Functional genomic resources for potato

Considerable functional genomic resources have been developed by the potato research community in the past decade, including expressed sequence tag (EST) libraries, SAGE libraries, microarrays, molecular-function maps, and mutant populations. This article reviews the types, characteristics, strengths, limitations, and appropriate applications of these resources for genomic research and discusses perspectives on future directions. This wide selection of resources available to potato researchers complements efforts to sequence the entire genome and advances made in the development of saturated genetic maps.
