We isolated a rice T-DNA tagging line, in which T-DNA was inserted into the sixth intron of OsP5CS2. This gene encodes for a protein that is highly homologous to 1-pyrroline-5-carboxylate synthetase (P5CS), a proline biosynthesis enzyme. The T-DNA contained the promoterless gus gene, allowing generation of a gene fusion between OsP5CS2 and gus. Therefore, the expression pattern of OsP5CS2 could...

Iron-sulfur cluster biosynthesis involving the nitrogen fixation (Nif) proteins has been proposed as a general mechanism acting in various organisms. NifU-like protein may play an important role in protecting plants against abiotic and biotic stresses. An iron-sulfur cluster scaffold protein gene, IbNFU1, was isolated from a salt-tolerant sweetpotato (Ipomoea batatas (L.) Lam.) line LM79 in our...

Petunias (Petunia hybrida cv. 'Mitchell') accumulate free proline (Pro) under drought-stress conditions. It is therefore believed that Pro acts as an osmoprotectant in plants subjected to drought conditions. Petunia plants were transformed by Delta(1)-pyrroline-5-carboxylate synthetase genes (AtP5CS from Arabidopsis thaliana L. or OsP5CS from Oryza sativa L.). The transgenic plants accumulated ...

It has been established that drought-responsive element binding (DREB) proteins correspond to transcription factors which play important regulatory roles in plant response to abiotic and biotic stresses. In this study, a novel cDNA encoding DREB transcription factor, designated StDREB1, was isolated from potato (Solanum tuberosum L.). This protein was classified in the A-4 group of DREB subfami...

Plants encounter various stresses such as drought and salinity which adversely affect growth, development and crop productivity. The expression of the genes Delta -1- pyr-roline – 5 - carboxylate synthetase (P5CS) and Betaine aldehyde dehydrogenase (BADH) extends throughout various protec-tive mechanisms in plants and allows them to adapt to unfavorable environmental condi-tions. P5CS and BADH ...

Autosomal recessive cutis laxa type 3A is caused by mutations in ALDH18A1, a gene encoding the mitochondrial enzyme Δ(1)-pyrroline-5-carboxylate synthase (P5CS). It is a rare disorder with only six pathogenic mutations and 10 affected individuals from five families previously described in the literature. Here we report the identification of novel compound heterozygous missense mutations in two ...

The objective of the present work was to determine what impact extremely high nitrogen dosages would have on proline metabolism in order to use this amino acid as a bioindicator of N status of green bean plants (Phaseolus vulgaris L. cv. Strike). In this effort, we identified the most favourable pathway of proline synthesis under our experimental conditions. The N was applied to the nutrient so...

An interesting observation, reported for transgenic plants that have been engineered to overproduce osmolytes, is that they often exhibit impaired growth in the absence of stress. As growth reduction and accumulation of osmolytes both typically result from adaptation, we hypothesized that growth reduction may actually result from osmolyte accumulation. To examine this possibility more closely, ...

Recent studies have shown that pyrroline 5-carboxylate, the intermediate in the interconversions of proline, ornithine, and glutamate, can regulate the metabolism of erythrocytes. We now report that the formation of 5-phosphoribosyl 1-pyrophosphate (PP-Rib-P) was markedly stimulated by pyrroline 5-carboxylate in intact red cells. The production of PP-Rib-P is an important point of regulation in...
