Among the abiotic stresses, drought is first environmental stress responsible for a decrease in agricultural production worldwide; it affects plants various ways, including slowing down plant growth and disrupting its general physiology. Arbuscular mycorrhizal symbiosis growth-promoting rhizobacteria (PGPR) are considered to be bioameliorators of plant’s resistance water stress. The present stu...

We studied the effect of constitutive expression of pathogenesis-related proteins (PRs) in tobacco plants on vesicular-arbuscular mycorrhiza. Tobacco lines genetically transformed to express various PRs constitutively under the control of the cauliflower mosaic virus 35S promoter of tobacco were examined. Immunoblot analysis and activity measurements demonstrated high levels of expression of th...

A comparison was made of water-soluble root exudates and extracts of Sorghum vulgare Pers. grown under two levels of P nutrition. An increase in P nutrition significantly decreased the concentration of carbohydrates, carboxylic acids, and amino acids in exudates, and decreased the concentration of carboxylic acids in extracts. Higher P did not affect the relative proportions of specific carboxy...

Twenty medicinal plants were investigated for Vesicular-arbuscular mycorrhizal (VAM) association in a survey of the Pandam area of Darjeeling Himalaya, West Bengal. Vesicular-arbuscular mycorrhiza was found to be of universal occurrence in almost all plants located at different regions of the globe except a few one under varied eco-habitats. Great variations were found in the VAM infection perc...

Abstract The symbiotic relationship between mycorrhizal fungi and plant roots provides benefits to the host plant. Fusarium wilt, caused by oxysporum, is most common disease on chili (Capsicum annuum), resulting in production losses of up 50%. Until now, efforts control wilt still rely chemical which has a negative impact environment.The purpose this study was examine existence number Mycorrhiz...

Abstract Background PROTEIN PHOSPHATASE 2A (PP2A) expression is crucial for the symbiotic association between plants and various microbes, knowledge on these processes important sustainable agriculture. Here we tested hypothesis that PP2A regulatory subunits, especially B’φ B’θ, are involved in signalling mycorrhizal fungi or plant-growth promoting bacteria. Results Treatment of tomato ( Solanu...
