Soil saline-alkalization is a major abiotic stress that leads to low iron (Fe) availability and high toxicity of sodium ions (Na+) for plants. It has recently been shown that plant growth promoting rhizobacteria (PGPR) can enhance the ability of plants to tolerate multiple abiotic stresses such as drought, salinity, and nutrient deficiency. However, the possible involvement of PGPR in improving...

The current study was undertaken to evaluate in vitro the antileishmanial activity of three plants growing wild in Algeria : Juglans regia, Lawsonia inermis and Salvia officinalis. The hydroalcoholic extracts of these plants were tested on the growth of the promastigotes of Leishmania major. The plant extract effects were compared with three controls : CRL1 composed of 1 ml RPMI inoculated with...

Plant growth-promoting rhizobacteria (PGPR) induce positive effects in plants, such as increased growth or reduced stress susceptibility. The mechanisms behind PGPR/plant interaction are poorly understood, as most studies have described short-term responses on plants and only a few studies have analyzed plant molecular responses under PGPR colonization. Here, we studied the effects of the PGPR ...

We used medic (Medicago truncatula) to investigate effects of inoculation with two arbuscular mycorrhizal (AM) fungi and application of arsenate (AsV) and phosphate (Pi) on mechanisms underlying increased tolerance (in terms of growth) of AM plants to AsV. We tested the hypotheses that (1) inoculation with AM fungi results in down-regulation of MtPht1;1 and MtPht1;2 genes (encoding high-affinit...

Herbivorous pests and arbuscular mycorrhizal fungi (AMF) coexist on the same host plant, having an indirect effect one another. We established experiment in a randomised complete block design with four treatments six replications to examine impact of AMF population damage caused plane trees by leafhopper Zyginella pulchra. Manure, manure plus fertiliser, fertiliser AMF, non-inoculated ...

The effect of mycorrhiza fungi was studied on growth and yield of potato (Solanum tuberosum L.) in Fereidoonshahr, Esfahan, Iran during 2013 growing season. The experiment treatments were arranged in a factorial design based on a complete randomized block design with three replications. Four phosphorus fertilizer levels of 25%, 50% 75% and 100% P recommended with two levels of Mycorrhiza: with ...

The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...

Phytophthora root and stem rot due to sojae is a major constraint of soybean production. This study evaluated the combined effect P. inoculation flooding on growth seedlings. The cultivar ‘Enrei’ was grown in greenhouse pots containing vermiculite containers field soil. plants were inoculated with two isolates subjected flooding. ratio dead live ranged from 0 0.32 across all treatments. Pathoge...

Eucalyptus cultivation has expanded considerably in Brazilian systems, leading to the current search for technologies to optimize growing conditions and the production of seedlings in nurseries. Based on the understanding that the development of tree species such as Eucalyptus sp. can be influenced by endophytic fungi that act directly as plant growth-promoting species, cloned seedlings of Euca...
