Abstract

Lipoxygenases (LOX) play pivotal roles in plant resistance to stresses. However, no study has been conducted on LOX gene identification at the whole genome scale in rose (Rosa chinensis). In this study, a total of 17 RcLOX members were identified in the rose genome. The members could be classified into three groups: 9-LOX, Type I 13-LOX, and Type II 13-LOX. Similar gene structures and protein domains can be found in RcLOX members. The RcLOX genes were spread among all seven chromosomes, with unbalanced distributions, and several tandem and proximal duplication events were found among RcLOX members. Expressions of the RcLOX genes were tissue-specific, while every RcLOX gene could be detected in at least one tissue. The expression levels of most RcLOX genes could be up-regulated by aphid infestation, suggesting potential roles in aphid resistance. Our study offers a systematic analysis of the RcLOX genes in rose, providing useful information not only for further gene cloning and functional exploration but also for the study of aphid resistance.
