“…The improved growth of AM inoculated plants has been attributed to enhanced acquisition of mineral nutrients with low mobility, such as P, Zn, Cu and Fe (Al-Karaki, 2000), and to decreased uptake of Na + (Al-Karaki, 2006). Porras-Soriano et al (2009) found increased plant growth and ability to acquire N, P and K from saline media in young olive trees inoculated with the Glomus species.…”

ABSTRACTindex peaked at day 61 (42.5%) and decreased to 7.8% by day 89. Inoculation with AM fungi increased plant dry matter accumulation by 7%, especially stem DM, compared to -AM plants. Generally, growth rates were higher in the +AM plants; ULR increased more in the second half of the experiment in inoculated plants compared to noninoculated. The mycorrhizal infection enhanced leaf area growth, which resulted in increased LAR and SLA, especially during the initial phases of the experiment.

“…(Landwehr et al, 2002). However, when comparing several Glomus spp., Porras-Soriano et al (2009) observed that each AM fungal species has a different efficiency in alleviating plant salt stress. Recently, Khare and Rai (2012) have investigated taxonomic diversity of AM fungi in alkaline soils of upper Gangetic plains of district Allahabad and adjoining areas and it was found that such soils have a detrimental effect on AM spore population, distribution and diversity.…”

“…The discrepancies amongst studies suggest that various AM fungal spp. have varying tolerance to salinity, then questioning the host plant and AM fungus compatibility and tolerance (Porras-Soriano et al, 2009). These studies also suggest that AM fungal species have different capacities in protecting plants and that host compatibility might be an issue worth looking into when developing AM strategies in plant growth and tolerance under salt stress conditions.…”

Several environmental factors adversely affect plant growth and development and final yield performance of a crop. Drought, salinity, nutrient imbalances (including mineral toxicities and deficiencies) and extremes of temperature are among the major environmental constraints to crop productivity worldwide. Development of crop plants with stress tolerance, however, requires, among others, knowledge of the physiological mechanisms and genetic controls of the contributing traits at different plant developmental stages. In the past two decades, biotechnology research has provided considerable insights into the mechanism of biotic stress tolerance in plants at the molecular level. Furthermore, different abiotic stress factors may provoke osmotic stress, oxidative stress and protein denaturation in plants, which lead to similar cellular adaptive responses such as accumulation of compatible solutes, induction of stress proteins, and acceleration of reactive oxygen species scavenging systems. Recently, various methods are adapted to improve plant tolerance to salinity injury through either chemical treatments (plant hormones, minerals, amino acids, quaternary ammonium compounds, polyamines and vitamins) or biofertilizers treatments (Asymbiotic nitrogen-fixing bacteria, symbiotic nitrogen-fixing bacteria) or enhanced a process used naturally by plants (mycorrhiza) to minimise the movement of Na+ to the shoot. Proper management of Arbuscular Mycorrhizal Fungi (AMF) has the potential to improve the profitability and sustainability of salt tolerance. In this review article, the discussion is restricted to the mycorrhizal symbiosis and alleviation of salinity stress.

“…However, the effectiveness of the mycorrhizal symbiosis varies according to mycorrhizal fungi strains and plant cultivars (SorianoMartin et al, 2006;Binet et al, 2007). Though many investigations have reported the positive effects of arbuscular mycorrhizal fungi (AMF) on morphological and physiological variables related to olive tolerance to water def icit and salt stress (SorianoMartín et al, 2006;Porras-Soriano et al, 2009, Fouad et al, 2012, little is known about their specific action on antioxidant mechanisms which regulate different biochemical changes e.g. protein, enzyme activities, carbohydrates, etc., related to the alleviation of oxidative damage induced by water stress.…”

Olive trees are often subjected to a long dry season with low water availability which induces oxidative stress. The present study was conducted to evaluate the effectiveness of native Rhizophagus manihotis (Rma) and non-native Funneliformis mosseae (Fmo) arbuscular mycorrhizal (AM) fungi (AMF) in enhancing olive protection against oxidative stress induced by water deficit. Olive plantlets, cv. Picholine marocaine, were inoculated (AM-plants) or not (NM-plants) with Rma or Fmo and subjected to well-watered (75% of field capacity) or water-stressed (25% of field capacity) conditions. After two months, obtained results showed that water stress significantly decreased growth and biomass production of NM-plants, but AMF alleviated the detrimental effects of water deficit on the growth of olive plants. Inoculation with Rma increased shoot height by 120%, root length by 56%, fresh weight by 170% (shoot) and 210% (root), and dry weight by 220% (shoot) and 220% (root) compared to NM-plants. AM colonization enhanced drought tolerance in terms of protection against oxidative stress. Mycorrhizal plants showed lower levels of hydrogen peroxide (H2O2), malondialdehyde (MDA) and electrolyte leakage (EL) than NM-plants. Rma colonization decreased two times H2O2, 2.6 times MDA and two times EL levels compared to NM-plants. This protective effect seems to be due to the enhanced activities of superoxide dismutase (534 U mg-1 protein), catalase (298 U mg-1 protein), guaiacol peroxidase (47 U mg-1 protein), and ascorbate peroxidase (305 U mg-1 protein) which were highest in Rma-plants. Moreover, Rma-plants showed the lowest oxidative damage to lipid and highest soluble protein content. Thus, the native AMF Rma ought to be considered as a biological tool for enhancing olive tolerance to drought.
