Transcriptome analysis of exogenous trehalose in response to abiotic stress in grapes

Grapevine is an important economic fruit tree, and European grape (Vitis vinifera L.) has been widely used in fresh food, drying, winemaking and grape seed extract. However, most European grapes have low resistance to low temperature, drought and salt stress, and these abiotic stresses will limit the growth and development of grapes, thereby affecting the grape quality and yield. Many reports have shown that exogenous or endogenous trehalose can help improve plant stress resistance. Therefore, in order to investigate the function and molecular mechanism of trehalose metabolism in grape response to stress, this project was conducted.

葡萄是重要的经济果树，欧洲葡萄（Vitis vinifera L.）已广泛应用于鲜食、制干、酿酒及葡萄籽提取物生产领域。然而，多数欧洲葡萄对低温、干旱与盐胁迫的抗性较弱，此类非生物胁迫会限制葡萄的生长发育，进而影响其品质与产量。已有多项研究表明，外源或内源海藻糖（trehalose）可帮助提升植物抗逆性。因此，为探究海藻糖代谢在葡萄响应胁迫过程中的功能与分子机制，本项目开展了此项研究。
