Different pollinators can exert different selective pressures on floral traits, depending on how they fit with flowers, which should be reflected in the patterns of variation and covariation of traits. Surprisingly, empirical evidence in support of this view is scarce. Here, we have studied whether the variation observed in floral phenotypic integration and covariation of traits in Narcissus sp...
Glycogen synthase kinase-3β (GSK-3β) is a multifunctional serine/threonine protein kinase that was originally identified as an enzyme involved in the control of glycogen metabolism. It plays a key role in diverse physiological processes including metabolism, the cell cycle, and gene expression by regulating a wide variety of well-known substances like glycogen synthase, tau-protein, and β-caten...
Geophytes are plants of high biological diversity that depends to a great extent on the growing process. Based what is stated, any new method production Narcissus L. has decisive effect its production. The aim study determine if it possible achieve better economic-agricultural results with method/form plant (Narcissus L., Amaryllidaceae). Under conditions Pannonian environment two methods/forms...

Twenty-one alkaloids and related compounds were found in Sternbergia colchiciflora (Amaryllidaceae), a hitherto not studied plant species. Twenty of them were detected by GC-MS in the crude extracts of this plant species. Ten alkaloids were isolated and their structures confirmed by NMR, MS and CD measurements. Many of the compounds found in this species, such as lycorine, tazettine, haemanthid...
Eithea lagopaivae Campos-Rocha & Dutilh, sp. nov. is described as the second species of the formerly monotypic genus Eithea. It is characterized by a one flowered inflorescence, completely hollow scape, white or lightly magenta-striated flower that is enclosed by spathe bracts fused for more than the lower fifth of its length. Comments on its range, habitat, phenology, as well as photographs an...
The AChE inhibitory activity of alkaloid extracts and compounds has been in the focus research on plants Amaryllidoideae subfamily since approval galanthamine 2001 by FDA for treatment mild to moderate Alzheimer's disease. A small fraction huge biodiversity producing Amaryllidaceae alkaloids studied as a source inhibitors. Less than 20% known have tested vitro their ability inhibit AChE. Galant...
در این پژوهش، ویژگیهای اپیدرم و برش مقطع عرضی برگ در 17 گونه از جنس Alliumمورد بررسی قرار گرفته است. در برش عرضی قسمت میانی برگ و مطالعه اپیدرم ویژگیهایی از قبیل؛ وجود رگبرگ میانی برجسته (دارای دو بازو و یک بخش میانی باشد)، وجود غلاف آوندی، وجود سلولهای اسکلرانشیمی، تعداد لایههای سلولهای اسکلرانشیمی، طول متاگزیلم، تعداد دستجات آوندی، اتصال یک دسته آوندی به دسته آوندی دیگر، طول پارانشیم نرد...
