Accumulation of heavy metals in the soil causes a significant impact on biological processes plants. In present study, bioaccumulation copper (Cu) growth and biochemical constituents seedlings Casuarina equisetifolia was assessed. The results showed that C. is hyper-accumulator Cu. roots Equisetifolia significantly accumulated (p< 0.05) greater levels Cu than stem leaves. Similarly, exposed ...

The effects of wilting on the fate of proline and on the rates of nonprotein proline formation and utilization have been determined in excised bean leaves. Wilting did not alter the fate of exogenously added (14)C-l-proline (2 mm) in either non-starved leaves (from plants previously in the light) or starved leaves (from plants previously in the dark). The fate of proline in nonstarved leaves wa...

Oligofructans represent one of the most important groups of sucrose-derived water-soluble carbohydrates in the plant kingdom. In cereals, oligofructans accumulate in above ground parts of the plants (stems, leaves, seeds) and their biosynthesis leads to the formation of both types of glycosidic linkages [β(2,1); β(2,6)-fructans] or mixed patterns. In recent studies, tissue- and development- spe...

Development of cotton (Gossypium hirsutum L.) squares (i.e. floral buds with bracts) is fundamental for yield formation. A 2-year field study was conducted to determine dry weight (DW) accumulations of cotton leaves, floral bracts and floral buds, and the changes in concentrations of non-structural carbohydrates (hexoses, sucrose and starch) in these tissues during square ontogeny as affected b...

Leaf exchange is an abrupt phenological event that drastically modifies the morphology and physiology of the aerial portion of the plant. We examined if water and osmolyte differences between old leaves and new organs trigger leaf exchange, and whether the differences are closely linked to the resource resorption process in senescing leaves. We monitored concentrations of osmolyte, water, non-s...

Cassava is one of the most important root crops as a reliable source of food and carbohydrates. Carbohydrate metabolism and starch accumulation in cassava storage root is a cascade process that includes large amounts of proteins and cofactors. Here, comparative proteomics were conducted in cassava root at nine developmental stages. A total of 154 identified proteins were found to be differentia...

In celery (Apium graveolens L.), the two major translocated carbohydrates are sucrose and the acyclic polyol mannitol. Their metabolism, however, is different and their specific functions are uncertain. To compare their roles in carbon partitioning and sink-source transitions, developmental changes in (14)CO(2) labeling, pool sizes, and key enzyme activities in leaf tissues were examined. The p...

Introduction: In our modern era, life style of human being changes and updates every day that may affect their health status. There is an incredible expectation that natural origin drugs lack undesirable effects not like synthetic drugs, though have the same potency and efficacy. No scientific data is available about the antianxiety properties of Delphinium denudatum root and Amaranthus spinosu...

a study of physiological responses of different wheat cultivars to saline conditions can lead to an identification of the main mechanisms in salt tolerance. seven bread wheat cultivars differing in salt tolerance with varying ability of sodium accumulation in their different tissues were employed to assess ion distribution and sodium accumulation under saline conditions. ion distribution and na...

the effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (brassica napus l.) grown in the hoagland solution. the growth of treated plants was inhibited under lead stress. lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgl-1 of pb. hyola308 cultivar showed low biomass...
