Analysis of hdg2 Trichome Cell Wall Mutant.

(A–C) Stereomicrographs of trichomes from hdg2-2 mutant, wild-type, and rescued hdg2-2, respectively.

(D–F) SEM of wild-type, hdg2-2, and wild-type transformed with pEGAD MYB5:GFP–cHDG2 transgene showing co-suppressed hdg2-like mutant papillae phenotype, respectively.

(G–I) Higher magnification of trichomes shown in (D–F).

(J, K) Elemental analysis of wild-type and hdg2-2 trichome papillae.

(L, M) TEM of cross-section through branch of wild-type and hdg2-2 mutant trichomes.

(N) Localization of GFP–HDG2 fusion protein in wild-type plant transformed with the pEGAD MYB5:GFP–cHDG2 transgene.

Bars in (A–F)  =  100 μm; (G–J)  =  1 μm; (L, M)  =  0.5 μm.
