a, Numbers of shared and unique orthologous protein-coding gene clusters in peanut (AHAB), A. duranensis (Aradu) and A. ipaensis (Araip). b, The number of single-copy gene sets is presented (blue), retained as a single copy (orange) or lost (gray) in the peanut A or B subgenomes. c, Maximum likelihood tree of ARF gene family, with 114, 28 and 28 members in peanut, A. duranensis, and A. ipaensis, respectively. Branch values represent the percentage of 1,000 bootstrap replicates supporting the topology. Scale bar represents substitutions per site. d, Chromosome distributions of genes involved in fatty acid metabolism, symbiotic nitrogen fixation pathways and biotic stress resistance in cultivated peanut, from outer to inner circles representing chromosomes, R genes, acyl-lipid-related and nodulation-related genes.
