By now, so many species' genomes have been sequenced that another one is far from being news. But I couldn't resist this one.

I've added to the article's list:
- Influenza virus: 13,500 base pairs
- Escherichia coli bacterium: 5 million bp's
- Brewer's yeast: 12 M bp's
- Fruit fly: 140 M bp's
- Walnut tree: 650 M bp's
- Human: 3 billion bp's
- Giant sequoia: 8 B bp's
- Coast redwood: 27 B bp's
- Axolotl salamander: 28.4 B bp's
“You think of plants generally — they don't have brains, so they can’t be that complicated, but a redwood has to stay in the same place for thousands of years and fight off everything that comes its way,” said Steven Salzberg, a professor of biomedical engineering at Johns Hopkins University in Baltimore, who skippered the sequencing work. “It has to have a pretty robust ability to fight off fungi, microbes, insects, beetles, and a vast array of temperatures and humidities.”
The plan now is to analyze the genes in multiple trees, identify their genetic traits and determine why some thrive and others don’t. Ultimately, the researchers hope to develop genetic variation models for the various groves of old growth.
“Now we can screen for genetic diversity and make restoration decisions,” said Emily Burns, the director of science for Save the Redwoods League. “We want to know which genes are influential for drought tolerance and fire resistance. It’s the road map for how we are going to conserve the species in the future.”

One tree in Redwood National and State Parks, near Crescent City (Del Norte County), is 2,520 years old. The largest of the Sierra sequoia giants, which generally live longer than their coastal cousins, is 3,240 years old, according to a Save the Redwoods League study.
