Genome-Wide Identification and Characterization of Lectin Receptor-Like Kinase Gene Family in Cucumber and Expression Profiling Analysis under Different Treatments.


ABSTRACT: Lectin receptor-like kinases (LecRLKs) are a class of membrane proteins found in plants that are involved in diverse functions, including plant development and stress responses. Although LecRLK families have been identified in a variety of plants, a comprehensive analysis has not yet been undertaken in cucumber (Cucumis sativus L.). In this study, 46 putative LecRLK genes were identified in the cucumber genome, including 23 G-type and 22 L-type, and one C-type LecRLK gene. They were unequally distributed on all seven chromosomes, with a clustering tendency. Most of the genes in the cucumber LecRLK (CsLecRLK) gene family lacked introns. In addition, there were many regulatory elements associated with phytohormones and stress on these genes' promoters. Transcriptome data demonstrated distinct expression patterns of CsLecRLK genes in various tissues. Furthermore, we found that each member of the CsLecRLK family had its own unique expression pattern under hormone and stress treatment by the quantitative real-time PCR (qRT-PCR) analysis. This study provides a better understanding of the character and function of the LecRLK gene family in cucumber and opens up the possibility to exploring the roles that LecRLKs might play in the life cycle of cucumber.
