Abstract
Budding yeast strains that produced the Arabidopsis thaliana protein CEF or its amino-terminal proline-rich domain were more tolerant to hydroperoxides. CEF is homologous to animal and yeast Sec24 proteins. These data suggest that CEF plays a protective role through protein transport during growth under pro-oxidant conditions.
Key words: Arabidopsis, oxidative stress, Sec24.
