“…Gibberellic acid (GA) positively regulates cell division and elongation, hypocotyl and stem growth, and leaf and root meristem size (Guo et al, 2015 ; Wang et al, 2015 ; Martínez et al, 2016 ). GA signaling is a key factor in the inhibition of plant growth under stress (Magome and Kamiya, 2016 ; Martínez et al, 2016 ). PGPRs can influence the endogenous GA levels in plants (Bottini et al, 2004 ; Kang et al, 2014a ; Shahzad et al, 2016 ).…”
