Demonstrates that VaTPS9 enhances cold tolerance in grapevines, suggesting its potential use in breeding programs.

Key Points

The research aimed to identify the role of the VaTPS9 gene in regulating cold tolerance in Vitis amurensis.
Analyzed the expression patterns of VaTPS9 in different tissues over time
Cloned and sequenced the VaTPS9 gene
Conducted functional analyses through gene overexpression in various plant models
Implemented virus-induced gene silencing to assess cold sensitivity in grapevine plantlets
VaTPS9 showed the highest expression in one-year-old shoots during winter
Overexpression of VaTPS9 enhanced cold tolerance in yeast and Arabidopsis thaliana
Silencing VaTPS9 increased cold sensitivity in grapevine plantlets
VaTPS9 positively regulates cold tolerance by modulating trehalose metabolism and ROS homeostasis
