Copper tolerance in a population of Silene vulgaris ssp. maritima (A. & D. Love) at Dolfrwynog Bog near Dolgellau, North Wales

Abstract

Clones of Silene vulgaris ssp. maritima individuals from Dolfrwynog Bog, North Wales and from a coastal control site were propagated under standardised environmental conditions. After five months, cuttings were taken and tested for copper tolerance by means of root extension analysis in solutions of various different copper concentrations. Indices of tolerance suggested that individuals from the Dolfrwynog population were more resistant to elevated copper concentrations than were the control population individuals. Due to the initial five months under standardised conditions, it was assumed that the cloned plant material would have lost all plastic adaptive responses to its native environment. If this assumption was valid then the differences in copper tolerance observed between the two populations had a genetic basis and the Dolfrwynog Bog population is a copper tolerant ecotype.

A neutralizing human antibody binds to the N-terminal domain of the Spike protein of SARS-CoV-2

“…We performed a competition-binding assay using ELISA for several representative mAbs to determine whether there are overlapping antigenic sites between different mAbs, with CR3022 being used as a positive control mAb that reported to bind the SARS-CoV-2 RBD (Fig. 2C) (37). Among these mAbs, 4A8 in group 2A competed with 1M-1D2 in group 2B.…”

Effect of genotype, Cr(III) and Cr(VI) on plant growth and micronutrient status in Silene vulgaris (Moench)

“…Data from these studies show S. vulgaris to be an interesting species in the early stages of revegetation and soil restoration. Regarding genotypes, Cu has been the only metal studied to evaluate differences to metal uptake among genotypes of S. vulgaris (Price & Abrahams, 1994). There is no information about physiological traits and heavy metal tolerance between genders of S. vulgaris and about the ability of this species to tolerate and accumulate Cr.…”
