Identification and expression analysis of LRR-RLK genes reveal their roles in plant development and stress responses in Kiwifruit (Actinidia chinensis).

ABSTRACT: As an important economic crop, the growth and development of kiwifruit are sensitive to environmental stresses, which can lead to reduced yield and quality. Leucine-rich repeat receptor-like kinases (LRR-RLKs) constitute one of the largest groups of receptor-like kinases and play crucial roles in regulating plant growth and development, as well as responses to biotic and abiotic stresses. In this study, 307 LRR-RLK genes were identified in the kiwifruit genome and grouped into 13 subclades. A comprehensive analysis was conducted, encompassing physiochemical properties, evolutionary relationships, gene structure, conserved motifs, gene family expansion, functional annotation, tissue-specific expression, and responses to stresses. Members within each subclade displayed analogous conserved mo
