TaWRKY42-B positively regulates JA-induced leaf senescence in Arabidopsis. (a) Senescence-related phenotypes of 7th and 8th leaves of 4-week-old Col-0 and TaWRKY42-B-overexpressing (TaWRKY42-B-OE) plants before and after treated with mock or 100 μM MeJA. Chlorophyll content (b) and ion leakage rate (d) of detached leaves before and after treatment as shown in (a). (c) Transcription of TaWRKY42-B was examined after MeJA treatment in wheat. Seven-day-old wheat seedlings were treated with 200 μM MeJA for 1, 2, 4, 6, 8, 10 and 24 h. (Error bars indicate SD. Asterisks indicate significant differences. Student’s t-test, *P < 0.05, **P < 0.01)
