摘要

•AtSPX1 might function as positive regulator of age-triggered leaf senescence in Arabidopsis thaliana.•During leaf ageing, AtSPX1 expression level is dramatically increased, leading to the upregulation of several key senescence-related transcription factors, such as WRKYs and NACs.•AtSPX1 plays a key role in the crosstalk among leaf senescence, Pi starvation and SA signal transduction.
