Fig. 5From: Overexpression of the protein disulfide isomerase AtCYO1 in chloroplasts slows dark-induced senescence in ArabidopsisHPLC analysis of chlorophyll metabolites in leaves following dark incubation. Data are expressed as the mean ± SE (n = 5-6). For 7-hydroxymethyl chlorophyll a (HM-Chl) and pheophorbide a (Pheide a), relative content uses peak area of the chromatogram.
