Fig. 1: The S. tora genome and comparative genomic analysis.

a The landscape of genome assembly (~502 Mb) and annotation of S. tora. Tracks (from outside) correspond to chromosomes (Chr01–Chr13 on a Mb scale), gene density, repeat density, rRNA density, tRNA density, GC content, and GC skew. Tracks are drawn in nonoverlapping 100-kb sliding windows. The red bars in the rRNA and tRNA tracks represent the maximum density of copies on the scale. b An overview of orthologous and paralogous genes among S. tora, related legumes, and V. vinifera. “Uncertain” indicates homologous genes obtained from BLAST but not found using OrthoMCL. “Species-specific” genes do not have any similarity to genes in the other species based on BLAST and OrthoMCL. c Significantly enriched biological process GO and KEGG categories (specialized metabolism) of expanded gene families in S. tora. d Lineage-specific expansion of the CHS-L gene family in S. tora and four other legumes. The 15 tandemly duplicated gene clusters are ordered and shown on chromosome 7, as well as one gene on chromosome 2.
