Lipoxygenases (LOX) play pivotal roles in plant resistance to stresses. However, no study has been conducted on gene identification at the whole genome scale in rose (). 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 genes were spread among all seven chromosomes, with unbalanced distributions, and several tandem and proximal duplication events were found among members. Expressions of the genes were tissue-specific, while every gene could be detected in at least one tissue. The expression levels of most genes could be up-regulated by aphid infestation, suggesting potential roles in aphid resistance. Our study offers a systematic analysis of the genes in rose, providing useful information not only for further gene cloning and functional exploration but also for the study of aphid resistance.
脂氧合酶（LOX）在植物抵抗胁迫方面发挥着关键作用。然而，目前尚未在玫瑰（）中进行全基因组范围内的基因鉴定研究。在本研究中，在玫瑰基因组中鉴定出了总共 17 个 RcLOX 成员。这些成员可以分为三组：9-LOX、I 型 13-LOX 和 II 型 13-LOX。RcLOX 成员具有相似的基因结构和蛋白结构域。这些基因分布在所有的七个染色体上，分布不均，在成员之间发现了几个串联和近端重复事件。基因的表达具有组织特异性，而每个基因至少可以在一种组织中检测到。大多数基因的表达水平可以被蚜虫侵害上调，表明它们在抗蚜虫方面可能具有潜在作用。我们的研究对玫瑰中的基因进行了系统分析，不仅为进一步的基因克隆和功能探索提供了有用的信息，也为蚜虫抗性的研究提供了信息。
