Bacillus pumilus plays an essential role in agricultural applications as a biological control and for biosafety concerns. However, the underlying mechanisms of B. pumilus strains remain unclear. In our previous study, B. pumilus SH-9 was isolated and shown to be a causal agent of drought stress tolerance and enhanced agronomic traits. Bacillus pumilus SH-9 was isolated from the rhizosphere soil of Artemisia vulgaris. NGS (next generation sequencing) was performed for the strain to gain new insights into the molecular mechanisms underlying plant-microbial interactions. NGS revealed 3,910 genes, 3294 genes with protein-coding, and 11 functional genomic regions related to diverse agronomic traits. Several gene clusters related to the biosynthesis of phytohormones, stress tolerance, and agricultural diversification were predicted. The genome provides insights into the possible mechanisms of this bacterium and its future applications. The genomic organization of SH-9 revealed several hallmarks of its plant growth promotion and pathogen suppression activities. Our results provide detailed genomic information for the SH-9 strain and reveal its potential stress tolerance mechanisms, which lays the foundation for the development of effective biocontrol strategies against abiotic stress.

“…This strategy could be more widely accepted and prevent the rapid growth of pathogen resistance to these antibacterial substances [12]. Currently, the indirect mode of action through the induction of resistance in the host plant is given great attention in terms of disease control [112]. Induced resistance presents the possibility of long-term and thorough disease management by utilizing the intrinsic disease resistance of plants.…”

Postharvest disease management is vital to increase the quality and productivity of crops. As part of crop disease protection, people used different agrochemicals and agricultural practices to manage postharvest diseases. However, the widespread use of agrochemicals in pest and disease control has detrimental effects on consumer health, the environment, and fruit quality. To date, different approaches are being used to manage postharvest diseases. The use of microorganisms to control postharvest disease is becoming an eco-friendly and environmentally sounds approach. There are many known and reported biocontrol agents, including bacteria, fungi, and actinomycetes. Nevertheless, despite the abundance of publications on biocontrol agents, the use of biocontrol in sustainable agriculture requires substantial research, effective adoption, and comprehension of the interactions between plants, pathogens, and the environment. To accomplish this, this review made an effort to locate and summarize earlier publications on the function of microbial biocontrol agents against postharvest crop diseases. Additionally, this review aims to investigate biocontrol mechanisms, their modes of operation, potential future applications for bioagents, as well as difficulties encountered during the commercialization process.

“…Plant stress usually reflects some sudden changes in environmental conditions which create unfavourable conditions for the growth and development of the plants [1]. Stress occurring in plants can be divided into two primary categories namely abiotic stress and biotic stress [2]. Abiotic stress is imposed on plants by either physical or chemical factors of the environment [3], while biotic stress exposed to the plants are biological entities like weeds, pathogens, insects, pests, etc.…”

Plant stresses are the conditions that adversely affect the growth, development, or productivity of plants/trees and can be caused by various physical, chemical, and biological factors. However, stress caused by the influence of heavy metals has a notable adverse effect on plant growth and productivity. These heavy metal contaminations are responsible for the harmful effects on biotic (plants and associated organisms) and the abiotic (soil, water, and air) environment. If not properly managed, mining activities are considered to be the prime source of heavy metal contamination in the surrounding environment. Phytoremediation may effectively remediate a wide range of heavy metal contaminants in different environments and hence offers an effective, carbon-neutral, and ecologically beneficial method for the removal of hazardous heavy metal contaminants. Phytoremediation enhances the growth and development of plants and nourishes the environment resulting in the ill effects of climate extremes in disturbed areas and hence mitigating the impacts of climate change. Phytoremediation has been widely studied for the remediation of heavy metal stress but it hasn't yet achieved commercial viability in degraded ecosystems of India where it is required the most. Through this review article, we tried to minimize this gap by reviewing some important phytoremediation studies in India which successfully reduced the negative impacts of heavy metals in different degraded ecosystems.
