Altered levels of trichome branching in 3-week-old seedlings. The third and fourth leaves from 3-weeks-old seedlings of wild type and homozygous SALK_074069 ABI3MTA plants were examined for changes in their trichome phenotypes. Light micrographs of trichomes from plants with low m6A levels and from wild type plants (A). The low m6A plants are characterized by a higher proportion of trichomes with four or more branches. Trichomes from the abaxial side were analyzed for the third and fourth leaves from four wild type and four low m6A plants, each from different transgenic lines (554 and 521 trichomes respectively). Sixty-three percentage of trichomes from low methylation plants had four or more branches compared to just 24% in wild type (B). Error bars represent SD of the replicates.
