Fig. 6: The beardless mutant of clary sage displays reduced glandular trichomes density and sclareol and linalyl acetate content.
From: Sclareol and linalyl acetate are produced by glandular trichomes through the MEP pathway
a–d Phenotype of the wild-type (WT) and beardless (bl) mutant. a, c Young stem; b, d calyx; scale bar: 4 mm. e, f Scanning electron microscopy of the WT (e) and beardless (f) calyx. Blue arrowheads indicate short capitate glandular trichomes, circles indicate long capitate glandular trichomes, dashed circles indicate peltate glandular trichomes. Scale bar: 300 µm. g Density of different trichome types at the surface of calyces from WT and beardless plants. Bars represent the mean ± SD (WT, n = 9; beardless mutant, n = 10). P peltate glandular trichomes, LC large capitate glandular trichomes, SC small capitate glandular trichomes, NGT nonglandular trichomes. h Sclareol and linalyl acetate content in the WT and beardless mutant plants. Bars represent the mean ± SD (WT, n = 18; beardless mutant, n = 12). Stars indicate the results of the Student’s t test (***p < 0.0001)
