Background and objectives: People interest in traditional medicine has increased recently; however, traditional herbal medicines should be transformed into modern forms of medicine to increase patient acceptance. In this investigation, a polyherbal traditional combination “Monzej-e-balgham” has been based on according to Iranian traditional medicine (ITM) manuscripts and its qu...

Phototropism, the bending response of plant organs to or away from a directional light source, is one of the best studied blue light responses in plants. Although phototropism has been studied for more than a century, recent advances have improved our understanding of the underlying signaling mechanisms involved. The NPH1 gene of Arabidopsis thaliana encodes a blue light-dependent autophosphory...

Here, we show that the polyamine spermidine plays a key role as a morphogenetic determinant during spermatid development in the water fern Marsilea vestita. Spermidine levels rise first in sterile jacket cells and then increase dramatically in spermatogenous cells as the spermatids mature. RNA interference and drug treatments were employed to deplete spermidine in the gametophyte at different s...

BACKGROUND Adiantum philippense (AP) is a pteridophyte that shows antihyperglycemic activity in vivo diabetic model, but the mechanism of action is unknown. OBJECTIVE AP was found to play a pivotal role in minimizing the high blood glucose in alloxan-induced diabetic rats. Simultaneously, it was observed that it could maintain the normal lipid profile even in diabetic condition. To investigat...

Across the tree of life, molecular phylogenetic studies often reveal surprising relationships between taxa with radically different morphologies that have long obscured their close affiliations. A spectacular botanical example is Rafflesia, a holoparasite that produces the largest flowers in the world, but that evolved from tiny-flowered ancestors within the Euphorbiaceae. Outside of parasitic ...

The aim of the present study was to investigate the anti-rheumatoid activity of secondary metabolites produced by endophytic mycobiota in Egypt. A total of 27 endophytic fungi were isolated from 10 dominant medicinal plant host species in Wadi Tala, Saint Katherine Protectorate, arid Sinai, Egypt. Of those taxa, seven isolates of Chaetomium globosum (CG1-CG7), being the most frequent taxon, wer...
