The growth stage of soybean (Glycine max (L.) Merrill) at the time of inoculation was determined to be a factor in the severity of seed coat mottling caused by Bean pod mottle virus (BPMV, Genus Comovirus, Family Comoviridae). The virus caused seed coat mottling, and reduced seed size and seed weight. The effects of different isolates of BPMV on seed coat mottling in soybean were found to vary ...

Several Salmonella enterica outbreaks have been traced back to contaminated tomatoes. In this study, the internalization of S. enterica Typhimurium via tomato leaves was investigated as affected by surfactants and bacterial rdar morphotype, which was reported to be important for the environmental persistence and attachment of Salmonella to plants. Surfactants, especially Silwet L-77, promoted i...

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)...

Micromonospora is a Gram positive bacterium that can be isolated from nitrogen fixing nodules from healthy leguminous plants, where they could be beneficial to the plant. Their plant growth promoting activity in legume and non-legume plants has been previously demonstrated. The present study explores the ability of Micromonospora strains to control fungal pathogens and to stimulate plant immuni...

effects of arbuscular mycorrhizal fungus (glomus mossea ca) and plant growth promoting rhizobacteria (pgpr) of bacillus pantea and psedomonas putida were evaluated on growth parameters of osteospermum (osteospermum hybrida ‘passion mix’) under different watering conditions (field capacity, two and one third of field capacity). arbuscular mycorrhizal fungus (amf) and pgpr were applied as single ...

Drought is one of the most important factors worldwide, which limits crop production, especially in semi-arid areas. The use beneficial microorganisms such as arbuscular mycorrhizal fungi (AMF) may represent an eco-friendly and biological technique to increase crops yields ensure food security. purpose this paper was evaluate effect AMF inoculation on a promised variety hulless barley (Hordeum ...

Sugarcane interacts with particular types of beneficial nitrogen-fixing bacteria that provide fixed-nitrogen and plant growth hormones to host plants, promoting an increase in plant biomass. Other benefits, as enhanced tolerance to abiotic stresses have been reported to some diazotrophs. Here we aim to study the effects of the association between the diazotroph Gluconacetobacter diazotrophicus ...

The elemental composition of strawberry plants (Fragaria ananassa cv. Macarena) inoculated with the plant growth-promoting bacterium Azospirillum brasilense REC3, and non-inoculated controls, was studied using scanning electron microscopy (SEM) and energy dispersive X-ray (EDS) analysis. This allowed simultaneous semi-quantification of different elements in a small, solid sample. Plants were in...

Two-node cuttings of cassava cultivar SS4 were inoculated with 1,000 infective juveniles of Meloidogyne incognita at 1, 14, 40, 70, 88, and 127 days after planting (DAP). Plant growth and root damage were assessed at 150 DAP. Meloidogyne incognita significantly reduced the number of storageroots formed in plants inoculated at 14, 40, 70, and 88 DAP and the total weight of storage-roots in plant...

Photosynthesis, primary productivity, N content, and N(2) fixation were determined as a function of applied NH(4) (+) in peas (Pisum sativum L. cv. Alaska) which were inoculated or not inoculated with Rhizobium leguminosarum. Cabon dioxide exchange rate (CER) increased 10-fold, total N content 7-fold, and total dry weight 3-fold in 26-day-old uninoculated plants as applied NH(4) (+) was increas...
