Development of transgenic tall fescue plants with enhanced tolerance to multiple abiotic stresses

摘要：

Abiotic stress causes a significant decrease in growth and yield of forage crops.Molecular breeding such as genetic transformation has become a popular biotechnological tool for improving forage quality as well as improving tolerance to various abiotic stresses.In the plant cell, SOD and APX are the major antioxidant enzymes for ROS scavenging pathways, and nucleoside‐diphosphate kinase 2(NDPK2) and peroxyredoxin (Prx) are considered as multiple stress tolerant genes with a broad‐range of functions.In this study,we generated transgenic tall fescue plants expressing NDPK2,Prx or both the SOD and APX genes (Lee et al.2007), and investigated their performance to several abiotic stresses.
