By conscious design, plant genomics initiatives have devoted initial resources to new technology development. Part of that money went to developing functional genomics approaches, and part to new sequencing technologies.
Sequencing Stakes: Celera Genomics Carves Its Niche

J. Craig Venter is no stranger to contradiction and controversy. He seems to thrive on it. In 1991, when the National Institutes of Health was haggling over patenting expressed sequence tags (ESTs)--a shortcut to identifying protein-encoding genes--Venter the inventor accepted a private offer to found The Institute for Genomic Research (TIGR) in Rockville, Md. TIGR would discover ESTs and give most of them to a commercial sibling, Human Genome Sciences (HGS), to market. ESTs are now a standard

For many years, geneticists determined the genetic makeup of organisms by examining the physical characteristics of their offspring. But with the discovery of the structure of the DNA double helix, first published by James D. Watson and Francis H.C. Crick in 1953 (Nature, 171:964-7), the science of genetics was forever changed. Scientists soon developed techniques to study the genetic message found in all living cells at the molecular level. One of most important of these methods was the use of

A Thousand Points of Light

Not so long ago, researchers had somewhat limited choices for locating and following a particular piece of DNA. A probe could be labeled using radioactivity, by kinasing an end or nick-translating the whole piece. A fragment of interest could be visualized (along with all other DNA and RNA species in the preparation) using ethidium bromide. With sufficient skill and patience an investigator could obtain from these rather crude techniques fairly impressive information, such as the precise 5' end
