Arbuscular mycorrhiza-upregulated PtPIP1;2 facilitates H2O2 transport to enhance drought tolerance in trifoliate orange.
Arbuscular mycorrhizal fungi (AMF) can enhance drought tolerance of host plants; however, the underlying molecular mechanisms remain unclear. Here, PtPIP1;2, a plasma membrane intrinsic protein gene strongly induced by AMF (Funneliformis mosseae) colonization under drought stress, was identified. Subcellular localizati...
