“…Слід зауважити, що у тритикале виявлено значне зростання вмісту флавоноїдів за дії УФ-В [24]. У рослин цього виду встановлено також збільшення вмісту окремих флавоноїдів у відповідь на атаку Sitobion avenae й Oulema melanopus [25]. Припускають, що ці сполуки можуть бути важливими для запобігання надмірному окиснювальному стресу за дії не лише абіотичних, а й біотичних чинників.…”

The mechanisms of low-temperature adaptation of triticale (w Triticosecale Wittm.), an intergeneric hybrid that combining high productivity and frost resistance, are not well understood. In particular, the question remains open about the contribution of secondary metabolites to the functioning of its antioxidant system during the formation of frost resistance. The dynamics of the total content of phenolic compounds, flavonoids, and separately the amount of anthocyanins under cold hardening conditions (6 days at temperature of 2—4 °C) of seedlings of varieties with different frost resistance: Buket and Raritet (winter, high-frost-resistant), and Alexandra (winter, notfrostresistant) and Pidzymok kharkivskiy (facultative, less resistant) were studied. The content of phenolic compounds in non-hardened seedlings of various genotypes differed slightly, only in the Pidzymok kharkivskiy variety was slightly lower compared with other studied genotypes. Hardening caused a slight increase in the total content of phenolic compounds in all studied varieties. The total amount of flavonoids in non-hardened seedlings of various genotypes differed slightly. Six-day hardening led to an increase in the content of flavonoids in the seedlings of all studied varieties by 1.7—1.9 times, with no significant differences between varieties. The content of anthocyanins in the non-hardened seedlings of various varieties was different: it was the highest for the Buket variety, and the lowest for the Pidzymok kharkivskiy variety. During the process of cold hardening, it was increasing and had reached approximately the same values in the varieties Buket, Raritet and Alexandra, however, in the least frost-resistant variety Pidzymok kharkivskiy this index was significantly lower. The conclusion about the contribution of anthocyanins, but not secondary metabolites in general, to the formation of frost resistance of triticale seedlings and the antioxidant defense system at low temperatures was made.

“…Polyphenols, synthesized in a wide variety of fruits, legumes, and herbs, interestingly serve to protect against biotic and abiotic stresses caused by insects and parasites [ 1 , 2 , 3 ]. However, much attention is presently given to dietary polyphenols in view of their evident health benefits.…”

Insight into Polyphenol and Gut Microbiota Crosstalk: Are Their Metabolites the Key to Understand Protective Effects against Metabolic Disorders?

Lifestyle factors, especially diet and nutrition, are currently regarded as essential avenues to decrease modern-day cardiometabolic disorders (CMD), including obesity, metabolic syndrome, type 2 diabetes, and atherosclerosis. Many groups around the world attribute these trends, at least partially, to bioactive plant polyphenols given their anti-oxidant and anti-inflammatory actions. In fact, polyphenols can prevent or reverse the progression of disease processes through many distinct mechanisms. In particular, the crosstalk between polyphenols and gut microbiota, recently unveiled thanks to DNA-based tools and next generation sequencing, unravelled the central regulatory role of dietary polyphenols and their intestinal micro-ecology metabolites on the host energy metabolism and related illnesses. The objectives of this review are to: (1) provide an understanding of classification, structure, and bioavailability of dietary polyphenols; (2) underline their metabolism by gut microbiota; (3) highlight their prebiotic effects on microflora; (4) discuss the multifaceted roles of their metabolites in CMD while shedding light on the mechanisms of action; and (5) underscore their ability to initiate host epigenetic regulation. In sum, the review clearly documents whether dietary polyphenols and micro-ecology favorably interact to promote multiple physiological functions on human organism.

“…Phenolic compounds play essential roles in interspecific competition and plant defense mechanisms against biotic and abiotic stresses [ 1 ] and radiation, and might act as regulatory molecules, pigments, or fragrances [ 2 ]. These compounds are an integral part of our daily lives, and they play important roles in the pharmaceutical, cosmetics, food, and agricultural industries.…”

Secondary phenolic metabolites are defined as valuable natural products synthesized by different organisms that are not essential for growth and development. These compounds play an essential role in plant defense mechanisms and an important role in the pharmaceutical, cosmetics, food, and agricultural industries. Despite the vast chemical diversity of natural compounds, their content in plants is very low, and, as a consequence, this eliminates the possibility of the production of these interesting secondary metabolites from plants. Therefore, microorganisms are widely used as cell factories by industrial biotechnology, in the production of different non-native compounds. Among microorganisms commonly used in biotechnological applications, yeast are a prominent host for the diverse secondary metabolite biosynthetic pathways. Saccharomyces cerevisiae is often regarded as a better host organism for the heterologous production of phenolic compounds, particularly if the expression of different plant genes is necessary.
