Arid regions pose a serious problem for crop production by suppressing plant growth. The use of plant growth promoting rhizobacteria (PGPR) as bioinoculant may be promising to enhance the crop yield in arid conditions. In the present investigation, four strains of cultivable bacteria associated with the rhizosphere of Saccharum L. grown in arid region were isolated using N-free media. Assessmen...

Plant growth-promoting rhizobacteria (PGPR) is a promising solution to improve plant growth under salt stress. Among PGPR, Pseudomonas genus of bacteria that possesses variety mechanisms in promoting and inducing resistance biological as well non-biological This study aimed isolate the from salty-contaminated rhizosphere root collecting at Nam Dinh, also investigate their functions peanut seedl...

Three auxin analogs, 4-, 5-, and 6-azido-3-indoleacetic acid (4-N(3)-IAA, 5-N(3)-IAA, and 6-N(3)-IAA) have been synthesized for use as fluorescent photoaffinity labeling agents. The pK(a) values of these compounds (4-N(3)-IAA, 4.67; 5-N(3)-IAA, 4.65; 6-N(3)-IAA, 4.66; all +/- 0.04) are experimentally indistinguishable from the pK(a) of 3-indoleacetic acid (IAA, 4.69 +/- 0.04). The auxin activit...

Paenibacillus polymyxa has widely been studied as a model of plant-growth promoting rhizobacteria (PGPR). Here, the genome sequences of 9 P. polymyxa strains, together with 26 other sequenced Paenibacillus spp., were comparatively studied. Phylogenetic analysis of the concatenated 244 single-copy core genes suggests that the 9 P. polymyxa strains and 5 other Paenibacillus spp., isolated from di...
