About this Research Topic
Fruits are of considerable commercial importance, and their contents of primary metabolites such as sugars, organic acids, and amino acids/amides are important determinants of the quality of many fruits, whereas in others such as olive fat content and composition is the major determinant. Further, in fleshy fruits, nuts and the fruits of seed crops, such as cereals and legumes, the fruit tissues also play an important role in the storage and transformation of imported assimilates before their delivery to the developing seeds. In the tissues of many fruits, the vacuole occupies a large proportion of cell volume, and thus compartmentation of metabolites within the vacuole must be considered. The contents of different abundant primary metabolites change greatly during fruit development, and for a given metabolite these changes can show either similarities or differences between fruits of different species.
In recent years considerable progress has been made in understanding various aspects of fruit primary metabolism. Therefore, it is timely to produce a collection of papers reviewing our current understanding of primary metabolism in fruits. This Research Topic article collection will include two types of article:
1. The first type will review certain aspects of fruit metabolism, including sugar metabolism, color and aroma changes, import of assimilates, postharvest biochemistry and molecular biology, fruit softening, etc.
2. The second type will deal with the metabolism of a given fruit (e.g. avocado, grape, tomato, etc.) or group of related fruits (e.g. citrus fruits, pome fruits, stone fruits, etc). These latter type of articles could vary depending on the type of information that is available for that fruit or group of fruits. Nevertheless, a balanced account of the metabolism of the given fruit or group of fruits is required. Aspects that are necessary to address this requirement are: changes in metabolism during development (including changes in abundant metabolites), compartmentation of metabolism, metabolism of sugars, organic acids and amino acids. Depending on the considered fruit, other features could be considered such as fat metabolism and certain aspects of secondary metabolism.
The authors of the articles will be selected among the experts in the given area. Spontaneous submissions will be considered only if preceded by an abstract describing the focus of their planned project.
