The GeneChip Citrus Genome Array has been developed by scientists to improve the flavour of citrus fruits. The chip, manufactured by Affymetrix will help determine which genes are turned on in a tissue of citrus genes that are associated with taste, acidic content and disease, a process that could provide useful information to researchers in resolving existing problems and making improvements to the fruit.

The GeneChip Citrus Genome Array is made up of a glass wafer on which almost one million different pieces of citrus DNA are deposited on a grid or microarray using methods similar to those used to manufacture computer chips. The glass wafer is encased in a plastic container somewhat smaller than the size of a credit card.

The chip is the first commercial citrus microarray and allows analysis of expression of more than 20,000 different genes. The array will also be used to develop a detailed genetic map of citrus that will help researchers locate many genes.

Information generated will be used to develop new citrus varieties more efficiently and to develop new diagnostic tools for the improvement of the entire citrus agricultural industry.
