Abstract Background Bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. ( Xoo ) is one of the most destructive pathogens responsible for severe yield losses in rice. Application bacterial biocontrol agent (BCA) with plant growth promotion (PGP) abilities a promising method that alternates current conventional practices to manage BLB and increase crop yield. Hence, this study ai...

background and objectives: azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.the aim of this study was to isolate azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic pi compounds. materials and methods: in this study, soil samples collected from a diverse range of slightly alkaline soil type...

Nitrogen-fixing, plant-growth promoting bacteria are arguably the biotechnological tool of highest potential to improve agricultural productivity in short term. Nitrogen fixation and phytohormone production by these bacteria have been considered the most important factors for plant growth promotion. However, the underlying mechanisms responsible for productivity increases by associative bacteri...

Plant growth-promoting rhizobacteria (PGPR) are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. Inoculation of crop plants with certain strains of PGPR at an early stage of development improves biomass production through direct effects on root and shoots growth. Inoculation of ornamentals, forest trees, vegetables, and a...

Bacillus amyloliquefaciens ssp. plantarum FZB42 represents the prototype of Gram-positive plant growth promoting and biocontrol bacteria. In this study, we applied transposon mutagenesis to generate a transposon library, which was screened for genes involved in multicellular behavior and biofilm formation on roots as a prerequisite of plant growth promoting activity. Transposon insertion sites ...

Abstract Plant-based screening experiments were conducted with the aim of identifying biocontrol bacteria and fungi for seed treatment maize. Candidate microorganisms evaluated their protective effects against soilborne infections by species Fusarium , Globisporangium (syn. Pythium ) Rhizoctonia. The tested from maize roots or other sources, including some active microbial components commercial...

effects of fe and trichoderma harzianum bi strain on plant growth and development of spathiphyllum were investigated. experiments were carried out in an glasshouse and in pots filled with soil, perlite and coco peat (1:1:1) were used as the growing medium. plant roots (seedlings with three leaves) were inoculated with trichoderma (0 and 8% w/w) as media mixture. fe spray (0, 0.75, 1.5, 3 g/l), ...
