Scientists Sequence Genome of Coast Redwood genetics biology science
Coast redwood forests were extensively logged following immigration of Europeans into California.
Restoration and conservation efforts rely critically on the ability to measure and monitor genetic variation. Such markers have not existed for coast redwood and can only be developed following transcriptome or whole-genome sequencing. Nearly nine times larger than the human genome, the redwood genome has 26.5 billion base pairs of DNA, and it is hexaploid, meaning redwoods have six sets of chromosomes. Humans have 3 billion base pairs of DNA and are diploid, with two sets of chromosomes.When comparing the coast redwood genome sequence to that of other conifers, the researchers found hundreds of gene families unique to the coast redwood.
