Chl composition analysis of the wild-type, the 637ys mutant, the 502ys mutant and the 637ys 502ys double mutant (DM). The elution profiles of Chls in wild-type ZH11 and Nipponbare (a), 637ys (b), 502ys (c) and DM (d) were detected at 660 nm by using HPLC. Peaks 2, 3, 4, and 5 represent Chlphy a, ChlTHGG a, ChlDHGG a, and ChlGG a, respectively. Peaks 1, 6 and 7 represent Chlphy b, ChlDHGG b, and ChlGG b, respectively. The absorption spectra of elution profiles in acetone are the same as those in Additional file 1: Figure S1c and d
