Báo cáo khoa học: Cotton GhMPK2 is involved in multiple signaling pathways and mediates defense responses to pathogen infection and oxidative stress doc

... overexpressed GhMPK2 showed an increased ability to scavenge ROS and to tolerate oxidative stress. Thus, this study suggests a role for GhMPK2 in the defense signaling pathways in response to both pathogen ... species scavenging capability and oxidative stress tolerance. These results increased our understanding of the role of the group C GhMPK2 gene in m...
