Altered expression of GPLα in transgenic plants results in modified progression of leaf senescence. a, d Inhibited senescence in transgenic plants (Col-0 background) overexpressing GPLα (GPLα OE) during natural leaf senescence (a, left panel) and artificial dark-induced senescence (d, left panel). Accelerated senescence in GPLα-silenced transgenic plants (GLPα SI) during natural leaf senescence (a, middle panel) and artificial dark-induced senescence (d, middle panel). Accelerated senescence in GPLα-mutant plants (GLPα KO) during natural leaf senescence (a, right panel) and artificial dark-induced senescence (d, right panel). b, c Effects of overexpression or suppression of GPLα expression on total chlorophyll (b) and protein (c) contents during natural leaf senescence. e, f Effects of overexpression or suppression of GPLα expression on total chlorophyll (e) and protein (f) contents during dark-induced leaf senescence. Three independent transgenic lines were examined. Asterisks indicate significant differences within each compared pair (P < 0.05, Student’s t test, ±SD). WT (Col), wild type
