Abstract:

Sugar is not only the energy source but also an important kind of regulator of gene expression in plant. During the process of plant sucrose metabolism, especially during the process of fruits development, invertases catalyze sucrose hydrolyzation to produce hexoses that related to the quality of vegetable and fruits. Invertases are classified into acid invertases and neutral/basic invertases, with different functions. Meanwhile, different invertases have diverse expression patterns, which are influenced by different factors, such as organs and developmental specificity, sugars, stress and phytohormones. Despite the bulk of available knowledge on invertase at present there are still many questions remain to be elucidated further.

Key words: sucrose metabolism, invertase, gene expression, regulation of gene expression
