Regulation by arbuscular mycorrhizal symbiosis of three tomato plasma membrane H+-ATPase genes (LHA1, LHA2 and LHA4) has been analysed in wild-type and mycorrhiza-defective tomato plants. Expression of these genes was differentially regulated in leaves and roots of both tomato phenotypes after inoculation with Glomus mosseae.

The pot experiments were conducted in the Department of Life Science and Bioinformatics of Assam University, Silchar. The aim of the present study was to investigate the effect of dual inoculation of Arbuscular mycorrhiza (AM) (Glomus fasciculatum) and Rhizobium on the chlorophyll, nitrogen and phosphorus contents of pigeon pea (Cajanus cajan L.). The results revealed an overall increase in chl...

The formation of symbiotic associations with arbuscular mycorrhizal (AM) fungi is a phenomenon common to the majority of vascular flowering plants. Here, we used cDNA arrays to examine transcript profiles in Medicago truncatula roots during the development of an AM symbiosis with Glomus versiforme and during growth under differing phosphorus nutrient regimes. Three percent of the genes examined...

The role of abscisic acid (ABA) during the establishment of the arbuscular mycorrhiza (AM) was studied using ABA sitiens tomato (Lycopersicon esculentum) mutants with reduced ABA concentrations. Sitiens plants and wild-type (WT) plants were colonized by Glomus intraradices. Trypan blue and alkaline phosphatase histochemical staining procedures were used to determine both root colonization and f...

Gaeumannomyces graminis var. tritici causes take-all disease, the most important root disease of cereal plants. Cereal plants are able to form a symbiotic association with soil-borne arbuscular mycorrhizal fungi which can provide bioprotection against soil-borne fungal pathogens. However, the bioprotective effect of arbuscular mycorrhizal fungi against soil-borne fungal pathogens might vary. In...

Some phosphate rocks (PR) contain high concentrations of uranium (U), which are potentially toxic via accumulation in soils and food chains, and plant uptake of U is likely to be influenced by characteristics of roots and associated microorganisms. The relative importance of root hairs and mycorrhiza in U uptake from PR was studied using a root hairless barley (Hordeum vulgare) mutant (Brb) and...

Salinization has led to the deterioration of ecological environment, affected growth plants, and hindered development agriculture forestry. Arbuscular mycorrhizal (AM) fungi, as important soil microorganisms, play significant physiological roles in promoting plant nutrient absorption improving structure. Puccinellia tenuiflora (Turcz.) Scribn. et Merr. Songnen saline-alkaline grassland was sele...

The coffee nursery is susceptible to endoparasitic Pratylenchus coffeae. Application of biological method in the suggested control nematode population and maintain seedling health. objectives this study were observe ability Arbuscular Mycorrhiza Fungi (AMF) Glomus spp. liquid inoculant Helper Bacteria (MHB) consortium Pseudomonas diminuta Bacillus subtilis for increasing AMF colonization reduci...

Arbuscular mycorrhizal fungi (AMF) and dark septate (DSF) are symbionts that associated with the roots of plants, including epiphytic lycophytes ferns. Paris-type mycorrhiza glomoid structures most common forms colonization in these plants. This work aimed to evaluate occurrence ferns as well diversity AMF spores recovered from substrate eleven species. Roots Asplenium gastonis, Campyloneurum a...
