BERLINER, ., and TORREY, J. G. 1989. On tripartite Frankia-mycorrhizal associations in the Myricaceae. Can. J. Bot. 67: 1708-1712. Actinomycorrhizal symbiosis was studied in Comptonia peregrina (L.) Coult. and in Myrica gale L., both of the Myricaceae. Root nodules were common in all Comptonia plants in their natural habitats and in pot cultures under greenhouse conditions. Spontaneous actinorh...

silicon (si) is considered as one of the beneficial elements for plants that play important roles in plant resistance to stresses. in this experiment, the effects of three levels of silicon (0, 0.85 and 1.7 mm) on the growth and physiological processes of pumpkin were studied in plants inoculated with sphaerotheca fuliginea (250000 conidia ml−1) and non-inoculated plants under hydroponic condit...

HIGHLIGHTS Azospirillum brasilense stimulates root growth in maize under water deficit. Maize inoculated with A. shows greater photosynthesis drought conditions. Under deficit, plants showed use efficiency (WUE).

ABSTRACT- The increasing population and the pastures inability to meet food needs in livestock have led to the increase of cultivates forage plants. In order to evaluate the effect of plant growth promoting rhizobacteria (PGPR) and alfalfa (Medicago sativa) extract on the growth and concentration of macronutrient and micronutrient contents of  forage sorghum (Sorghum vulgare), an experiment was...

a factorial experiment based on completely randomized design with three replications was carried out in order to study the effect of different strains of mesorhizobium ciceri on chickpea tolerance under drought stress. in the first step of experiment, five native cultivars of chickpea (bivanij, arman, greet, jam and hashem) were inoculated with eight native (c-15, c-22, swri7, swri9 and swri4) ...

the present study was conducted to determine the plant growth-promoting activities of bradyrhizobium sp. (vigna) strain mrm6 grown in the presence and absence of the selected herbicides, quizalafop-p-ethyl and clodinafop. the herbicide tolerant bradyrhizobium sp. (vigna) strain mrm6 was further tested for bioremediation and plant growth promoting potential using greengram as a test crop, grown ...

In the last years, there is a growing demand for plants used in traditional medicine. Licorice (Glycyrrhiza glabra) contains different phytocompounds, that have demonstrated various pharmacological activities. The endophytic fungus, Piriformospora indica, has been reported to enhance the growth of host plants and allow them to survive under abiotic and biotic stress. This study was undertaken t...

The use of hydroponic systems for cultivation in controlled climatic conditions and the selection of suitable genotypes for the specific environment help improving crop growth and yield. We hypothesized that plant performance in hydroponics could be further maximized by exploiting the action of plant growth-promoting organisms (PGPMs). However, the effects of PGPMs on plant physiology have been...

Endophytic Sporosarcina aquimarina SjAM16103 was isolated from the inner tissues of pneumatophores of mangrove plant Avicennia marina along with Bacillus sp. and Enterobacter sp. Endophytic S. aquimarina SjAM16103 was Gram variable, and motile bacterium measured 0.6-0.9 μm wide by 1.7-2.0 μm long and light orange-brown coloured in 3-day cultures on tryptone broth at 26°C. Nucleotide sequence of...

Flock house virus (FHV), a single-stranded RNA insect virus, has previously been reported to cross the kingdom barrier and replicate in barley protoplasts and in inoculated leaves of several plant species [Selling, B. H., Allison, R. F. & Kaesberg, P. (1990) Proc. Natl. Acad. Sci. USA 87, 434-438]. There was no systemic movement of FHV in plants. We tested the ability of movement proteins (MPs)...
