When the seed coat forms from only one layer, it is also called the testa, though not all such testae are homologous from one species to the next.
The seeds had brittle white testae and tiny white embryos (less than 0.1 mm diameter).
The molecular data presented here are consistent with anatomical and biochemical differences between the wild-type and the mutant testae.
