|a Phytohormone signaling is involved in the low-phosphate (LP) response and causes root system changes. To understand the roles of auxin and gibberellic acid (GA) in the maize response to LP stress, inbred line Q319 was used to identify the changes in root morphology and the gene expression response to LP stress with or without exogenous auxin, GA or their inhibitors. The root morphology, IAA and GAs concentration and genes related to the LP response, cell elongation and division, auxin transport and signaling, and GA synthesis and signaling were analyzed. The LP-induced maize root morphological adaption was dependent on changes in the expression of related genes, like IPS1, pht1;1 LPR1b, KRPs, and EXPB1-4. The altered local auxin concentration and signaling were involved in promoting axial root elongation and reducing lateral root density and length under LP conditions, which were regulated by PID and PP2A activity and the auxin signaling pathway. The upregulation of the GA synthesis genes AN1, GA20ox1, and GA20ox2 and the downregulation of the GA inactive genes GA2ox1 and GA2ox2 were observed in maize roots subjected to LP stress, and the increased GA biosynthesis and signaling were involved in root growth. Both hormones participate in LP stress response and jointly regulated root modification and LP acclimation in maize
