Many studies have demonstrated that arbuscular
mycorrhizal (AM) symbiosis is often alleged to improve plant
resistance to water salinity stress through the alteration of
plant physiology and expression of some plant genes, help in
water regulation of plants by extending their hyphae toward
the available moisture zones for continuous water absorption
and translocate it to plants (Giri et al., 2004). Also, AM association
can affect the host plants in terms of stomatal movement and photosynthesis of leaves and increase the
chlorophyll concentration. Different studies have indicated
that AM plants are frequently more tolerant to salt stresses
than non-AM plants (Al-Karaki, 2006), with only few exceptions
(Ouziad et al., 2006).
