浙贝母胚胎发育晚期丰富蛋白FtLEA14、编码基因和应用
By cloning the coding sequence of FtLEA14, a protein abundant in the late embryonic development of Fritillaria thunbergii, and constructing a recombinant expression vector, the FtLEA14 gene was overexpressed, which solved the water loss problem of Fritillaria thunbergii under drought conditions, improved the drought resistance of the plant, and ensured the yield and quality of the medicinal material.

AI Technical Summary
Fritillaria thunbergii often encounters seasonal drought during its growth period, which affects the quality and yield of the medicinal material. Current technology has not been able to effectively utilize the function of LEA protein in Fritillaria thunbergii.
The coding sequence of FtLEA14, a protein abundant in the late embryonic development of Fritillaria thunbergii, was cloned. The recombinant expression vector pHB-FtLEA14-YFP was constructed, and the drought stress resistance of the plant was improved by reducing leaf water loss rate through overexpression of the FtLEA14 gene.
It significantly reduced the water loss rate of tobacco leaves and enhanced the drought resistance of the plant, providing a theoretical basis for improving the drought resistance and ensuring the yield of Fritillaria thunbergii.
