Plants encounter various stresses in their natural environments and can effectively respond to only one stress at a time. Through complex gene network, transcription factors (TFs) such as WRKY TFs regulate diverse array of responses. The clarification the structural characteristics proteins, along with recent advancements molecular dynamics simulations, has shed light on formation, stability, interactions DNA–protein complexes. This provided novel viewpoint regarding control TFs. investigation superfamilies, encompassing historical development, diversity, evolutionary patterns, become feasible due transcriptome approach’s capacity provide extensive comprehensive transcripts. significance lies pivotal role within several signaling cascades regulatory networks that influence plant defense present review summarizes functional aspects high-volume sequence data from different species studied date.

Abstract Transcription factors (TFs) play crucial roles in plant development and pathogen defense. However, viruses can exploit TFs to facilitate their infection or transmission. In this study, we confirmed the βC1 proteins, encoded by tobacco curly shoot virus (TbCSV)- tomato yellow leaf curl China (TYLCCNV)-associated betasatellites, interacted with GLABROUS1 enhancer binding protein (GeBP) from solanaceous plants including Nicotiana benthamiana , Solanum lycopersicum S. tuberosum Capsicum annuum . Further analysis verified nuclear localization, homodimerization, DNA-binding ability of GeBP TFs, along its interaction nucleus. PVX-mediated overexpression NbGeBP showed no effect on accumulation viral betasatellite DNAs N. after TbCSV heterologous betasatellite, malvastrum vein associated (MaYVB), homologous TbCSB. both MaYVV caused a decrease expression during early stages infection, regardless presence implying that might role infection. TbCSV/TbCSB TYLCCNV/TYLCCNB infect many plants, proteins interact TbCSB TYLCCNB. The yeast two-hybrid bimoleccular fluorescence complementation assays AtGeBP Arabidopsis thaliana could not βC1, revealing GeBP-βC1 interactions only exist plants.
