Background:Ralstonia spp. is a major pathogenic microbe for tomato, which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. Ralstonia spp. produces several virulence factors helping it to invade the plant's natural defense mechanism. Native isolates of Trichoderma spp., Pseudomonas fluorescens and B...

MacGee and Doudoroff (2) have gained evidence in support of the postulated scheme by recovering the product of Reaction 1 as a crystalline trisodium salt and establishing its structure as Na3-2-keto-3-deoxy-6-phosphogluconate+2Hz0. Extracts of Pseudomonas Jluorescens catalyze the cleavage of 6-PG to pyruvate and triose phosphate at a rate 10 times faster than the rate of 6-PG dehydrogenase acti...

Enrichment of staple food with zinc (Zn) along solubilizing bacteria is a sustainable and practical approach to overcome Zn malnutrition in human beings by improving plant nutrition, nutrient use efficiency, productivity. Common bean (Phaseolus vulgaris L.) one global population has prospective role agronomic biofortification. In this context, we evaluated the effect diazotrophic bacterial co-i...

A variety of stress situations may affect the activity and survival of plant-beneficial pseudomonads added to soil to control root diseases. This study focused on the roles of the sigma factor AlgU (synonyms, AlgT, RpoE, and sigma(22)) and the anti-sigma factor MucA in stress adaptation of the biocontrol agent Pseudomonas fluorescens CHA0. The algU-mucA-mucB gene cluster of strain CHA0 was simi...

By shedding light on variation in time as well as in space, long-term biogeographic studies can help us define organisms' distribution patterns and understand their underlying drivers. Here we examine distributions of Pseudomonas in and around 15 human homes, focusing on the P. putida and P. fluorescens species groups. We describe recovery from 10,941 samples collected during up to 8 visits per...
