A wheat salt tolerance introgression line SR3 allele of sro 1,a gene encoding a poly(ADP ribose)polymerase(PARP)domain protein,was identified to be crucial for both seeding growth vigor and abiotic resistance of SR3.sro1 is also found to be involved in the maintenance of genomic integrity.We show here that the wheat SRO has PARP activity; such activity could be manipulated to improve the growth of seedlings exposed to salinity stress by modulating redox homeostasis and maintaining genomic stability.Both the overexpression of Tasro1 in wheat and its heterologous expression in Arabidopsis promote the accumulation of ROS,mainly by enhancing the activity of NADPH oxidase.Moreover,it promotes the activity of ascorbate-GSH cycle enzymes and GSH peroxidase cycle enzymes,which regulate ROS content and cellular redox homeostasis.
