| 中文摘要: |
| 果实有机酸（特别是柠檬酸和苹果酸）含量是决定甜度或糖酸比等风味品质的一个重要指标，因此，调节酸度以提高果实品质一直是园艺领域的主要目标之一。但是，果实内有机酸代谢与调控是一个极为复杂的过程，牵涉到合成、转运、贮存和降解，而这些生物学过程均受到果实类型、基因型、果实发育、环境条件和栽培管理的综合影响。经过多年的遗传研究，一些与果实酸度连锁或相关的基因已经被克隆或鉴定，同时，分子生物学手段的应用增加了我们在基因表达水平上对酸度调控的理解，加上最近系统生物学的引入使得我们可以从系统水平上探测柑桔和苹果果实酸度的基因调控网络，所有这些进展为最终应用分子遗传学手段改进果实糖酸品质提供了基础。 |
| 英文摘要: |
| The content of organic acids (in particular citrate and malate) in fruits is a major determinant for the trait of sweetness or sugar/acid ratio, and thus manipulating the fruit acidity has become one of the major goals in horticultural fields. However, the organic acid metabolism and its regulation in fruits is an extremely complex process, involving synthesis, transport, storage and degradation. These biological processes are impacted by fruit types, genotypes, fruit development, environmental factors and management practices. Decades of genetic research have led to the cloning of genes linked to acidity or identification of genes associated with fruit acidity. Molecular biology studies have provided important insights into the regulation of gene expression important for the control of fruit acidity. Furthermore, recent introduction of systems biology approaches to transcriptome analysis resulted in the construction of fruit acidity-related gene coexpression networks in apple and citrus and thus has provided the systems view of fruit acidity control. Clearly, these exciting advances will provide an important basis for the future improvement of fruit quality via molecular genetic approaches. |
