The function of SnRK1 in regulating darkness-induced leaf senescence in cucumber.

SnRK1 (SNF1-related kinase 1), a member of the SNF1 protein kinase superfamily, has been demonstrated to play a role in plant growth and development, as well as in stress responses. In this experiment, the leaf senescence of 'Xintaimici' cucumber was simulated by dark treatment and studied using SnRK1 activator/inhibitor and transient transformation technology. The effects of SnRK1 on cucumber leaf senescence, reactive oxygen species (ROS) metabolism, chloroplast structure, and photosynthetic characteristics were studied.
