Fig. 2From: Genome-wide survey of soybean papain-like cysteine proteases and their expression analysis in root nodule symbiosisCollinearity analysis of 19 paralogous segments pairs in GmPLCPs. Duplicated GmPLCP gene pairs are indicated by Green and purple arrows or sticks. The positions of the genes in the positive (to left) and negative (to right) chain of DNA are indicated by the direction of the arrowBack to article page
