Role of auxin and nitric oxide on growth and development of lateral root of plants: possible involvement of exogenously induced Phot1

Abstract

Development of root architecture including lateral root (LR) formation is a critical event for successful growth of plants. Auxin promotes the production of nitric oxide (NO) in roots, which is required for auxin-mediated root organogenesis. Inhibition of auxin transport reduced PHOT1-GFP expression at the basal and central part of LRs, indicating role of auxin in Phot1 expression in lateral roots. However, the involvement of auxin-mediated NO on Phot1 expression in LR growth and development yet to be explored. This review gives an insight that auxin-mediated NO may lead to LR growth and development through interacting with Phot1. [ J Adv Biotechnol Exp Ther 2018; 1(2.000): 61-64]
