Abstract Cold stress severely impacts the quality and yield of grapevine (Vitis L.). In this study, we extend our previous work to elucidate role regulatory mechanisms Vitis amurensis MYB transcription factor 4a (VaMYB4a) in grapevine's response cold stress. Our results identified VaMYB4a as a key positive regulator We demonstrated that undergoes phosphorylation by V. CBL-interacting protein kinase 18 (VaCIPK18) under stress, process activates transcriptional activity. Using ChIP-seq,...
Cold stress can limit the growth and development of grapevines, which ultimately reduce productivity. However, mechanisms by grapevines respond to cold are not yet fully understood. Here, we characterized an APETALA2/ethylene response factor (AP2/ERF) was shown be a target gene our previously identified VaMYB4a from Amur grape. We further investigated molecular interactions between VaERF054-like transcription factors in grapes their role tolerance. Our results demonstrated that directly...
In globally cultivated grapevines, low-temperature stress poses a persistent challenge. Although COLD1 is recognized as cold receptor in rice, its function grapevine signaling unclear. Here, we identified VaCOLD1, transmembrane protein from the cold-tolerant Vitis amurensis Rupr, which primarily located on plasma and endoplasmic reticulum membranes. Broadly expressed across multiple tissues, VaCOLD1 responds to various environmental stresses, particularly cold. Its promoter contains distinct...
