Auxin Modulated Initiation of Lateral Roots Is Linked to Pericycle Cell Length in Maize

Auxin is essential in regulating root system architecture as it controls primary root elongation and lateral root formation. It has been reported that exogenous auxin inhibits primary root elongation and promotes the formation of LR; in maize roots this last process is considered to be initiated from four pericycle cells. In this paper, LR formation in Zea mays primary root has been quantatatively evaluated after exogenous auxin treatments by...
