Cystatins are protein inhibitors of cystein proteinases belonging to the papain family. In cowpea, cystatin‐like polypeptides and a cDNA have been identified from seeds metabolic functions attributed them. This paper describes VuC1 , new cystatin isolated cowpea leaves ( Vigna unguiculata (L.) Walp.). Sequence analysis revealed multicystatin structure with two domains. The recombinant VUC1 (rVUC1) was expressed in an heterologous expression system purified apparent homogeneity. It appeared...
Abstract Screening of a wheat (Triticum aestivum) cDNA library for starch-branching enzyme I (SBEI) genes combined with 5′-rapid amplification ends resulted in isolation 4,563-bp composite cDNA, Sbe1c. Based on sequence alignment to characterized SBEI clones isolated from plants, the SBEIc predicted was produced transit peptide directing polypeptide into plastids. Furthermore, mature form much larger (152 kD) than previously plant (80–100 and contained partial duplication sequences. The...
The presence of aluminum (Al) in acidic soils is a major abiotic stress limiting the production cultivated plants. Cell membranes are main targets environmental stresses and there growing evidence for involvement membrane lipids plant adaptation. aim this study was to evaluate mid-long effects Al on lipid content composition roots shoots rice plants grown under hydroponic conditions. Four cultivars were compared: two acknowledged as Al-resistant (Koshihikari) Al-sensitive (Kasalath),...
Leaf senescence is characterised by a massive degradation of proteins in order to recycle nitrogen other parts the plant, such as younger leaves or developing grain/seed. Protein during leaf highly regulated process and it suggested that be degraded are marked an oxidative modification (carbonylation) makes them more susceptible proteolysis. However, there yet no evidence increase protein carbonylation level natural senescence. The aim our study was thus monitor flag field-grown winter wheat...
Basal phosphoinositide-dependent phospholipase C (PI-PLC) activity controls gene expression in Arabidopsis suspension cells and seedlings. PI-PLC catalyzes the production of phosphorylated inositol diacylglycerol (DAG) from phosphoinositides. It is not known how regulates transcriptome although action DAG-kinase (DGK) on DAG immediately downstream responsible for some regulation. We previously established a list genes whose affected presence inhibitors. Here this was used as signature...
The interactive effects of drought and ozone on the physiology leaf membrane lipid content, composition metabolism cowpea (Vigna unguiculata (L.) Walp.) were investigated in two cultivars (EPACE-1 IT83-D) grown under controlled conditions. treatment (three-week water deprivation) did not cause injury but restricted growth through stomatal closure. In contrast, short-term (130 ppb 12 h daily during 14 day) had a limited impact at whole-plant level caused injury, hydrogen peroxide accumulation...
An in vitro culture system is useful to study grain development under defined conditions minimize confounding effects associated with whole plant studies and metabolite movement into the developing grains. The objective of this was monitor expression patterns carbohydrate metabolism genes during an wheat spike system. Immature spikes were cultured prior anthesis, grains collected at various days postanthesis (DPA). Grains from showed maximum starch metabolic by 10 DPA, a rapid decline...
Drought is the main climatic limitation to coconut palm (Cocos nucifera L.) production. To identify early screening parameters for drought resistance, physiological responses water deficit were investigated first time using containerized young plants grown outside. Three varieties studied: 'West Coast Tall' (drought avoiding), 'Malayan Yellow Dwarf' susceptible), and their progeny, hybrid 'PB 121' resistant). Leaf status (relative content, leaf potential) gas exchange (stomatal conductance...
Monoculture and intensive use of pesticides have reduced the biodiversity agrosystems increased imbalance between pathogenic beneficial organisms. In past, pineapple pests were generally controlled by pesticides, but today very few are authorized. fragile environments like in French Antilles, there is a growing public demand for prevention environmental risk. Agricultural research responding designing new cropping systems based on ecological intensification farming practices alternative ways...
