Morphology and number of glandular trichomes on tobacco stems. (a-c) Glandular trichomes of wild-type (WT), empty vector pCAMBIA2300 (2300) and overexpression of LaMYC4 transgenic plants (35S::LaMYC4) on stem surfaces. (d) Number of glandular trichomes on the stem surfaces of wild-type (WT), empty vector pCAMBIA2300 (2300) and overexpression of LaMYC4 transgenic plants (35S::LaMYC4). The type of trichome was glandular trichomes. A total of five plants were selected, and three completely randomized fields of view were chosen for examination. Red arrows indicate glandular trichomes. The bars represent the mean values (± SD), calculated from three to four scanning-electron micrographs of stems from different plants. Standard errors are indicated as vertical lines on the top of each bar, and bars annotated with different letters were significantly different according to Fisher’s LSD test (P < 0.05) after ANOVA
