57921465 story Pine Tree Has Largest Genome Ever Sequenced 71 Posted by samzenpus on Thursday March 20, 2014 @11:26PM from the it's-how-you-use-it dept. sciencehabit (1205606) writes "Using a single pollinated pine seed, researchers have sequenced the entire genome of the loblolly pine tree--and it's a doozy. The tree's genome is largest yet sequenced: 22.18 billion base pairs, more than seven times longer than the human genome. The team found that 82% of the genome was made up of duplicated segments, compared with just 25% in humans. The researchers also identified genes responsible for important traits such as disease resistance, wood formation, and stress response."
