Proline is a proteogenic amino acid and accumulates both under stress and non-stress conditions as a beneficial solute in plants. Recent discoveries point out that proline plays an important role in plant growth and differentiation across life cycle. It is a key determinant of many cell wall proteins that plays important roles in plant development. The role of extensins, arabinogalactan proteins and hydroxyproline- and proline-rich proteins as important components of cell wall proteins that play pivotal roles in cell wall signal transduction cascades, plant development and stress tolerance is discussed in this review. Molecular insights are also provided here into the plausible roles of proline transporters modulating key events in plant development. In addition, the roles of proline during seed developmental transitions including storage protein synthesis are discussed.

Frontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

The response of proline metabolism to nitrogen deficiency in pods and seeds of French bean (Phaseolus vulgaris L cv Strike) plants

2001

The objective of the present work was to determine the impact of nitrogen de®ciency on proline metabolism in order to use this amino acid as a bioindicator of the N status of the pods and seeds of French bean (Phaseolus vulgaris L cv Strike) plants. We also identify the pathway of proline synthesis which is favoured under our experimental conditions. N was applied to the nutrient solution in the form of NH 4 NO 3 at 1.45 mM (N1), 2.90 mM (N2) and 5.80 mM (N3, optimal level). Our results indicate that N de®ciency is characterised by a decline in proline accumulation in both the pod and the seed, fundamentally because proline degradation is encouraged by stimulation of the enzyme proline dehydrogenase under these conditions. However, although the enzymes in charge of proline biosynthesis (ornithine-d-aminotransferase and D 1 -pyrroline-5-carboxylate synthetase) vary in behaviour depending on the N status, this amino acid appeared to be synthesised mainly by the enzyme ornithine-d-aminotransferase, suggesting predominance of the ornithine pathway over the glutamine pathway. Finally, under our experimental conditions, proline can be regarded as a good indicator of N de®ciency, particularly in the seeds of French bean plants.
