title: Arbuscular mycorrhizae reducing water loss in maize plants under low temperature stress.
abstract: Arbuscular mycorrhizal (AM) fungi form mutualistic mycorrhizal symbiotic associations with the roots of approximately 80% of all terrestrial plant species while facilitate the uptake of soil mineral nutrients by plants and in exchange obtain carbohydrates, thus representing a large sink for photosynthetically fixed carbon. Also, AM symbiosis increase plants resistance to abiotic stress such as chilling. In a recent study we reported that AM fungi improve low temperature stress in maize plants via alterations in host water status and photosynthesis. Here, the influence of AM fungus, Glomus etunicatum, on water loss rate and growth of maize plants was studied in pot culture under low temperature stress. The results indicated that low temperature stress significantly decreases the total fresh weight of maize plants, and AM symbiosis alleviate the water loss in leaves of maize plants.
