Abstract

Abstract:

Sugar is an important factor that determines fruit quality of citrus. Illustrating the characteristic and regulation mechanism of citrus fruit sugar metabolism and transport will greatly contribute to regulating sugar accumulation accurately. In this paper，the mechanisms underlying sugar accumulation were comprehensively reviewed，we also summarized the differences of fruit sugar accumulation in various citrus varieties，the characteristics of sugar accumulation with fruit development and the relationship between sugar and the related enzyme activities. Subsequently，a model of metabolic differences between sucrose accumulation type and hexose accumulation type was mapped in citrus. Moreover，the storage process of sucrose from leaf（source organ）to fruit（sink organ）was described systematically，including phloem loading，unloading，transport and sucrose storage in fruit vacuole. Finally，a model of sugar transport from source to sink was constructed in citrus.

Key words: citrus, sugar, sucrose transport, sucrose metabolism, vacuolar storage
