Background and objective: The genus <i>Viola</i>, a member of the Violaceae family, is renowned for its ornamental flower crops. Additionally, <i>Viola</i> species are relatively pest-resistant easy to manage. They widely used in gardens, some their flowers even edible. In this study, our focus was on <i>V. cornuta</i> cv. Penny Red Wing (hereinafter referred...
objective: oxidative stress plays a key role in the pathophysiology of brain ischemia and neurodegenerative disorders.previous studies indicated that viola tricolor and viola odorataare rich sources of antioxidants. this study aimed to determine whether these plants protect neurons against serum/glucose deprivation (sgd)-induced cell death in an in vitro model of ischemia and neurodegeneration....
*In plants, epigenetic variations based on DNA methylation are often heritable and could influence the course of evolution. Before this hypothesis can be assessed, fundamental questions about epigenetic variation remain to be addressed in a real-world context, including its magnitude, structuring within and among natural populations, and autonomy in relation to the genetic context. *Extent and ...
The Hawaiian endemic Viola kauaensis A. Gray has a broad distribution in bogs of Kaua`i and a limited distribution on mesic ridges in the Ko`olau Mountains of O`ahu. Based on differences in scale, the O`ahu populations of Viola kauaensis had previously been described as a distinct taxon. The taxonomic status of the O`ahu populations was reevaluated through a morphometric analysis of all varieti...
Viola L. is a botanical genus with approximately 525 to 620 species, spread worldwide. Several violets are traditionally used as edible flowers and have been recently proved be source of bioactive compounds, including flavonols, flavanols, benzoic acids, cinnamic acids. However, no information available about the phytochemical profile calcarata complex, which found in Alpine environment. Thus, ...
Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...
Patients with schizophrenia (SZ) often display social cognition disorders, including Theory of Mind (ToM) impairments and communication disruptions. Thought language disorders appear to be primarily a disruption of pragmatics, SZ can also experience difficulties at other linguistic levels including the prosodic one. Here, using an interactive paradigm, we showed that SZ individuals did not use ...
The aromatic roots of Viola arvensis and V. rafinesquii were studied in order to determine the chemical nature and anatomical localization of their volatile compounds. Gas chromatography and mass spectroscopy revealed a single detectable volatile compound, methyl salicylate. Light microscopy and differential staining with Sudan III indicates the source of this compound to be enlarged secretory ...
