Fig. 1. Phenotypes of the wild type (Ler), dyt1 mutant and
transgenic plants for complementation. (A) A Ler plant.
(B) A dyt1 plant, with very small siliques (arrows).
(C) A Ler flower. (D) A dyt1 flower.
(E) A flower of the dyt1 plant with the DYT1
transgene. (F) A wild-type anther, with viable pollen grains (stained).
(G) A dyt1 anther, no viable pollen. (H) An anther from
a dyt1 plant with the DYT1 transgene, with a large number of
viable pollen grains and some microspores (arrowheads). Scale bars: 10 mm in
A,B; 500 µm in C-E; 20 µm in F-H.
