A nuclear gene encoding mitochondrial proline dehydrogenase, an enzyme involved in proline metabolism, is upregulated by proline but downregulated by dehydration in Arabidopsis.


Proline is one of the most common compatible osmolytes in water-stressed plants. The accumulation of proline in dehydrated plants is caused both by the activation of proline biosynthesis and by the inactivation of proline degradation; a decrease in the level of accumulated proline in rehydrated plants is caused both by the inhibition of proline biosynthesis… (More)
