New research reveals major difference in genomes of American and Chinese chestnut
The chromosomes of American and Chinese chestnut are not so similar after all, at least in one key region of the genome—the nucleolus organizing region (NOR).
The U.S. Forest Service was formed in 1905 and is currently an agency of the U.S. Department of Agriculture. The Forest Service manages 155 National Parks and wetlands in the United States. The U.S. Forest Service has overlapping control with other agencies involving habitat protection, water and maintenance of National Monuments. The primary role is to preserve and protect national forests and the ecosystem necessary to support it. The Forest Service publishes informative guides, trains and employs forest rangers and maintains public lands.
