Microbiota Modulation in Blueberry Rhizosphere by Biocontrol Bacteria

چکیده
Microbial interactions in agricultural soils can play important roles the control of soil-borne phytopathogenic diseases. Yields from blueberry plantations southern Spain have been impacted by pathogenic fungus, Macrophomina phaseolina. The use chemical fungicides has common method for preventing fungal infections, but due to their high environmental impact, legislation is increasingly restricting its use. Biocontrol alternatives based on microorganisms becoming important. Using metabarcoding technique, fungi and bacteria were characterized (via 16S ITS regions, respectively) rhizosphere healthy dead plants infected M. phaseolina, which had undergone three different treatments: two biocontrol strategies—one them a mix Pseudomonas aeruginosa Bacillus velezensis other one with amyloliquefaciens—and third treatment consisting application nutrient solution. treatments produced changes bacterial microbiota and, lesser extent, fungi. abundance Fusarium was correlated plants, likely favoring infection presence soil, such as Archaeorhizomyces or Actinospica, could promote survival. genera detected between opens possibility studying new targets that act against identify potential be used strategies.

Isolation and Identification of Rhizosphere Soil Chitinolytic Bacteria and their Potential in Antifungal Biocontrol
Four hundred bacterial isolates were isolated from rhizosphere of some plants collected from Egypt and screened for production of chitinase enzyme. Only four isolates designated MS1, MS2, MS3 and MS4 were the most potent chitinolytic bacterial species. SDS-PAGE analysis of vegetative and sporulated cells of the four isolates revealed that the protein profile of the four isolates were different ...
متن کاملIsolation and Characterization of Rhizosphere Bacteria for the Biocontrol of the Asochyta Rabiei in Iran
Chickpea (Cicer arietinum), a cool season grain legume grown on a surface of 11 million ha with worldwide production of about 9 million tons [1], is cultivated in more than 45 countries throughout the world including Iran where it is grown mostly in rainfed areas and on marginal lands in the province of West Azarbayjan. Ascochyta blight is perhaps the most frequent and damaging disease of chick...

Seven isolates of bacteria (SRI-156, SRI-158, SRI-178, SRI-211, SRI-229, SRI-305 and SRI-360) were earlier reported by us as having potential for biocontrol of charcoal rot of sorghum and plant growth promotion (PGP) of the plant. In the present study, the seven isolates were characterized for their physiological traits (tolerance to salinity, pH, temperature and resistance to antibiotics and f...
متن کاملSystemic resistance induced by rhizosphere bacteria.
Nonpathogenic rhizobacteria can induce a systemic resistance in plants that is phenotypically similar to pathogen-induced systemic acquired resistance (SAR). Rhizobacteria-mediated induced systemic resistance (ISR) has been demonstrated against fungi, bacteria, and viruses in Arabidopsis, bean, carnation, cucumber, radish, tobacco, and tomato under conditions in which the inducing bacteria and ...
