Overexpression of GhWRKY42 in Arabidopsis promotes leaf senescence. a Transcript levels of GhWRKY42 in WT and transgenic lines. b Phenotypes of WT and transgenic lines grown for four, five and seven weeks. c Relative senescent cotyledon ratio of the WT and transgenic lines after four weeks. d Relative senescent true leaf (rosette leaves) ratio of the WT and transgenic lines after five weeks. e Chlorophyll contents of the WT and transgenic lines after seven weeks. AtActin2 served as the reference gene. The bars represent the means ± SEs from three independent experiments. Independent t-tests revealed highly significant (**P < 0.01) differences between the WT and the transgenic lines
