A laboratory study was carried out to evaluate the protective role of ectomycorrhizal fungi against contamination of plants growing in soil treated with cadmium at a dose of 150 μg Cd/ g soil. An alginateimmobilized inoculum of mycorrhizal fungi was used to introduce the fungi to the soil. The impact of fungi was examined in terms of changes in cadmium levels in inoculated and non-inoculated se...

Infection structures were observed at the penetration sites on the leaves of cucumber plants inoculated with Colletotrichum orbiculare using a fluorescence microscope. The cucumber plants were previously drenched with suspension of bacterial strains Pseudomonas putida or Micrococcus luteus. The plants pre-inoculated with both bacterial strains were resistant against anthracnose after inoculatio...

A new mycorrhizal fungal strain was isolated from hair roots of Rhododendron fortunei Lindl. grown in Huading Forest Park, Zhejiang Province, China. Morphological characterization and internal transcribed spacer rDNA analysis suggested that it belongs to Oidiodendron maius Barron, and we designated it as strain Om19. Methods for culturing Om19 were established, and the ability of Om19 to form m...

Plant growth promoting rhizobacteria (PGPR) hold promising future for sustainable agriculture. Here, we demonstrate a carotenoid producing halotolerant PGPR Dietzia natronolimnaea STR1 protecting wheat plants from salt stress by modulating the transcriptional machinery responsible for salinity tolerance in plants. The expression studies confirmed the involvement of ABA-signalling cascade, as Ta...

A study was performed to investigate the efficiency of microbial inoculants after encapsulating in alginate supplemented with humic acid on plant growth. Two promising plant growth promoting rhizobacteria were identified by 16S rDNA sequencing as Pseudomonas putida CC-FR2-4 and Bacillus subtilis CC-pg104, which were further characterized by biochemical analyses and inoculated to Lectuca sativa ...

Pennisetum pedicellatum plants were inoculated with Glomus mosseae, G. aggregatum and Gigaspora margarita. There were both quantitative and qualitative changes in the protein pattern of inoculated plants. Gi. margarita induced increase in protein in the plants. Acid phosphatase, alkaline phosphatase, superoxide dismutase and chitinase activities were high at the beginning of infection, but decl...

Pepper lines L57 and L113 and cv.Pico are inoculated by 1, 5, 10, 25, 75 μg/ml cucumber mosaic virus (CMV) in inoculum. Both lines are resistant to the virus and cv.Pico is used as a susceptible control. The lines respond with the development of chlorotic (L57) and necrotic (L113) spots on the inoculated leaf. The virus is established only in the inoculated leaves and their petioles of the resi...

The purpose of the present study was to investigate the effect of plant growth-promoting rhizobacteria(PGPR) on physiological and biochemical properties of maize (Zea mays L.) in different cultivation methods under water stress. The experiment was carried out as split-plot design including water stress (well-watered, mild stress, and severe stress) as main plot and also cultiv...
