Involvement of OsMKK6 in UV induced expression of genes of phytoalexin biosynthesis in rice leaves. Expressions of a OsKSL4, b OsCYP99A3, c OsMAS, d OsKSL7, e OsKSL8, and f OsKSL10 in OsMKK6^EE overexpression lines was checked by qRT-PCR. Expression levels were normalized against rice actin gene as an internal control and are shown relative to UV-B unexposed control. The relative level of each gene in control plants at time 0 was standardized as 1. Values are presented as the mean and the error bars indicate SD of three independent experiments.
