Distribution of SDH homologous genes in higher plants. Closely related species were specified accordingly. The gene abundance heat map was based on the total copy number of SDH genes in each species. SDHs of P. bretschneideri [39] and E. japonica (loquat) [35] were obtained from literature; additional SDHs may be identified in these two species when complete genome information becomes available. The classification of SDH Class I and SDH Class II was based on the phylogenetic analysis carried out in the present study.
