Oh, S.-K., Jang, H. A., Kim, J., Choi, D., Park, Y.-I. and Kwon, S.-Y. 2014. Expression of cucumber LOX genes in response to powdery mildew and defense-related signal molecules. Can. J. Plant Sci. 94: 845-850. The cucumber genome contains 23 lipoxygenase (LOX) genes. The expression of seven type-I and six type-II LOX genes was induced when cucumber leaves were challenged with Sphaerotheca fuliginea and treated with salicylic acid, methyl jasmonate, and abscisic acid. These 13 CsLOX genes were differentially regulated during biotic and abiotic stresses.
