英文摘要: Abstract(#br)Receptor-like protein kinase (RLKs) plays pivotal roles in plant growth and development as well as stress responses. However, little is known about the function of RLKs in Nitotiana tobacum . In the present study, we present data on NtRLK5 , a novel RLK-like gene isolated from Hongda ( Nitotiana tobacum L.). Expression profile analysis revealed that NtRLK5 was strongly induced by drought and salt stresses. Transient expression of NtRLK5-GFP fusion protein in protoplast showed that NtRLK5 was localized to plasma membrane. Overexpression of NtRLK5 conferred enhanced drought tolerance in transgenic Arabidopsis plants, which was attributed to not only the lower malondialdehyde (MDA) and H 2 O 2 contents, but also the higher antioxidant enzymes activities. Moreover, the expression...
