELLA structural domains; only PfGRAS12, which showed significant response to PaWB phytoplasma infection in stems, showed significant tissue specificity and responded to gibberellin (GA3) in PaWB-infected plants. We found that the internodes were significantly elongated under 100 µmol·L-1 GA3 treatment for 30 days. The subcellular localization analysis indicated that PfGRAS12 is located in the nucleus and cell membrane. Yeast two-hybrid (Y2H) and bimolecular fluorescence complementation (BiFC) assays confirmed that PfGRAS12 interacted with PfJAZ3 in the nucleus. Our results will lay a foundation for further research on the functions of the PfGRAS gene family and for genetic improvement and breeding of PaWB-resistant trees.

Functional studies of four MiFPF genes in mango revealed their function in promoting flowering in transgenic Arabidopsis. JOURNAL OF PLANT PHYSIOLOGY 2023; 285:153994.

Abstract
Flowering promoting factor (FPF) genes play a substantial regulatory role in the process of flowering. In the present study, four MiFPF genes, namely, MiFPF1, MiFPF2, MiFPF3a, and MiFPF3b, were obtained from mango (Mangifera indica L.). Tissue expression analysis showed that MiFPFs were expressed in all mango tissues. Specifically, MiFPF1 and MiFPF2 were highly expressed in leaves, while MiFPF3a and MiFPF3b were highly expressed in flowers and buds. The four MiFPF proteins localize to the nucleus. Overexpression of MiFPFs in transgenic Arabidopsis resulted in early flowering and upregulated the expression of APETAL1 (AP1), FLOWERING LOCUS D (FD) and FLOWERING LOCUS T (FT). MiFPF genes increased the root growth of transgenic Arabidopsis plants under gibberellin treatment. BiFC assays showed that MiFPFs can interact with several DELLA proteins. Taken together, our results demonstrate that the MiFPF gene was involved not only in promoting flowering but also in increasing root growth under gibberellin (GA3) treatment.

Liu F, Zhao P, Chen G, Wang Y, Yang Y. A comparative analysis of small RNA sequencing data in tubers of purple potato and its red mutant reveals small RNA regulation in anthocyanin biosynthesis. PeerJ 2023; 11:e15349. [PMID: 37223121 PMCID: PMC10202107 DOI: 10.7717/peerj.15349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 04/13/2023] [Indexed: 05/25/2023] Open
Abstract
Anthocyanins are a group of natural pigments acting as stress protectants induced by biotic/abiotic stress in plants. Although the metabolic pathway of anthocyanin has been studied in potato, the roles of miRNAs on the metabolic pathway remain unclear. In this study, a purple tetraploid potato of SD92 and its red mutant of SD140 were selected to explore the regulation mechanism of miRNA in anthocyanin biosynthesis. A comparative analysis of small RNAs between SD92 and SD140 revealed that there were 179 differentially expressed miRNAs, including 65 up- and 114 down-regulated miRNAs. Furthermore, 31 differentially expressed miRNAs were predicted to potentially regulate 305 target genes. KEGG pathway enrichment analysis for these target genes showed that plant hormone signal transduction pathway and plant-pathogen interaction pathway were significantly enriched. The correlation analysis of miRNA sequencing data and transcriptome data showed that there were 140 negative regulatory miRNA-mRNA pairs. The miRNAs included miR171 family, miR172 family, miR530b_4 and novel_mir170. The mRNAs encoded transcription factors, hormone response factors and protein kinases. All these results indicated that miRNAs might regulate anthocyanin biosynthesis through transcription factors, hormone response factors and protein kinase.
