Drought or water stress is a limiting factor that hampers the growth and yield of edible crops. Drought-tolerant plant growth-promoting rhizobacteria (PGPR) can mitigate in crops by synthesizing multiple bioactive molecules. Here, strain PAB19 recovered from rhizospheric soil was biochemically molecularly characterized, identified as Enterobacter sp./Leclercia adecarboxylata (MT672579.1). Strain tolerated an exceptionally high level drought (18% PEG-6000) produced indole-3-acetic acid (176.2 ± 5.6 µg mL−1), ACC deaminase (56.6 5.0 salicylic (42.5 3.0 2,3-dihydroxy benzoic (DHBA) (44.3 2.3 exopolysaccharide (204 14.7 alginate (82.3 6.5 solubilized tricalcium phosphate (98.3 3.5 presence 15% polyethylene glycol.

Plants defend themselves against ecological stresses including drought. Therefore, they adopt various strategies to cope with stress, such as seepage and drought tolerance mechanisms, which allow plant development under conditions. There is evidence that microbes play a role in tolerance. In this study, we presented review of the literature describing initiation mediated by inoculation fungi, bacteria, viruses, several bacterial elements, well transduction pathways identified via archetypal functional or morphological annotations contemporary “omics” technologies. Overall, microbial associations potential mediating protection responses drought, an important factor for agricultural manufacturing systems are affected fluctuating climate.

Medicinal plants (MPs) are important resources widely used in the treatment and prevention of diseases have attracted much attention owing to their significant antiviral, anti-inflammatory, antioxidant other activities. However, soil degradation, caused by continuous cropping, excessive chemical fertilizers pesticide residues heavy metal contamination, seriously restricts growth quality formation MPs. Microorganisms, as major biota soil, play a critical role restoration land ecosystem. Rhizosphere microecology directly or indirectly affects development, metabolic regulation active ingredient accumulation Microbial resources, with advantages economic efficiency, harmless environment non-toxic organisms, been recommended promising alternative conventional pesticides. The introduction beneficial microbes promotes adaptability MPs adversity stress enhancing fertility, inhibiting pathogens inducing systemic resistance. On hand, it can improve medicinal removing pollutants, reducing absorption harmful substances regulating synthesis secondary metabolites. ecological benefits microbiome agricultural practices increasingly recognized, but current understanding interaction between conditions, root exudates microbial communities mechanism rhizosphere affecting metabolism is still quite limited. More research needed investigate effects on different species.

Agriculture production faces many abiotic stresses, mainly drought, salinity, low and high temperature. These stresses inhibit plants’ genetic potential, which is the cause of huge reduction in crop productivity, decrease potent yields for important plants by more than 50% imbalance agriculture’s sustainability. They lead to changes physio-morphological, molecular, biochemical nature change regular metabolism, makes them a leading losses productivity. plant systems also help mitigate stress conditions. To initiate signal during conditions, sensor molecules perceive from outside commence signaling cascade send message stimulate nuclear transcription factors provoke specific gene expression. stress, contain several methods avoidance, adaption, acclimation. In addition these, manage possess tolerance mechanisms involve ion transporters, osmoprotectants, proteins, other associated with transcriptional control, cascades are stimulated offset stress-associated molecular changes.
