Membrane traffic contributes to plant growth and development. However, the functional significance of SNARE proteins involved in membrane fusion of the early secretory pathway has not been explored with respect to plant development. Here we analyze the Arabidopsis v-SNARE SEC22.

Mutations in four Arabidopsis genes collectively called the PILZ group result in lethal embryos that consist of one or a few grossly enlarged cells. The mutant embryos lack microtubules but not actin filaments.
