| Abstract: |
| There are a series of physiological and biochemical changes during fruit growth and ripening, among which
the transformation of starch into soluble sugar is one of the main changes in climacteric fruits. Starch serves as a stored
energy substance of fruit before its degradation is initiated. When the fruit reaches a certain stage of maturity, under the
action of some promoting factors, the starch is degraded and transformed into soluble sugar, which makes the soluble solids
of fresh fruit increase dramatically and provides necessary favor compounds for the fruit.The degradation of starch involves
the regulation of key enzyme transcription by a large number of transcription factors and modification of protein levels after
gene translation. In this paper, the research progress of starch degradation in four common high-starch fruits was reviewed,
the enzyme genes involved in starch degradation and its transcriptional regulators were introduced. This paper helps to
understand the characteristics of starch degradation during fruit ripening, and provides theoretical basis and research
direction for the future research of starch metabolism in fruits. |
