biostudies-literatureUnknown43(3)Cheng WThe leucine-rich repeat receptor-like protein kinase (LRR-RLK) gene family is the largest family of the receptor-like protein kinases (RLKs) superfamily in higher plants, which is involved in regulating the plant growth and development, stress responses, signal transduction and so on. However, no comprehensive analyses of LRR-RLKs have been reported in sugarcane. Here, we performed a comprehensive analysis of the LRR-RLK gene family in sugarcane ancestor species <i>Saccharum spontaneum</i>. A total of 437 <i>LRR-RLK</i> genes were identified and categorized into 14 groups based on a maximum likelihood phylogenetic tree. The chromosome location showed an uneven distribution on all 32 chromosomes in sugarcane. Subsequently, the exon-intron organization structure and conserved motif arrangemeCurrent issues in molecular biology1632-1651https://www.ebi.ac.uk/biostudies/studies/S-EPMC8929030biostudies-literatureGenome-Wide Identification of LRR-RLK Family in <i>Saccharum</i> and Expression Analysis in Response to Biotic and Abiotic Stress.PMC8929030Xu LLu GXu FAhmad WCheng WSu YWang ZfalseGenome-Wide Identification of LRR-RLK Family in <i>Saccharum</i> and Expression Analysis in Response to Biotic and Abiotic Stress.The leucine-rich repeat receptor-like protein kinase (LRR-RLK) gene family is the largest family of the receptor-like protein kinases (RLKs) superfamily in higher plants, which is involved in regulating the plant growth and development, stress responses, signal transduction and so on.
