In contrast to Arabidopsis roots (cruciferae), legume roots are able to interact symbiotically with soil microorganisms, and develop two types of secondary lateral organs (lateral roots and nodules). Alterations in root branching patterns, lateral and adventitious root organogenesis and total root length have been observed in response to external soil conditions. In
