abstract in order to study the effects of salinity and silicon application on biomass of leaves and root of purslane (portulaca oleracea l.), a greenhouse experiment was conducted at research greenhouse of ferdowsi university of mashhad using completely randomized desgin with three replications. employed two factors consisted of three levels of salinity using nacl (0.6, 11, 22 ds/m) and two lev...

During the last decade, the paradigm that low toxicant doses often have stimulatory effects on plants has become widely accepted. At the same time, low toxicant doses of metal salts have been observed to inhibit the growth of the most vigorous seedlings of a population in vitro, although mean plant size has remained unaffected. We hypothesized that this kind of selective low-dose toxicity is no...

Etiolated spinach (Spinacia oleracea L. var Winter Giant) seedlings show a residual photosynthetic fructose-1,6-bisphosphatase activity, which sharply rises under illumination. This increase in activity is due to a light-induced de novo synthesis, as it has been demonstrated by enzyme labeling experiments with (2)H(2)O and [(35)S]methionine. The rise of bisphosphatase activity under illuminatio...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the COVID-19 pandemic that infects humans and attacks body's immune system. The purpose of study was to identify potential bioactive compounds in purslane (Portulaca oleracea L.) star anise (Illicium verum Hook) via a dual inhibitor mechanism against SARS-CoV-2 proteases with an silico approach. samples were obtained from PubCh...

Three fungi newly intercepted from importing plants were identified in 2004. They were Ascochyta chrysanthemi on Lactuca sativa from China, A. spinaciicola on Spinacia oleracea from Denmark, and Leptosphaerulina australis on Brassica oleracea var. capitata from China. The characters of these fungi were described and illustrated.
