Polyamines are considered as plant growth regulating compounds; among them, cadaverine has been correlated with root growth promotion or osmotic stress mitigation in some plant species. The purpose of this study was to evaluate the capacity of bacterial Azospirillum brasilense Az39 strain to produce cadaverine in chemically defined medium and inoculated plants, and to correlate this capacity wi...

Potassium (K) is the foremost macronutrients for growth of plant, soil health and fertility. The huge application NPK chemical fertilizers negatively impacts economy a threat to environmental sustainability. rapid depletion K mineral in due agrochemicals agricultural fields production crops India. In present investigation, K-solubilizing microbes (KSM) were isolated enumerated from cereal growi...

Bacterial endophytes with capacity to promote plant growth and improve plant tolerance against biotic and abiotic stresses have importance in agricultural practice and phytoremediation. A plant growth-promoting endophyte named Klebsiella sp. LTGPAF-6F, which was isolated from the roots of the desert plant Alhagi sparsifolia in north-west China, exhibits the ability to enhance the growth of whea...

Phytoremediation of creosote-contaminated soil was monitored in the presence of Tall fescue, Kentucky blue grass, or Wild rye. For all three grass species, plant growth promoting rhizobacteria (PGPR) were evaluated for plant growth promotion and protection of plants from contaminant toxicity. A number of parameters were monitored including plant tissue water content, root growth, plant chloroph...

Recently, emission of volatile organic compounds (VOCs) has emerged as a mode of communication between bacteria and plants. Although some bacterial VOCs that promote plant growth have been identified, their underlying mechanism of action is unknown. Here we demonstrate that indole, which was identified using a screen for Arabidopsis growth promotion by VOCs from soil-borne bacteria, is a potent...

Recent studies show that Mortierella elongata can perform plant-growth promotion across different types of crops, including bahiagrass, corn, tomato, squash, and watermelon. Compared to the well-known species have plant-growth-promotion abilities (e.g., mycorrhizal fungi, Trichoderma), growers, agents, stakeholders are not familiar with "Mortierella" despite important role these fungal taxa pla...

Brassinosteroids are plant natural products with structural similarities to animal steroid hormones. They are found throughout the plant kingdom, and when applied exogenously at nanomolar to micromolar levels in a number of test systems, they exhibit a wide spectrum of physiological effects, including a marked promotion of cell elongation [1]. Like animal steroid hormones, brassinosteroids regu...
