The import-export transition in sugar beet leaves (Beta vulgaris) occurred at 40 to 50% leaf expansion and was characterized by loss in assimilate import and increase in photosynthesis. The metabolism and partitioning of assimilated and translocated C were determined during leaf development and related to the translocation status of the leaf. The import stage was characterized by C derived from...

Little is known about the nature of floral inductive cues in day-neutral plants that are insensitive to photoperiod variations and, therefore, rely on endogenous signals to initiate reproductive growth. The INDETERMINATE1 (ID1) transcription factor is a key regulator of the transition to flowering in day-neutral maize. The ID1 gene is expressed exclusively in developing leaves, where it control...

background & aim: applications of synthetic antioxidant in food have side effects. in present study, the antioxidant potential of morus alba leaves, as natural antioxidant, was screened with cupric ion reducing assay (cuprac assay) and inhibition of lipid peroxidation. the aim of this study was to determine the total antioxidant activity of morus alba leaves. martial & methods: the fir...

plants are the most common bioindicatorsused in air quality biomonitoring studies because they are immobile and they have more sensitive to the most prevalent air pollutants than humans and animals. to identify the concentrations and sources of heavy metals in ornamental plants of isfahan landscape, samples of leaves and soil around pinuseldarica and nerium oleander were collected at different ...

Short term experiments were conducted with vegetative soybean plants (Glycine max L. Merr. ;Ransom' or ;Arksoy') to determine whether sourcesink manipulations, which rapidly changed the ;demand' for sucrose and partitioning of photosynthetically fixed carbon into starch, were associated with alterations in activities of sucrose-P synthase and/or cytoplasmic fructose-1,6-bisphosphatase in leaf e...
