SCAR3 Can Substitute for SCAR2 during Trichome Morphogenesis.
Full-length SCAR2 and SCAR3 cDNAs were transformed into the scar2 background. Trichome morphogeneis was assayed in expanding leaves.
(A) Wild-type leaf with highly elongated trichomes.
(B) The expanding leaf of a scar2 mutant with distorted trichomes.
(C) The expanding leaf of a scar2 mutant transformed with 35S:SCAR2.
(D) The expanding leaf of a scar2 mutant transformed with 35S:SCAR3. Both wild-type trichomes (arrows) and trichomes with a weak distorted phenotype (arrowheads) are present.
