Carnivorous Plant Ejects Junk DNA

Posted by samzenpus on from the who-needs-it? dept.

sciencehabit writes "The carnivorous humped bladderwort, found on all continents except Antarctica, is a model of ruthless genetic efficiency. Only 3% of this aquatic plant's DNA is not part of a known gene, new research shows. In contrast, only 2% of human DNA is part of a gene. The bladderwort, named for its water-filled bladders that suck in unsuspecting prey, is a relative of the tomato. The finding overturns the notion that this repetitive, non-coding DNA, popularly called 'junk' DNA, is necessary for life."

    I often eject junk DNA myself, and it is highly efficient compared to courting a female.
