We screened for α-glucosidase inhibitors from 12 traditional medicinal plants used for the treatment of diabetes. Potent α-glucosidase inhibitory activity was found in aqueous extract of Psidium guajava leaves and Syzygium cumini Linn seed extract. Active principles inhibiting α-glucosidase were isolated and identified as apigenin 7O-glucoside in the S.cumini Linn seed extract and Dihydro-3,3’,...

Background & Aim: Persian shallot (Allium hirtifolium Boiss) with common name of "Musir" is one of the endemic medicinal plants in Iran. Leaves and bulbs with antibacterial, antifungal, anticancer, anti-diabetes and anti-obesity effects are edible parts of this plant. The tissue culture is an influential method to multiply plant productions in order to meet demands of ...

Effects of water stress and foliar boron (FB) application on soybean (Glycine max (L) Merr.) seed composition and nitrogen metabolism have not been well investigated. Therefore, the objective of this study was to investigate the effects of water stress and FB on seed protein, oil, fatty acids, nitrate reductase activity (NRA), and nitrogenase activity (NA). A repeated greenhouse experiment was ...

Limited information is available on the effects of foliar boron (B) application on soybean seed composition. The objective of this research was to investigate the effects of foliar B on seed composition (protein, oil, fatty acids, and sugars). Our hypothesis was that since B is involved in nitrogen and carbon metabolism, it may impact seed composition. A repeated greenhouse experiment was condu...

Plant somatic cells have the remarkable ability to regenerate an entire organism. Many species in the genus Kalanchoë, known as "mother of thousands," develop plantlets on the leaf margins. Using key regulators of organogenesis (STM) and embryogenesis (LEC1 and FUS3) processes, we analyzed asexual reproduction in Kalanchoë leaves. Suppression of STM abolished the ability to make plantlets. Here...

Responses to prolonged low-temperature treatment of imbibed seeds (vernalization) were examined in barley (Hordeum vulgare). These occurred in two phases: the perception of prolonged cold, which occurred gradually at low temperatures, and the acceleration of reproductive development, which occurred after vernalization. Expression of the VERNALIZATION1 gene (HvVRN1) increased gradually in germin...

Enhancing nutrient density in legume seeds is one of several strategies being explored to improve the nutritional quality of the food supply. In order to develop crop varieties with increased seed mineral concentration, a more detailed understanding of mineral translocation within the plant is required. By studying mineral accumulation in different organs within genetically diverse members of t...
