To study and analyze the new mechanism of fruit ripening regulation

Reporters recently learned from the Institute of Botany of the Chinese Academy of Sciences, the institute researcher Qin Guozheng team and researcher Tian Shiping team initially clarified the DNA methylation and RNA methylation there is an inseid relationship, revealed the new mechanism of fruit ripening regulation, for the clarification of the mature regulatory network provides a new way of thinking. The results were published recently in Genomic Biology.
RNA methylation is the most abundant modification method on mRNA, widely found in animals, plants, fruit flies, yeast and other urns. RNA methylation modification plays multiple roles in mRNA metabolism, affecting development and other important biological processes.
By comparing changes in the different stages of maturation of tomato fruits, as well as differences in the fruits of wild and mature defect mutants, the researchers found that RNA methylation modification showed a dynamic trend during fruit maturation, and that the overall level of RNA methylation decreased gradually as the fruit matured, similar to DNA methylation; Given the multiple functions of DNA methylation and RNA methylation, the feedback regulation mechanism presented in this study is also applicable to other biological processes.
believe that fruit maturation is a very complex process, influenced by internal and external factors. The analysis of mature regulation mechanism can not only recognize the important stage of plant development in theory, but also provide a basis for improving fruit quality and prolonging storage and preservation time.
