Fig. 3From: Molecular evolution of candidate male reproductive genes in the brown algal model EctocarpusTopology of Esi0130_0068 as predicted by Phyre2 and Blast2GO. The extracellular and cytoplasmic sides of the membrane are labeled and the beginning and end of each transmembrane helix are indicated by the residue index. Positively selected sites identified by PAML 4 are marked with orange arrows, sites identified by HyPhy are marked in blueBack to article page
