Abstract
Background
Receptor-like kinase (RLK), as a phosphotransferase, is widely involved in plant growth and development and stress response. RLK in plants could be divided into different types according to the sequence characteristics. LRK10 kinase is a subfamily of RLKs and has been considered to be associated with plant disease resistance. LRK10 is differentially expressed during ABA-mediated grape berry ripening, showing its possibility with plant development.
Results
To explore the relationship between VvLRK10L genes and plant development, 4 VvLRK10L genes were cloned, and their conserved domains, subcellular localization and promoter activity were analyzed. VvLRK10L-16 and VvLRK10L-42 were localized to the plasma membrane. GA3 and ABA treatments enhanced their promoter activity, respectively, and the overexpression of these two genes promoted plant growth.
Conclusions
VvLRK10L-16 and VvLRK10L-42 are located in the plasma membrane, which can respond to hormone signals and promote the development of Arabidopsis thaliana.
