　　Leaf senescence in plants involves both positive and negative transcriptional regulations.Here we show evidence for the single-stranded DNA (ssDNA) binding protein WHIRLY1 (WHY1) that functions as an upstream suppressor ofWRKY53 in a developmental stage-dependent manner during leaf senescence in Arabidopsis.WHY1 mutant (why1) displayed an early senescence phenotype.
