| Summary: | 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 (<i>Setaria italica</i>). In this study, we identified the <i>LOX</i> 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, <i>LOX</i> genes showed different expression patterns. Among them, only <i>SiLOX7</i> showed up-regulated expression in Yugu1 (YG1) and Qinhuang2 (QH2), two stress-tolerant varieties, indicating that <i>SiLOX7</i> may play an important role in responses to abiotic stress. Our research provides a basis for further investigation of the role of <i>LOX</i> genes in the adaptation to abiotic stresses and other possible biological functions in foxtail millet.
