Simplified exon-intron organisation. Coding sequences (CDSs) and untranslated regions (UTRs) are indicated with black and grey boxes, respectively. Arrows indicate the positions of introns that are well conserved among 82 subclade IVa members from G. max, M. truncatula, and L. japonicus. Grey dashed arrows show the positions of introns found in some subclade IVa members. Details are provided in Additional file 1: Table S3
