By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Acyclic Hydrocarbons - Alkenes is now available. According to news originating from Beijing, People’s Republic of China, by NewsRx correspondents, research stated, “Through natural or human selection, many fleshy fruits have evolved vivid external or internal coloration, which often develops during ripening. Such developmental changes in color are associated with the biosynthesis of pigments as well as with degreening through chlorophyll degradation.”

Funders for this research include National Natural Science Foundation of China, Beijing Municipal Commission of Education, The 111 Project.

Our news journalists obtained a quote from the research from China Agricultural University, “Here, we demonstrated that natural variation in the coding region of the gene ETHYLENE RESPONSE FACTOR17 (ERF17) contributes to apple (Malus domestica) fruit peel degreening. Specifically, ERF17 mutant alleles with different serine (Ser) repeat insertions in the coding region exhibited enhanced transcriptional regulation activity in a dual-luciferase reporter assay when more Ser repeats were present. Notably, surface plasmon resonance analysis showed that the number of Ser repeats affected the binding activity of ERF17 to the promoter sequences of chlorophyll degradation-related genes. In addition, overexpression of ERF17 in evergreen apples altered the accumulation of chlorophyll. Furthermore, we demonstrated that ERF17 has been under selection since the origin of apple tree cultivation.”

According to the news editors, the research concluded: “Taken together, these results reveal allelic variation underlying an important fruit quality trait and a molecular genetic mechanism associated with apple domestication.”
