“Study of halotolerant plant growth promoting rhizobacteria (Rhizospheric / endophytic) from mangrove vegetation of Sundarban, West Bengal and their role in sustainable agriculture”.
Soil salinization results in the continuous reduction of agricultural land throughout the world. Salinity, one of the major abiotic stresses, adversely affects plant growth and development as it interferes with several physiological, biochemical, and molecular processes of plants. In this aspect, salt-tolerant plant growth-promoting rhizobacteria (ST-PGPR) may play a crucial role in sustainable agriculture and in meeting the demand for food for an ever-increasing population. The proposed study aims to study the diversity of halotolerant PGPR (Plant Growth Promoting Rhizobacteria) in the mangrove vegetation of Sundarban and characterization in relation to their plant growth promotion for sustainable agriculture. Identification of isolated ST-PGPR strains would be made on the basis of phenotypic characteristics, molecular approaches like 16 S rDNA analysis, MALDI-TOF analysis, FAME analysis, WGS (whole genome sequence) analysis. Attempts will be made to characterize the important PGP (pl

Soil salinization results in the continuous reduction of agricultural land worldwide. Salinity, a major abiotic stressor, adversely affects plant growth and development by interfering with various physiological, biochemical, and molecular processes. These processes include nutrient imbalance, osmotic stress, ionic stress, oxidative stress, membrane destabilization, reduced photosynthetic capacity, protein synthesis, energy and lipid metabolism, DNA replication, protein metabolism, and cell division. Despite the rapid increase in the global population, food production is not sufficient to meet the challenges posed by such growth. In this context, salt-tolerant plant growth-promoting rhizobacteria (ST-PGPR) may play a crucial role in sustainable agriculture to meet the ever-increasing demand for food. ST-PGPR can enhance plant growth, development, and productivity by producing phytohormones, 1- aminocyclopropane-1-carboxylate deaminase (ACC) activity, phosphate solubilization, exopolysaccharide (EPS) production, siderophore production, biological nitrogen fixation, and the synthesis of compatible solutes, among other mechanisms. The generation of reactive oxygen species (ROS) at low concentrations is a natural phenomenon, but at elevated levels, they can cause oxidative damage. Salinity-induced osmotic stress and ionic stress lead to the overproduction of ROS, which, at severe levels, can result in cell and plant death. ST-PGPR can mitigate the overproduction of ROS under saline stress, thereby protecting the plant from oxidative damage. In this discussion, we shed some light on salt stress sensitivity, the impact of salinity, the role of salt-tolerant PGPR, and their mechanisms in promoting plant growth, antioxidant defense, osmotolerance, and ion homeostasis under saline conditions, enabling plants to mitigate salt stress.

ABSTRACT Chromium (Cr) is the most toxic at its hexavalent state. Widespread use of chromium for various anthropogenic activities causing rapid decline of the agricultural productivity is now a major global concern. The purpose of this study was to isolate the plant growth promoting (PGP) chromium-resistant bacteria and characterize it before being applied for bioremediation. A potent Cr-resistant rhizobacterium (CrS2) was isolated from the rice field near an industrial sewage and identified as Raoultella sp. based on 16S rDNA sequence homology with some phenotypic characteristics. The strain exhibited Cr(VI) resistance up to 25 mM and also possesses some important PGP traits. The selected CrS2 strain has varied degrees of resistance to other toxic heavy metals/metalloids like arsenic, cadmium, and lead. The removal capacity of chromium was studied in broth cultures. The appropriate growth media for the strain is peptone yeast glucose media with glucose (0.5%) and peptone (1%) as carbon and nitrogen sources, respectively. The strain removed substantial amount of chromium after media optimization. The chromate reductase (EC.1.6.5.2) activity was constitutive in nature of this strain. Thus, the strain CrS2 may be exploited for bioremediation of Cr(VI) in Cr-contaminated agricultural soil, where it might also enhance plant growth promotion.

Indole acetic acid is a phytohormone which plays a vital role in plant growth and development. The purpose of this study was to shed some light on the production of IAA in roots, nodules, and symbionts of an aquatic legumeNeptunia oleraceaand its possible role in nodular symbiosis. The symbiont (N37) was isolated from nodules of this plant and identified asRhizobium undicolabased on biochemical characteristics, 16S rDNA sequence homology, and DNA-DNA hybridization results. The root nodules were found to contain more IAA and tryptophan than root; however, no detectable amount of IAA was found in root. The IAA metabolizing enzymes IAA oxidase, IAA peroxidase (E.C.1.11.1.7), and polyphenol oxidase (E.C.1.14.18.1) were higher in root than nodule but total phenol and IAA content were reversed. The strain N37 was found to produce copious amount of IAA in YEM broth medium with tryptophan and reached its stationary phase at 20 h. An enrichment of the medium with mannitol, ammonium sulphate, B12, and 4-hydroxybenzaldehyde was found to promote the IAA production. The presence of IAA metabolizing enzymes and IAA production with PGPR traits including ACC deaminase activity of the symbionts was essential for plant microbe interaction and nodule function.

SOCIAL, ECONOMIC, or ACADEMIC BENEFITS
Unique multi heavy metal resistant 5 bacterial strains (Bacillus cereus MCC3402, Bacillus aryabhattai MCC3374, Bacillus megaterium MCC3375, Bacillus flexus MCC3379 and Bacillus aryabhattai MCC3380) have been finally selected. All these strains identified as several species of Bacillus and resistant to arsenic as highest MIC than other metals are substantial level. These strains were potential organism for bioremediation of corresponding metals pollution. In vitro condition, these strains helpful in inducing plant growth and reducing toxicity as they decrease the level of stress-induced SOD and MDA in rice plant. In addition, they also have ACC deaminase activity and several other PGP traits, including siderophore production.
