Fig. 2.

Domain organization and gene structure of the Class I DcSDGs. The NJ tree was generated using MEGA7 with parameter settings as Fig. 1 based on full-length amino acid sequences of Class I SDG proteins in D. catenatum, P. equestris, Arabidopsis and rice. The number along the tree branch indicates bootstrap value. Different conserved protein domains (SANT, CXC, and SET) are colored as indicated. Gene structures of SDGs in each species were indicated in distinct colors. The solid boxes represent exons and black lines represent introns
