Application of prunus avium L. PaMADSs gene to adjustment and control of fruit coloring or fruit ripening softening

Abstract

The invention discloses an application of a prunus avium L. PaMADSs gene to adjustment and control of fruit coloring or fruit ripening softening. The effect of 4 E type MADS-box proteins positioned ona cell nucleus to prunus avium L. fruit ripening and softening is systematically analyzed, the inventor finds that the PaMADS7 gene adjusts and controls the prunus avium L. fruit softening by adjusting and controlling maturity of prunus avium L. fruits and directly activating expression of a polygalacturonase gene in an ABA signal way, so as to determine a new application of the PaMADS7 gene to adjustment and control of the maturity and softening of the prunus avium L. fruits. The inventor further finds that a PaMADS2 gene, a PaMADS4 gene or a PaMADS7 gene has the effect of adjusting and controlling coloring of prunus avium L. peel. The invention further provides a method for adjusting and controlling the maturity and softening of the prunus avium L. fruits or the coloring of the fruits.

Description

technical field [0001] The invention relates to a new application of the sweet cherry PaMADSs gene, in particular to a new application of the sweet cherry PaMADSs gene in regulating fruit coloring or fruit ripening and softening, and belongs to the field of new applications of the PaMADSs gene. Background technique [0002] European sweet cherry (Prunus avium L.) is an important economic fruit tree, which is widely planted in warm temperate regions all over the world. The fruit is bright in color, delicious in flavor and rich in nutrition. It contains carbohydrates, protein, vitamins, iron, calcium and potassium. Nutrients and minerals necessary for the human body, etc., are deeply loved by consumers (Kelley DS, Adkins Y, Laugero KD. 2018. A review of the health benefits of cherries. Nutrients 10,368). However, the sweet cherry fruit is easy to soften and deteriorate during the ripening process, resulting in a decline in fruit quality, intolerance to storage and a short shel...

Problems solved by technology

However, there is a shortage of molecular mechanisms regulating the ripening and softening of sweet cherry fruit, and only a few genes have been found to be related to the ripening and softening of sweet cherry fruit (AlkioM, Jonas
