Abstract
Background 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.).Results In this study, 46 putative LecRLK genes were identified in cucumber genome, including 23 G-type, 22 L-type and 1 C-type LecRLK genes. They unequally distributed on all 7 chromosomes with a clustering trendency. Most of the genes in the cucumber LecRLK (Cs LecRLK) gene family lacked introns. In addition, there were many regulatory elements associated with phytohormone and stress on these genes’ promoters. Transcriptome data demonstrated that 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.Conclusion This study provides a better understanding of the evolution and function of LecRLK gene family in cucumber, and opens the possibility to explore the roles that LecRLK s might play in the life cycle of cucumber.
