Fig. 2 in Protochlorophylls in Cucurbitaceae - Distribution, biosynthesis and phylogeny

Fig. 2. (a) A simplified scheme of the biosynthetic pathway of protochlorophylls and non-enzymatic routes leading to protopheophytins. (b) The composition of protochlorophylls and protopheophytins in the seed coats of the species and varieties under investigation. The phylogenetic relationships between these species is represented. The size of each dot corresponds to the relative content of a given compound and is normalized so that the sum of all protochlorophylls in a given species is 100%. The dots are color-coded and arranged as protochlorophylls and protopheophytins in the framed part of panel a. The pigment composition corresponds to that shown in Fig. S2. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
