“…Moreover, OsPSKR 8 showed the most significant change (increase) in its expression on exposure to Xoc strains CFBP7331, CFBP7341, CFBP7342 and B8-12 while other members showed downregulation in their expression upon infection. This results depicted the involvement of OsPSKRs in regulating stress response in rice plant against Xoc as has been reported previously [ 27 ].…”

“…Our study will help researchers in understanding the role of phytosulfokine receptor mediated signalling during different stages of plant life span and also how it is involved in plant response to environmental cues. [4,27]. It leads to auto and cross phosphorylation of PSKR and other proteins [19].…”

“…In a recent study, it has been shown that plants overexpressing a rice gene LOC_Os02g41890 (named as OsPSKR1) exhibit enhanced resistance to RS105, a strain of Xanthomonas oryzae pv. oryzicola (Xoc) that causes bacterial leaf streak in rice, and also activates the expression of pathogenesis-related genes involved in the salicylic acid pathway [4,27].…”

Peptide signalling is an integral part of cell-to-cell communication which helps to relay the information responsible for coordinating cell proliferation and differentiation. Phytosulfokine Receptor (PSKR) is a transmembrane LRR-RLK family protein with a binding site for small signalling peptide, phytosulfokine (PSK). PSK signalling through PSKR promotes normal growth and development and also plays a role in defense responses. Like other RLKs, these PSKRs might have a role in signal transduction pathways related to abiotic stress responses. Genome-wide analysis of phytosulfokine receptor gene family has led to the identification of fifteen putative members in the Oryza sativa genome. The expression analysis of OsPSKR genes done using RNA-seq data, showed that these genes were differentially expressed in different tissues and responded specifically to heat, salt, drought and cold stress. Furthermore, the real-time quantitative PCR for fifteen OsPSKR genes revealed temporally and spatially regulated gene expression corresponding to salinity and drought stress. Our results provide useful information for a better understanding of OsPSKR genes and provide the foundation for additional functional exploration of the rice PSKR gene family in development and stress response.

“…A network of hormonal and other responses with respect to soil conditions is involved in attuning the growth and development of a plant to its environment (Passioura, 2002). The composition of microorganisms in the soil is closely related to plant health (Chaparro et al, 2012;Yang et al, 2019). For example, rhizosphere microorganisms can not only promote plant growth but also improve the drought resistance of crops (de Vries et al, 2020).…”

Soil microorganisms can form a stable dynamic system with plant root systems. The composition of the soil microorganism community is related to the growth and stress resistance of plants; in turn, soil microorganisms are also regulated by plant genotypes and root exudates. Therefore, research on how to identify microorganisms that are beneficial or harmful to plants, study the interaction between microorganisms and plants, and form stable microbial communities for better plant growth plays an important role in sustainable agriculture. It is of great significance to identify and analyze rhizosphere microorganisms and plant endophytes through high-throughput methods, especially to analyze which microorganisms are beneficial to plants, which are harmful to plants, and which are opportunistic pathogens. This review provides a theoretical basis and outlook for the utilization of beneficial microbes in sustainable agriculture.
