文摘
- •
SpBADH, from Sesuvium portulacastrum was isolated.
- •
Its expression was up-regulated by NaCl, PEG6000, H2O2, ABA and higher temperature.
- •
Overexpression of SpBADH in Arabidopsis could increase tolerance to drought/osmotic stresses.
- •
SpBADH can activate antioxidative enzymes to improve ROS scavenging.
