Salinity is one of the abiotic stresses adversely affecting plant growth and productivity. Salt tolerance of plants requires knowledge of the physiological mechanisms and recognition of genes, which affect plant tolerance at different plant growth stages. Recently, the researchers try to improve plant tolerance to salt stress via biofertilizers treatments such as arbuscular mycorrhizal (AM) fungi. AM fungi colonize plant root system and improve plant growth by various ways. This chapter focuses on the mechanisms of the AM fungi, which improve salt tolerance of host plants. These mechanisms include the improved nutrient uptake (N, P, Ca, and Mg), maintenance of the K+/Na+ ratio, biochemical changes (accumulation of sugar, proline, betaines, and antioxidant enzymes) and physiological changes (water status, relative permeability, chlorophyll concentration, and abscisic acid accumulation). |
