Plant lipoxygenases (LOXs), a kind of non-heme iron-containing dioxygenases, participate plant physiological activities (especially in response to biotic and abiotic stresses) through oxidizing various lipids. However, there was few investigations on LOXs in foxtail millet (). In this study, we identified the gene family in foxtail millet, and divided the total 12 members into three sub-families on the basis of their phylogenetic relationships. Under salt and drought stress, genes showed different expression patterns. Among them, only showed up-regulated expression in Yugu1 (YG1) and Qinhuang2 (QH2), two stress-tolerant varieties, indicating that may play an important role in responses to abiotic stress. Our research provides a basis for further investigation of the role of genes in the adaptation to abiotic stresses and other possible biological functions in foxtail millet.

植物脂氧合酶（LOXs）是一类含非血红素铁的双加氧酶，通过氧化各种脂质参与植物生理活动（特别是对生物和非生物胁迫的响应）。然而，关于谷子中脂氧合酶的研究很少。在本研究中，我们鉴定了谷子中的基因家族，并根据其系统发育关系将总共 12 个成员分为三个亚家族。在盐胁迫和干旱胁迫下，基因表现出不同的表达模式。其中，只有在两个耐胁迫品种豫谷 1 号（YG1）和秦皇 2 号（QH2）中表现出上调表达，表明可能在非生物胁迫响应中起重要作用。我们的研究为进一步研究基因在谷子适应非生物胁迫中的作用以及其他可能的生物学功能提供了基础。
