Figure 4.
Perception of AtPep1 but not of the MAMPs flg22 or elf18 accelerates dark-induced senescence. Four leaf discs of Col-0 plants were floated on water supplemented with the indicated elicitor peptides or without any peptide (0) and kept for 4 days in continuous darkness. Bars show mean values of the total chlorophyll content of four leaf discs. Error bars represent ±1 SE of the mean and asterisks display Student's t-test results (* = p > 0.05, ** = p < 0.01, ** = p < 0.001, ns = not significant).
