GAI gain-of-function partially rescues the early-senescence phenotype of WRKY75 overexpressing plants. (A) The senescence phenotypes of the indicated genotypes. (B) Relative chlorophyll content of the indicated genotypes. (C) Membrane ion leakage of the indicated genotypes. (D) and (E) qRT-PCR analysis of transcript levels of senescence marker genes in the indicated genotypes. For B-D, values are means ± SD of three independent biological replicates. ∗P < 0.05, ∗∗P < 0.01, Student's t-test compared with Col-0. These experiments were performed three times with similar results.
