Fig. 2. Epidermal peel of wild-type adaxial blade and impressions of wild-type and mutant blade epidermises. (A) Wild-type epidermal tissue is characterized by a very regular pattern of specialized cells: macrohairs (mh), pricklehairs (ph), microhairs (mih), bulliform cells (bc), long cells (lc), silica cells (sc), and guard cells with associated subsidiary cells, which together make up stomatal complexes (st). (B) Macrohairs (white arrowhead) and bulliform cell rows (black arrowhead) are seen in the wild-type adaxial epidermis. In contrast, no macrohairs are seen in the wild-type abaxial epidermis (D). (C) Adaxial epidermis of Rolled leaf1-PB heterozygous mutant. (E) Abaxial epidermis of Rolled leaf1-PB heterozygous mutant. Arrow indicates macrohair.
