“…However, heavy application of fertilizers and pesticides in agriculture can be damaging to the ecosystem and human health. Metal toxicity is widespread in fields and farms as a consequence of chemical fertilizers and pesticides [242][243][244][245]. The impact on the soil microbiota, on the other hand, is complicated and varied.…”

Rhizospheric organisms have a unique manner of existence since many factors can influence the shape of the microbiome. As we all know, harnessing the interaction between soil microbes and plants is critical for sustainable agriculture and ecosystems. We can achieve sustainable agricultural practice by incorporating plant-microbiome interaction as a positive technology. The contribution of this interaction has piqued the interest of experts, who plan to do more research using beneficial microorganism in order to accomplish this vision. Plants engage in a wide range of interrelationship with soil microorganism, spanning the entire spectrum of ecological potential which can be mutualistic, commensal, neutral, exploitative, or competitive. Mutualistic microorganism found in plant-associated microbial communities assist their host in a number of ways. Many studies have demonstrated that the soil microbiome may provide significant advantages to the host plant. However, various soil conditions (pH, temperature, oxygen, physics-chemistry and moisture), soil environments (drought, submergence, metal toxicity and salinity), plant types/genotype, and agricultural practices may result in distinct microbial composition and characteristics, as well as its mechanism to promote plant development and defence against all these stressors. In this paper, we provide an in-depth overview of how the above factors are able to affect the soil microbial structure and communities and change above and below ground interactions. Future prospects will also be discussed.

“…Increased SA levels alter cytoplasmic redox, causing disulphide bonds to be cleaved in NPR1 (Non-Expressor PR1) oligomers, which controls their transport to the nucleus. Following the translocation of NPR1 monomers from cytosol into the nucleus, it works as a co-transcription factor with TGA transcription factor (TF) and activates genes involved in defence [ 64 , 137 ]. SA signalling pathway is important for plant defence mechanism by inducing resistance to infection against hemi-biotrophic and biotrophic pathogens while JA is primarily involved in modulating disease resistance against necrotrophic pathogens [ 138 ].…”

The agriculture sector has been put under tremendous strain by the world’s growing population. The use of fertilizers and pesticides in conventional farming has had a negative impact on the environment and human health. Sustainable agriculture attempts to maintain productivity, while protecting the environment and feeding the global population. The importance of soil-dwelling microbial populations in overcoming these issues cannot be overstated. Various processes such as rhizospheric competence, antibiosis, release of enzymes, and induction of systemic resistance in host plants are all used by microbes to influence plant-microbe interactions. These processes are largely founded on chemical signalling. Producing, releasing, detecting, and responding to chemicals are all part of chemical signalling. Different microbes released distinct sorts of chemical signal molecules which interacts with the environment and hosts. Microbial chemicals affect symbiosis, virulence, competence, conjugation, antibiotic production, motility, sporulation, and biofilm growth, to name a few. We present an in-depth overview of chemical signalling between bacteria-bacteria, bacteria-fungi, and plant-microbe and the diverse roles played by these compounds in plant microbe interactions. These compounds’ current and potential uses and significance in agriculture have been highlighted.

“…Mutations of these two residues markedly reduced the ability of GAPA1 to bind SA. Taken together, this research offers novel insights into how SA controls energy fluxes in stressed plants while also providing a new dimension to the current paradigm of SA signaling through its interaction with proteins which have not normally been associated with SA [ 73 , 74 ].…”
