... A population of Silene vulgaris (Moench) Garcke collected from mine tailings near the town of Cobalt, Ontario was compared in its metal tolerance with a population collected at an uncontaminated site (Baymouth, Ontario). Seedlings of the Cobalt population were tolerant to elevated levels of arsenic, cobalt and nickel, both compared with the Baymouth population and with other literature reports for ...
... Malvastrum coromandelianum leaf extracts are used to treat infectious diseases and various inflammatory conditions in folk medicine. This study was designed to isolate its bioactive secondary metabolites and determine their potential bioactivity. The crude leaf extract obtained from 80% methanol was successively partitioned with n-hexane, dichloromethane, ethyl acetate, n-butanol and water.The 80% ...
... This paper is the first to report cadmium tolerance in a dicotyledonous species, Silene vulgaris (Moench.) Garcke. The response to cadmium of five populations originating from one uncontaminated and various heavy‐metal contaminated sites was examined under standardized conditions for three weeks. The tolerance index (TI), based on the mean relative growth rate (R), was determined. Populations orig ...
... Plant–microbe interactions are considered to be important processes determining the efficiency of phytoremediation of heavy metal-contaminated soils. However, relatively little is known about how these interactions are influenced by chromium (Cr) contamination. The effect of Cr stress on metal uptake, root organic acid composition, and rhizosphere bacterial communities was studied using two genoty ...
... This research aimed to indicate mechanisms involved in protection against the imbalanced generation of reactive oxygen species (ROS) during heavy metals (HMs) exposition of Silene vulgaris ecotypes with different levels of metal tolerance. Specimens of non-metallicolous (NM), calamine (CAL), and serpentine (SER) ecotypes were treated in vitro with Zn, Pb, and Cd ions applied simultaneously in conc ...
... The production of phytochelatins in roots of both cadmium–sensitive and cadmium–tolerant plants of Silene vulgaris (Moench) Garcke in response to Cd supply was recorded over a 7–day growth period. At the same level of Cd, sensitive plants produced more phytochelatins than tolerant ones. In sensitive roots this higher production of PCs was associated with a higher Cd content within one day. From th ...
... Wissadula hernandioides (L’Hér.) Garcke is native to Brazil and can be identified by its subshrub habit, cordate and discolor leaves with usually stellate trichomes, yellowish flowers arranged in paniculate inflorescences, and schizocarpic fruits. Before our finding, this species was recorded in Brazil only in Cerrado, Atlantic Forest, Amazon and Pantanal vegetation. The population found in Caatin ...

Abstract:
... Silene vulgaris occurs in Israel as a stolonifcrous tetraploid which forms mostly sexually polymorphic populations. Fully hermaphrodite and fully male‐sterile plants are linked by a range of intermediate forms which are gynomonoecious and bear hermaphrodite, male‐sterile, and partially male‐sterile flowers. Male‐sterile flowers differ from hermaphrodite ones by having a narrower calyx, a shorter c ...
... In this paper we aimed to assess the role of metallothionein-2b in Zn or Cd hypertolerance by analyzing the expression of SvMT2b in roots of metallicolous and non-metallicolous Silene vulgaris populations, as well as in interpopulation crosses segregating for tolerance to Zn or Cd. Plants were grown in hydroponic nutrient solution and Zn and Cd were supplied as sulphates after 1 week of preculture ...
... Malvastrum coromandelianum L. (Garcke) is extensively used in traditional medicinal systems to treat various ailments. In the present study, an alkali-soluble polysaccharide (MAP) was isolated from the leaves of M. coromandelianum in 1.15% (w/w) yield. MAP was composed of l-rhamnose, l-arabinose, d-xylose, d-glucose and d-galactose in a 1.00 : 6.04 : 19.88 : 1.07 : 3.03 molar ratio along with d-gl ...
... To explore the newer saponin resources, in vitro toxicity of saponin-enriched fraction (SEF) extracted from Silene vulgaris(SV) was evaluated for first time and compared with in vitro toxicity of SEF extracted from Sapindus mukorossi (SM) and Chlorophytum borivilianum (CV). All extracted SEF from diverse resources were characterized by immersing TLC plates in 0.5% RBC suspension method, by ethanol ...
