Analysis of Phenolic Compounds of and Growing in the Russian Far East.

The Russian Far East is a region of unique biodiversity, with numerous plant species, including and . These plants are considered a serious threat to biodiversity and are classified as threatened species. However, plants synthesize and accumulate a variety of metabolites that are valued for their positive effects on human health.

Regulation of Anthocyanin Accumulation in Tomato L. by Exogenous Synthetic dsRNA Targeting Different Regions of Gene.

RNA interference (RNAi) is a regulatory and protective mechanism that plays a crucial role in the growth, development, and control of plant responses to pathogens and abiotic stresses. In spray-induced gene silencing (SIGS), exogenous double-stranded RNAs (dsRNA) are used to efficiently regulate target genes via plant surface treatment. In this study, we aimed to evaluate the effect of specific exogenous dsRNAs on silencing different regions (promoter, protein-coding and intron) of the target tomato gene, encoding an R3-type MYB repressor of anthocyanin biosynthesis.

Numerical indicators of absorption spectra of green leaf extract obtained from plants of different life forms.

The study was carried out using 58 species of terrestrial plants of different life forms at the start of their fruiting stage. Photoreceptive systems of the leaves were assessed by means of unconventional numerical indicators of absorption spectra, relative photoabsorption coefficient, photosynthetic pigments' integral absorption intensity and relative absorption intensity coefficient. As the study showed, the leaves of all trees and light-demanding grasses favoring open spaces, which were subjected to the study were featured by the lowest values of numerical indicators of absorption spectra (NIAS).
