Plant roots respond to environmental stresses or the exogenous plant hormone abscisic acid (ABA) by undergoing marked physiological and morphological changes. We show here that PERK4, a gene that encodes a member of the Arabidopsis thaliana proline-rich extensin-like receptor kinase family, plays an

The gene coding for a new class of proteins rich in glycine and proline (GPRP) was cloned in Arabidopsis thaliana. In the protein sequence, five amino acids - glycine, proline, alanine, tyrosine and histidine - account for 79.4% of the total composition. The protein has two different glycine-rich

Azetidine-2-carboxylic acid, the 4-membered ring noranalogue of proline, is regularly used in the study of proline metabolism as well as the study of protein conformation. We prepared D,L-[2,3-3H]azetidine-2-carboxylic acid with an optimized 10% yield from commercially available

For the genetic potential of model systems such as Arabidopsis thaliana to be most effectively used to understand drought resistance, reliable and rapid protocols are needed for laboratory study of phenotypes relevant to stress responses in the field. Osmotic adjustment, the amount of additional

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. Upstream components of the proline biosynthesis signal transduction pathways are still poorly defined. We

The cell wall (CW) as a first line of defense against biotic and abiotic stresses is of primary importance in plant biology. The proteins associated with cell walls play a significant role in determining a plant's sustainability to adverse environmental conditions. In this work, the genes encoding

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 in Arabidopsis thaliana wild type, in an ABA-deficient aba1-1 mutant as well as in ABA-insensitive abi1-1 and

4-Hydroxyproline is found in collagens and collagen-like proteins in animals and in many glycoproteins in plants. Animal prolyl 4-hydroxylases (P4Hs) have been cloned and characterized from many sources, but no plant P4H has been cloned so far. We report here that the genome of Arabidopsis thaliana

The protein encoded by AtDHyPRP1 (DOUBLE HYBRID PROLINE-RICH PROTEIN 1) contains two tandem PRD-8CMs (proline-rich domain-eight cysteine motif) and represents a new type of HyPRPs (hybrid proline-rich proteins). Confocal microscopy to transgenic Arabidopsis plants revealed that AtDHyPRP1-GFP was

The isolation and characterization is reported of a cDNA for delta 1-pyrroline-5-carboxylate (P5C) synthetase (cAtP5CS), an enzyme involved in the biosynthesis of proline, from a cDNA library prepared from a dehydrated rosette plant of Arabidopsis thaliana. Southern blot analysis suggested that only

The relationships among photosynthetic acclimation, proline (Pro), soluble sugar (SS), and anthocyanin (An) accumulation in Arabidopsis thaliana leaves to the onset of drought stress (OnDS), mild (MiDS) and moderate drought stress (MoDS), were evaluated. As leaf water content (LWC) decreased,

Many plants accumulate proline, a compatible osmolyte, in response to various environmental stresses such as water deficit and salinity. In some stress responses, plants generate hydrogen peroxide (H2 O2 ) that mediates numerous physiological and biochemical processes. The aim was to study the

Plant adaptation to abiotic stresses such as drought and salinity involves complex regulatory processes. Deciphering the signaling components that are involved in stress signal transduction and cellular responses is of importance to understand how plants cope with salt stress. Accumulation of

The eco-physiology of salt tolerance, with an emphasis on K(+) nutrition and proline accumulation, was investigated in the halophyte Thellungiella halophila and in both wild type and eskimo-1 mutant of the glycophyte Arabidopsis thaliana, which differ in their proline accumulation capacity. Plants

Arabidopsis thaliana grows efficiently on GABA as the sole nitrogen source, thereby providing evidence for the existence of GABA transporters in plants. Heterologous complementation of a GABA uptake-deficient yeast mutant identified two previously known plant amino acid transporters, AAP3 and ProT2,
