Schematic representation of large-scale synteny blocks between chromosomes and chromosome segments of M. truncatula (Mt) and main cool season grain legumes (Source , with modifications). Chickpea (Cicer arietinum; Ca), faba bean (Vicia faba; Vf), lens (Lens culinaris; Lc), and pea (Pisum sativum; Ps). Bars representing Medicago and pea homologous chromosomal regions are shown with the same gray intensity or pattern. Arrows in the boxes indicate the orientation of the chromosomes (short arm - long arm) in the case of Medicago. The corresponding synteny blocks of faba bean, chickpea and lentil are represented by blank bars. The bars do not reflect the relative sizes of chromosome or chromosome segments and the break points of chromosomes are indicated approximately. The figure integrates data from [11, 13, 53–58] and this study.
