Autophagy is an evolutionary conserved process of bulk degradation and nutrient sequestration that occurs in all eukaryotic cells. Yet, in recent years, autophagy has also been shown to play a role in the specific degradation of individual proteins or protein aggregates as well as of damaged organelles. The process was initially discovered in yeast and has also been very well studied in mammals and,...
Proline-rich proteins (PRP) are cell wall and plasma membrane-anchored factors involved in cell wall maintenance and its stress-induced fortification. Here we compare the synthesis of P5C as the proline (Pro) precursor in the cytosol and chloroplast by an introduced alien system and evaluate correlation between PRP synthesis and free Pro accumulation in plants.We developed a Pro over-producing system...
Free proline accumulation is an innate response of many plants to osmotic stress. To characterize transcriptional regulation of the key proline cycle enzymes in alfalfa (Medicago sativa), two proline dehydrogenase (MsPDH) genes and a partial sequence of Δ 1 -pyrroline-5-carboxylate dehydrogenase (MsP5CDH) gene were identified and cloned. The two MsPDH genes share a high nucleotide sequence homology...
