StABI5 regulates chlorophyll catabolism under dark conditions in potato. (A) Overexpressed StABI5 (StABI5-OE) transgenic potato leaves accelerate yellowing and senescence under dark conditions. (B) Chlorophyll contents of StABI5-OE transgenic potato and Desiree leaves under dark conditions. The data represent an average of five leaves with three duplicates. Error bars indicate ±SD for triplicates. Asterisks denote Student’s t-test significant differences as compared with Desiree potatoes (* P <0.05; ** P < 0.01). (C) Transcription levels of chlorophyll metabolism-related genes PGSC0003DMG400012666 (StRBCS_2C), PGSC0003DMG400013416 (StCAB3C), PGSC0003DMG400002261 (StCV) and PGSC0003DMG400030219 (StNYC1) in StABI5-OE transgenic potato lines and Desiree leaves when treated with continuous darkness for 0, 2 and 4 days.
