Proline: a multifunctional amino acid.
Proline accumulates in many plant species in response to environmental stress. Although much is now known about proline metabolism, some aspects of its biological functions are still unclear. Here,Expand

How reactive oxygen species and proline face stress together.
Reactive oxygen species (ROS) are continuously generated as a consequence of plant metabolic processes due to incomplete reduction of O2. Previously considered to be only toxic by-products ofExpand

Transcriptional regulation of proline biosynthesis in Medicago truncatula reveals developmental and environmental specific features.
The model legume plant Medicago truncatula accumulates free proline in response to hyperosmotic stress as do many other organisms. In order to analyse the transcriptional regulation of prolineExpand

Diversity, distribution and roles of osmoprotective compounds accumulated in halophytes under abiotic stress.
BACKGROUND AND AIMS Osmolytes are low-molecular-weight organic solutes, a broad group that encompasses a variety of compounds such as amino acids, tertiary sulphonium and quaternary ammoniumExpand

Plant cyclins: a unified nomenclature for plant A-, B- and D-type cyclins based on sequence organization
The comparative analysis of a large number of plant cyclins of the A/B family has recently revealed that plants possess two distinct B-type groups and three distinct A-type groups of cyclins [1].Expand

Abscisic acid-independent and abscisic acid-dependent regulation of proline biosynthesis following cold and osmotic stresses in Arabidopsis thaliana
Abstract The role of the phytohormone abscisic acid (ABA) in the regulation of proline synthesis was investigated by following the expression of the At-P5S and At-P5R proline biosynthesis genes inExpand

Metabolome and water homeostasis analysis of Thellungiella salsuginea suggests that dehydration tolerance is a key response to osmotic stress in this halophyte.
Thellungiella salsuginea, a Brassicaceae species closely related to Arabidopsis thaliana, is tolerant to high salinity. The two species were compared under conditions of osmotic stress to assess theExpand

Phospholipase D Is a Negative Regulator of Proline Biosynthesis in Arabidopsis thaliana*
Accumulation of proline has been observed in a large number of plant species in response to drought and salt stresses, suggesting a key role of this amino acid in plant stress adaptation. UpstreamExpand

Characterization of an Arabidopsis thaliana receptor-like protein kinase gene activated by oxidative stress and pathogen attack.
An Arabidopsis thaliana cDNA clone that encodes a putative receptor-like protein kinase gene (At-RLK3) was characterized. The deduced 667-amino acid protein consists of an amino-terminal signalExpand

Mutations in the Hyperosmotic Stress-Responsive Mitochondrial BASIC AMINO ACID CARRIER2 Enhance Proline Accumulation in Arabidopsis1[C][W]
Mitochondrial carrier family proteins are diverse in their substrate specificity, organellar location, and gene expression. In Arabidopsis (Arabidopsis thaliana), 58 genes encode theseExpand
