Figure 2From: Overexpression of constitutively active mitogen activated protein kinase kinase 6 enhances tolerance to salt stress in riceAnalyzing salt tolerance of OsMKK6EEoverexpressed transgenic plants. (A) Leaf disc assay, the phenotypic appearance of the transgenic leaf segments as compared to wild type (control) leaves. (B) Percentage chlorophyll retention of transgenic leaves. The asterisks represent the significant difference in cholorphyll retention compared with wild type (WT) plants, (*) P < 0.05, (**) P < 0.01.Back to article page
