Abstract Abstract Abstract LRR-RLKs plays an important role in multiple signal transduction in plant. One full-length cDNA encoding a LRR-RLKs homologue was isolated from maize through in silico cloning and named as ZmLRRPK1 ( GenBank accession:EU873320 ). The predicted ZmLRRPK1 protein has 594 amino acids with an estimated molecular mass of 66kDa and an isoelectric point of 5.42. ZmLRRPK1 has the typical domain of LRR-RLKs. RT-PCR analysis indicated that ZmLRRPK1 expression was induced by ABA, mannitol and salt in coleoptiles of maize and kept high level during 24 hours.
