Qualitative analysis specific to chi11 gene and its functionality. (A) Gel diffusion assay- 150 μg crude protein pipetted into individual wells in the 1.5% agarose with 0.4% colloidal chitin gel plate. After incubation, lytic zones visualized by UV transillumination. #Not applicable for investigation. (B) A significant difference (∗∗∗P = < 0.001) in mean zone area (calculated from three replicates) between transgenic and WT plants observed. (C) Fold change of developed zone area in transgenic plants over WT represents a significant difference (∗∗∗P = < 0.001). (D) In-solution chitinase assay; 100 μg of total protein incubated with colloidal chitin and the resulting product measured at 530 nm. A significant difference (∗∗∗P = < 0.001) in OD values between transgenic and non-transgenic WT plant observed. One-way ANOVA was used to compare the means and differences between group means at P < 0.05 and Tukey’s multiple comparisons taken under consideration by using Graphpad Prism 6 software. Here specific individual plants are the representatives of the three transgenic lines JBC1, JBC2, and JBC3. A total of 10 biological replicates were analyzed from each transgenic line.
