Fig. 1From: Genome-wide survey and expression analysis of GRAS transcription factor family in sweetpotato provides insights into their potential roles in stress responseInter-chromosomal relations of IbGRAS genes in sweetpotato chromosomes. Chromosomes LG1-LG15 are indicated by colored rectangles. The gene density on each chromosome is depicted by the heatmap along each rectangle. The colored curves represent duplicated IbGRAS gene pairs. The corresponding IbGRAS genes located in segmental duplications are marked with colorsBack to article page
