Testing Blight Resistance in American Chestnuts

The American chestnut (Castanea dentata) was a keystone tree species in the eastern U.S., once found in the forest overstory from Maine to Georgia. The loss of the “mighty giant” to chestnut blight (Cryphonectria parasitica), a fungal disease accidentally imported from Asia in the early 1900s, reduced the once dominant chestnuts to remnant understory sprouts.…  More 

In the Genome of Loblolly Pine Lies Hope for Better Resistance to a Damaging Disease

U.S. Forest Service Southern Research Station (SRS) scientists co-authored the article published today in the journal Genome Biology that reports the sequencing, assembly, and annotation of the loblolly pine (Pinus taeda) genome. As the primary source of pulpwood and saw timber for the U.S. forest industry, loblolly pine is of great economic importance to the…  More
