SRA1 complements the trichome morphology defect of the hl mutant.

Light microscopy was used to assess the trichome morphology of WT, hl, and two complemented transgenic lines (SRA1-2 and SRA1-10). Photographs show the adaxial leaf surface (upper row), stem (middle row), and hypocotyl (lower row) of each genotype. Arrows indicate representative type I trichomes. Scale bars: 500 µm, adaxial leaf surface; 2mm, stems and hypocotyls. Three-week-old plants were used for all photographs. (This figure is available in color at JXB online.)
