Original title: Zuo Jinhua's team from the Vegetable Center of Beijing Academy of Agriculture and Forestry Sciences and British and American scientists reveal a new mechanism of ultraviolet light UV-C regulating the maturation and senescence of green pepper fruits after harvest
Recently, the Beijing Academy of Agriculture and vegetables Center (National Engineering Research Center for Vegetables) into the left-China Research Associate team and the British University of Nottingham DoProfessor nald Grierson (Royal Academy of Sciences, Chinese Academy of Engineering, Foreign Member) team, the American professor Li Li of Cornell University (USDA-ARS) team in the joint area of agriculture, forestry science Q1 TOP journal Postharvest Biology forbid Technology (IF5-year : 5.
821) Online published a report entitled UV-C irradiation Delays the Physiological Changes of Bell Pepper fruit during Storage of research papers, reveals ultraviolet UV-C irradiation of green peppers regulation mechanism of fruit ripening and senescence, becomes green peppers Postharvest quality deterioration The research on the regulation mechanism provides a new basis
Green pepper fruit is rich in nutrition, unique flavor, and has certain health benefits.
It is an indispensable vegetable for human health
As a typical non-respiratory mutation type fruit, the postharvest ripening and senescence of green pepper fruits is a complex and orderly physiological and biochemical process, including changes in color, flavor, texture, aroma and other metabolites.
These changes are caused by multiple genes.
The fine coordinated regulation is achieved
Ultraviolet light irradiation preservation technology is a common cold sterilization technology.
Ultraviolet light treatment is beneficial to maintain the physiological characteristics and nutritional quality of fruits and vegetables after harvest
In this study, the green pepper fruit was used as the material, and the whole transcriptomics and metabonomics method were used to deeply explore the regulation mechanism of common ultraviolet light UV-C radiation on the postharvest ripening and senescence of green pepper fruit.
The expression profiles of mRNAs and ncRNAs in the control group and the treatment group are different, and a ceRNAs network model that synergistically regulates the maturation and senescence of green pepper fruits after harvest was constructed
Studies have found that UV-C radiation treatment mainly affects the expression of related genes and metabolites in the biosynthetic pathway of flavonoids, phenylalanine, tyrosine, tryptophan and phenylpropanin in green pepper fruits
For the first time in the world, this study uses a combination of whole transcriptome and metabonomics to reveal the molecular mechanism of UV-C irradiation that regulates the postharvest ripening and senescence of green pepper fruits, and provides information for postharvest biological research on non-respiratory jump fleshy fruits.
