Researchers decode first tree genome
Last year, the complete network of DNA in humans was decoded. Just last month, that same genetic sequence - also known as a genome - was revealed for the first time in a species of tree. The Black Cottonwood tree, commonly known as the poplar, was selected as a model species for the project partly due to its relatively small genome size, forestry Associate Professor Kyung-Hwan Han said. Understanding the genome information for the poplar tree will help tree biologists learn more about its growth cycles, Han said. He said he participated in the project as part of the International Populus Genome Consortium, a group of international scientists and researchers that work to map out genetic codes. The majority of the work in sequencing the DNA was done by the U.S.
