Abstract excerpt
The twn2 mutant of Arabidopsis exhibits a defect in early embryogenesis where, following one or two divisions of the zygote, the decendents of the apical cell arrest. The basal cells that normally give rise to the suspensor proliferate abnormally, giving rise to multiple embryos. A high proportion of the seeds fail to develop viable embryos, and those that do, contain a high proportion of partially or completely...
