Mycorrhizas enhance drought tolerance of trifoliate orange by enhancing activities and gene expression of antioxidant enzymes

Original language description

A pot experiment was carried out to investigate the responses of leaf antioxidant enzyme defense systems to an arbuscular mycorrhizal fungus (AMF), Funneliformis mosseae, in trifoliate orange (Poncirus trifoliata) seedlings exposed to drought stress (DS). An eight-week soil drought treatment notably decreased root mycorrhizal colonization, root surface area and volume, total plant biomass, leaf relative water content, and leaf chlorophyll a, b, and a + b concentrations, while these variables were significantly greater in mycorrhizal seedlings than in non-mycorrhizal seedlings. There was significantly higher leaf catalase (CAT) activity in AMF-inoculated seedlings versus non-AMF-inoculated seedlings under well-watered (WAN) conditions. Under DS, leaf superoxide dismutase (Fe-SOD, Mn-SOD, and Cu/Zn-SOD) and CAT activities were dramatically increased with AMF inoculation. Leaf PtMn-SOD and peroxidase (PtPOD) gene expressions were significantly increased by AMF treatment under WW. Under DS, the relative expression of leaf PtMn-SOD, PtCAT1, and PtPOD was increased by AMF, while leaf PtFe-SOD and PtCu/Zn-SOD expressions were down-regulated. Such higher antioxidant enzyme activities and corresponding gene expressions in mycorrhizal plants under DS indicated their greater capacity to mitigate the oxidative damage of drought, as evidenced by the lower concentrations of malondialdehyde, superoxide radical, and hydrogen peroxide in AMF-inoculated plants.
