Proline (Pro) is a versatile metabolite playing a role in the protection of plants against environmental stresses. To gain a deeper understanding of the regulation of Pro metabolism under predicted future climate conditions, including drought stress, elevated temperature and CO2 , we combined measurements in contrasting grassland species (two grasses and two legumes) at multiple organisational ...

Mature fruit of grapevine (Vitis vinifera) contains unusually high levels of free proline (Pro; up to 24 micromol or 2.8 mg/g fresh weight). Pro accumulation does not occur uniformly throughout berry development but only during the last 4 to 6 weeks of ripening when both berry growth and net protein accumulation have ceased. In contrast, the steady-state levels of both the mRNA encoding V. vini...

The TIFY family is a novel plant-specific protein family, and is characterized by a conserved TIFY motif (TIFF/YXG). Our previous studies indicated the potential roles of TIFY10/11 proteins in plant responses to alkaline stress. In the current study, we focused on the regulatory roles and possible physiological and molecular basis of the TIFY10 proteins in plant responses to alkaline stress. We...

Our containment trials have established cold tolerance in Nicotiana tabacum osmotin (Nt Osm) transgenic tomato (Solanum lycopersicum L. cv. Pusa Ruby). Though, the stress tolerance mechanisms have been studied at physio-biochemical levels, molecular mechanisms underlying the tolerant response are still not well studied. Therefore, quantitative transcript expression of Osmotin and other stress r...

Abstract Soil salinisation is an important factor limiting the cultivation and distribution of Prunus mume . Therefore, identifying regulation mechanism salt tolerance P. will promote its molecular breeding. In this study, garden tree species ‘Meiren’ was investigated, with a soil NaCl content (w/w) 0.3%. Photosynthetic gas exchange parameters, relative electrical conductivity, malondialdehyde,...

Physiological, metabolic, and genetic changes produced by two plant growth promoting rhizobacteria (PGPR) Pseudomonas sp. (internal code of the laboratory: N 5.12 21.24) inoculated in tomato plants subjected to moderate water stress (10% polyethylene glycol-6000; PEG) were studied. Photosynthesis efficiency, photosynthetic pigments, compatible osmolytes, reactive oxygen species (ROS) scavenging...

BackgroundThe ALDH18A1 gene is located at 10q24.1 and encodes delta-1-pyrroline-5-carboxylate synthetase (P5CS), a mitochondrial bifunctional enzyme that catalyzes the first two steps in de novo biosynthesis of proline, ornithine, citrulline, arginine. ALDH18A1-related disorders have been classified into four groups, such as autosomal dominant recessive hereditary spastic paraplegia (SPG9A SPG9...
