The microbiome associated with crop plants has a strong impact on their health and productivity. Candidatus Liberibacter asiaticus (Las), the bacterial pathogen responsible for Huanglongbing (HLB) disease, lives inside the phloem of citrus plants including the root system. It has been suggested that Las negatively affects citrus microbiome. On the other hand, members of citrus microbiome also i...

UNLABELLED Soil-dwelling microbes solubilize mineral phosphates by secreting gluconic acid, which is produced from glucose by a periplasmic glucose dehydrogenase (GDH) that requires pyrroloquinoline quinone (PQQ) as a redox coenzyme. While GDH-dependent phosphate solubilization has been observed in numerous bacteria, little is known concerning the mechanism by which this process is regulated. H...

The p-cumate-degrading strain Pseudomonas putida F1 and the m- and p-toluate-degrading strain P. putida mt-2 transform indole-2-carboxylate and indole-3-carboxylate to colored products identified here as indigo, indirubin, and isatin. A mechanism by which these products could be formed spontaneously following dioxygenase-catalyzed dihydroxylation of the indolecarboxylates is proposed. Indolecar...

This study determined the concentration of pesticides contaminating soil and water, effect on microbial activity physicochemical properties. Nutrient agar was used for enumeration total heterotrophic bacteria by pour plate method. Enumeration fungi done with Potato Dextrose Agar. Soil CO2-evolution estimated every 5-days 25 days. Total nitrogen using macro-Kjeldhal distillation Available phosph...

Bacteria that inhabit the rhizosphere of agricultural crops can have a beneficial effect on crop growth. One such mechanism is the microbial-driven solubilization and remineralization of complex forms of phosphorus (P). It is known that bacteria secrete various phosphatases in response to low P conditions. However, our understanding of their global proteomic response to P stress is limited. Her...

to evaluate the effects of pgpr foliar spraying on forage and grain yield of forage sorghum (var. speedfeed), a farm experiment was conducted in research farm of college of agriculture, university of tehran in 2009. the experimental design consisted of a randomized complete blocks consisting of 17 treatments in every block. in this research, the effect of foliar application of 16 different stra...

Based on a detailed study conducted to isolate microbes from soil samples collected from various tea gardens located in the Indian Himalayan region, two bacteria namely Bacillus subtilis and Pseudomonas corrugata have been selected as promising inoculants for field application in tea gardens. Bioassays based on the inoculation of seed raised and tissue culture raised tea plants had earlier indi...

Application of seed inoculation with active nodule bacteria strains increases crop productivity legumes and reduces the impact negative environmental factors. The effectiveness complex has not been studied thoroughly. purpose study was to determine endophytic on plant growth development, rhizosphere microbiota, soybean in irrigated soil Southern Steppe Ukraine. In field research, seeds ultra-ea...

The interactive effect of phosphate-solubilizing bacteria and arbuscular mycorrhizal (AM) fungi on plant use of soil P sources of low bioavailability (endogenous or added as rock phosphate [RP] material) was evaluated by using soil microcosms which integrated (sup32)P isotopic dilution techniques. The microbial inocula consisted of the AM fungus Glomus intraradices and two phosphate-solubilizin...
