Mycorrhizal symbiosis down-regulates or does not change root aquaporin expression in trifoliate orange under drought stress
Original language description
Arbuscular mycorrhizas absorb water from soil to host plants, while the relationship between mycorrhizas and aquaporins (AQPs, membrane water channel proteins, which function in water transport) in mycorrhizal plants is unclear. In this study, Funneliformis mosseae-colonized trifoliate orange (Poncirus trifoliate) seedlings were grown in pots fitted with 37-mu m nylon meshes at the bottom of each pot to allow mycorrhizal hyphae absorb water from an outer beaker. The expression of seven plasma membrane intrinsic proteins (PIPs) genes, six tonoplast intrinsic proteins (TIPs) genes, and four nodulin-26 like intrinsic proteins (NIPs) genes were analyzed in roots of both well-watered (WW) and drought stressed (DS) plants. The six-week DS plants dramatically increased hyphal water absorption rate by 1.4 times, as compared with WW plants. Mycorrhizal plants exhibited greater plant growth performance, leaf water status (water potential and relative water content), and gas exchange under both WW and DS conditions. Mycorrhizal inoculation induced diverse expression patterns in these AQPs under WW: up-regulation of PtNIP1 ;1 , PtPIP2;1, and PtPIP2;5, down-regulation of PtNIP1;2, PtNIP6;1, PtPIP1 ;2, PtPIP1;5, PtPIP2;8, PtTIP1;1, PtTIP1;2, PtTIP1;3, and PtTIP5;1, and no changes in other AQPs. However, the expression of PtPIPs and PtIVIPs was down-regulated by mycorrhizal inoculation under DS, and PtTIPs was not induced by mycorrhizal colonization under DS. The expression pattern of AQPs in response to mycorrhizas under DS is a way of mycorrhizal plants to minimize water loss.
