Fig. 1: Distribution of genomic features within the genome assembly of O. viciifolia.

a O. viciifolia grown in the field, b genomic features of O. viciifolia. I, Twenty-eight chromosomes of O. viciifolia; II, Density of Gypsy elements; III, Density of Copia elements; IV, Density of genes; V, GC content; VI, Links of collinear gene blocks of O. viciifolia among four haplotypes. Blue ribbons indicate synteny blocks between chra and chrb, chrb and chrc, and chrc and chrd; green ribbons indicate synteny blocks between chra and chrc and chrb and chrd; and red ribbons indicate synteny blocks between chra and chrd. Each sliding window was 100 kb. c Hi-C interaction heatmap of 28 chromosomes in O. viciifolia. d GC content vs. chromosome number of Fabaceae and non-Fabaceae species, At-A. thaliana, Pp-P. persica, Pt-P. trichocarpa, Vv-V. vinifera, Ad-A. duranensis, Ah-A. hypogaea, La-L. angustifolius, Cc-C. cajan, Vr-V. radiata, Gm-G. max, Lj-L. japonicus, Ov-O. viciifolia, Ca-C. arietinum, Ps-P. sativum, Tp-T. pratense, Mr-M. ruthenica, Mt-M. truncatula, Zm-Z. mays, Os-O. sativa, Hv-H. vulgare, Ta-T. aestivum, As-A. sativa.
