Abstract excerpt

Proline (Pro) is one of the most widely distributed osmolytes in water-stressed plants. We previously isolated from Arabidopsis a gene encoding Pro dehydrogenase (ProDH), a mitochondrial enzyme involved in the first step of the conversion of Pro to glutamic acid. The ProDH gene in Arabidopsis is up-regulated by rehydration after dehydration but is down-regulated by dehydration. ProDH is also induced by L-Pro and...
