Salinity is a main and common stress which decreases the amount of agriculture products and natural plants in many areas of the world. In this study, the effect of salt stress on three varieties of Lotus corniculatus 'Karaj', 'Jolfa', and 'Ardabil' was investigated. Plants were cultured in hydroponic condition with four NaCl treatments (0, 50, 100, 150 mM). The amounts of proline, glycine betai...

abstract   aluminum is one of the most important heavy metals which not only can be easily absorbed by roots, but it also damages its normal function and blocks absorption of water and nutrients. according to this fact that sunflower has been widely used in industry, this study investigates the effects of aluminum toxicity on biochemical factors in two sunflower varieties including sirena (tole...

The impact of water stress on antioxidant enzyme activities, proline, soluble sugars, and carotenoids contents found in Digitaria commutata Cenchrus ciliaris plants was investigated. Two different watering regimes were used over a period three months. Water decreased total chlorophyll content plants, but increased content. Interestingly, no change observed the quantum yield PSII photochemistry ...

Sugars act as signaling molecules, whose signal transduction pathways may lead to the activation or inactivation of gene expression. Whole-genome transcript profiling reveals that the flavonoid and anthocyanin biosynthetic pathways are strongly up-regulated following sucrose (Suc) treatment. Besides mRNA accumulation, Suc affects both flavonoid and anthocyanin contents. We investigated the effe...

Inorganic phosphate (Pi) starvation is an important abiotic constraint that affects plant cellular homeostasis, especially in tropical regions with high acidic soil and less solubilizable Pi. In the current work, oil palm seedlings were hydroponically maintained under optimal Pi-supply no conditions for 14 days, metabolites measured by gas chromatography–mass spectrometry (GC–MS), from leaves r...

Hemicelluloses are the earth's second most abundant structural polymers, found in lignocellulosic biomass. Efficient enzymatic depolymerization of xylans by cleaving their β-(1 → 4)-glycosidic bonds to produce soluble sugars is instrumental to the cost-effective production of liquid biofuels. Here we show that the multi-scale two-phase process of enzymatic hydrolysis of amorphous hemicelluloses...

The biochemical, phytochemical and antioxidant composition of root, stem, leaves and seeds of Cichorium intybus L was determined. A statistically significant difference (p>0.05) was observed among different parts of Cichorium intybus regarding the biochemical, phytochemical and antioxidant composition. The leaves were found to possess comparatively higher values of total sugars non-reducing sug...

Compared to simple sugars, complex carbohydrates have been assumed invisible to taste. However, two recent studies proposed that there may be a perceivable taste quality elicited by complex carbohydrates independent of sweet taste. There is precedent with behavioural studies demonstrating that rats are very attracted to complex carbohydrates, and that complex carbohydrates are preferred to simp...

The nutrient concentration of most crops depends on factors such as amount water, growing environment, sunlight, and soil types. However, the influencing African horned cucumber fruit are not yet known. objective study was to determine effect different water stress levels, types, environments fruit. Freeze-dried samples were used in quantification β-carotene total soluble sugars. results demons...

abstract the present research was done to evaluate proline, proteins and sugars of flower buds of pistachio trees during phonological stages. this study was conducted using a split-plot design with three replications considered time as main factor (5 stages) and cultivars (ahmad-aghaee, ouhadi, kaleh-ghochi and akbari) as secondary factor. the experiment was conducted at ferdowsi university of ...
