Notably, the hormone regulates the formation and emergence of lateral roots (LRs). In Arabidopsis thaliana the initiation of lateral root primordia (LRP) is induced by auxin and takes place deep within the parental root. Also, the emergence of the LRP through the overlying tissues is regulated by auxin. It has been shown that the gene LAX3 is expressed in cortical and epidermal directly overlying a LRP. External auxin induces LAX3's expression in all cortical and epidermal cells suggesting that it actsas the activating signal.
