Declined free proline dehydrogenase (proline catabolic enzyme) might be another reason of increased free proline accumulation (Sundaresan and Sudhakaran, 1995; Lee and Liu, 1999).
We analyzed P5CR1 enzymatic activity with a proline dehydrogenase assay (P5CR1 inverse reaction).
Proline accumulation in the leaves of plants exposed to drought stress is not only associated with an increased expression of the p5cs gene but also with the decreased expression of proline dehydrogenase genes (PDH) coding for the enzymes of proline degradation (MILLER et al., 2005).
Another possible explanation might be that the proline dehydrogenase genes (PDH), which code for the enzymes responsible for proline degradation, are dissimilarly expressed in different plant organs.
Oxidative degradation of proline to glutamate is carried out in the mitochondria by sequential actions of proline dehydrogenase (ProDH) and P5C-dehydrogenase (P5C-DH) [65].
Proline Dehydrogenase (ProDH) Proline dehydrogenase activity was assayed according to the method of Reno and Splittstoesser [58].
