“…Therefore, the recognition of Pst is likely an ancestral state before the radiation of the Triticeae and implicates the orthogroup in resistance to adapted and nonadapted pathogens of wheat and barley, respectively. Among the RK LRR-XII subfamily in plants, Pi65 and Pur1 are functionally validated family members that confer resistance to a fungal pathogen ( 56 ). FLS2 and EFR recognize well-conserved epitopes found in many bacteria, flagellin, and EF-Tu, respectively, whereas Xa21 recognizes a tyrosine-sulfated peptide derived from RaxX in Xanthomonas oryzae ( 7 ).…”

In the evolution of land plants, the plant immune system has experienced expansion in immune receptor and signaling pathways. Lineage-specific expansions have been observed in diverse gene families that are potentially involved in immunity but lack causal association. Here, we show that Rps8 -mediated resistance in barley to the pathogen Puccinia striiformis f. sp. tritici (wheat stripe rust) is conferred by a genetic module: Pur1 and Exo70FX12 , which are together necessary and sufficient. Pur1 encodes a leucine-rich repeat receptor kinase and is the ortholog of rice Xa21 , and Exo70FX12 belongs to the Poales-specific Exo70FX clade. The Exo70FX clade emerged after the divergence of the Bromeliaceae and Poaceae and comprises from 2 to 75 members in sequenced grasses. These results demonstrate the requirement of a lineage-specific Exo70FX12 in Pur1-mediated immunity and suggest that the Exo70FX clade may have evolved a specialized role in receptor kinase signaling.

“…The ability of plant viruses to disseminate their genomes from an initially infected cell to nearby cells through a variety of pathways has allowed for both local and systemic virus dissemination in plants. A recent study found a direct contact between BAM1 and the Tobacco Mosaic Virus movement protein, indicating that BAM1 may play a role in the early phases of virus dissemination and the transportation of viral protein from cell to cell [ 72 ]. Crosstalk among RLK-mediated signal transduction pathways can occur when many pathogens are infected at the same time in the same host.…”

“…Arabidopsis BAM1 and CRK28 also showed an essential role in balancing plant growth and stress adaptation. BAM1 is necessary for meristem activity, early anther development, viral migration, and gene silencing [ 72 ]. In addition to the crosstalk and mechanisms mediated by the above examples, the SERK genes also appear to be crucial for plant development under stress.…”

Accompanying the process of growth and development, plants are exposed to ever-changing environments, which consequently trigger abiotic or biotic stress responses. The large protein family known as receptor-like protein kinases (RLKs) is involved in the regulation of plant growth and development, as well as in the response to various stresses. Understanding the biological function and molecular mechanism of RLKs is helpful for crop breeding. Research on the role and mechanism of RLKs has recently received considerable attention regarding the balance between plant growth and environmental adaptability. In this paper, we systematically review the classification of RLKs, the regulatory roles of RLKs in plant development (meristem activity, leaf morphology and reproduction) and in stress responses (disease resistance and environmental adaptation). This review focuses on recent findings revealing that RLKs simultaneously regulate plant growth and stress adaptation, which may pave the way for the better understanding of their function in crop improvement. Although the exact crosstalk between growth constraint and plant adaptation remains elusive, a profound study on the adaptive mechanisms for decoupling the developmental processes would be a promising direction for the future research.

“…The current study clarified the importance of using the monogenic lines that are resistant to blast and use to produce and improve new varieties through the traditional breeding methods. Identification of blast resistance genes are very important in breeding program to improvement new resistance varieties [57,58]. Monogenic lines were produced to help the breeders for identifying and transfer resistance genes by conventional breeding method.…”
