The translocator protein (TSPO), previously designated as peripheral-type benzodiazepine receptor, is a protein mainly located in the outer mitochondrial membrane of eukaryotic cells. TSPO is implicated in major physiological functions and functionally associated with other proteins such as the voltage-dependent anionic channel, also designated as mitochondrial porin. Surprisingly, a TSPO-relat...

Targeted gene inactivation and metabolic profiling revealed that the cryptic PKS-NRPS gene cluster in the genome of the plant commensal Pseudomonas fluorescens Pf-5 codes for the biosynthesis of antiproliferative and antifungal rhizoxin derivatives.

In Pseudomonas fluorescens CHA0, mutation of the GacA-controlled aprA gene (encoding the major extracellular protease) or the gacA regulatory gene resulted in reduced biocontrol activity against the root-knot nematode Meloidogyne incognita during tomato and soybean infection. Culture supernatants of strain CHA0 inhibited egg hatching and induced mortality of M. incognita juveniles more strongly...

Abstract Endophytic bacteria have been reported to roles as biocontrol agents and plant growth promoters. The application of endophytic in the form mixed culture [consortia] will provide better effectiveness than when applied alone. This study aimed obtain a consortium that is effective biological control for purple blotch [ Alternariaporri ], promote yield shallots. research was arranged compl...

Field research was conducted in Poland from 2019–2021 to determine the effect of bacteria Azospirillumlipoferum Br17 and Azotobacter chroococcum, as well companion red clover on total protein content yield grain spring barley cultivated a system organic agriculture. Two factors were examined field experiment: I. bacterial formulations: 1—control, 2—nitrogen-fixing (Azospirillumlipoferum Br17, c...

Eleven endophytic bacteria were isolated from the roots of cumin, a medicinal plant grown in Assiut Province, Egypt. The strains KAU2025 and KAU2022 exhibited highest inhibition rate against Fusarium oxysporum (FOC7) (64%) dual culture test selected for further studies. identified as Brevibacillus parabrevis Pseudomonas fluorescens, respectively, based on 16S rDNA sequence analysis. isolates in...

Pseudomonas sp. strain KENGFT3 inhibits the growth of Phytophthora infestans and is a potentially useful biopesticide for plant diseases, including potato late blight. We sequenced the 6.2-Mbp genome of this strain and assembled it into a single scaffold with 9 contigs. KENGFT3 is related to previously sequenced strains of P. fluorescens.

The fixation of a beneficial mutation represents the first step in adaptation, and the average effect of such mutations is therefore a fundamental property of evolving populations. It is nevertheless poorly characterized because the rarity of beneficial mutations makes it difficult to obtain reliable estimates of fitness. We obtained 68 genotypes each containing a single fixed beneficial mutati...

From the strain 51W of Pseudom onas fluorescens living under extrem e conditions at the Schirm acher Oasis (A ntarctica) a pyoverdin was obtained. Its structure was elucidated by chemical degradation and spectroscopic methods. The NM R data of the pyoverdin and of its G a(III) complex were com pared. A ppreciable influences of the m etal on the chemical shifts of the atom s at its binding sites...

The effects of temperature and inoculum density of Fusarium oxysporum f. sp. ciceris race 5 on suppression of Fusarium wilt in chickpea (Cicer arietinum) cv. PV 61 by seed and soil treatments with rhizobacteria isolated from the chickpea rhizosphere were studied in a model system. Disease development over a range of temperatures (20, 25, and 30 degrees C) and inoculum densities (25 to 1,000 chl...
