Chilling and freezing can reduce significantly vine survival and fruit set in Vitis vinifera wine grape. To overcome such production losses, a recently identified grapevine C‐repeat binding factor (CBF) gene, VvCBF4, was overexpressed in grape vine cv. ‘Freedom’ and found to improve freezing survival and reduced freezing‐induced electrolyte leakage by up to 2 °C in non‐cold‐acclimated vines. In addition, overexpression of this transgene caused a reduced growth phenotype similar to that observed for CBF overexpression in Arabidopsis and other species. Both freezing tolerance and reduced growth phenotypes were manifested in a transgene dose‐dependent manner. To understand the mechanistic basis of VvCBF4 transgene action, one transgenic line (9–12) was genotyped using microarray‐based mRNA expression profiling. Forty‐seven and 12 genes were identified in unstressed transgenic shoots with either a >1.5‐fold increase or decrease in mRNA abundance, respectively. Comparison of mRNA changes with characterized CBF regulons in woody and herbaceous species revealed partial overlaps, suggesting that CBF‐mediated cold acclimation responses are widely conserved. Putative VvCBF4‐regulon targets included genes with functions in cell wall structure, lipid metabolism, epicuticular wax formation and stress‐responses suggesting that the observed cold tolerance and dwarf phenotypes are the result of a complex network of diverse functional determinants. 相似文献

Cold stress is a major environmental factor that negatively affects plant growth and survival. OST1 has been identified as a key protein kinase in plant response to cold stress; however, little is known about the underlying molecular mechanism. In this study, we identified BTF3 and BTF3L (BTF3‐like), β‐subunits of a nascent polypeptide‐associated complex (NAC), as OST1 substrates that positively regulate freezing tolerance. OST1 phosphorylates BTF3 and BTF3L in vitro and in vivo, and facilitates their interaction with C‐repeat‐binding factors (CBFs) to promote CBF stability under cold stress. The phosphorylation of BTF3L at the Ser50 residue by OST1 is required for its function in regulating freezing tolerance. In addition, BTF3 and BTF3L proteins positively regulate the expression of CBF genes. These findings unravel a molecular mechanism by which OST1‐BTF3‐CBF module regulates plant response to cold stress. 相似文献
