A number of fir species ( Abies ) are produced as Christmas trees around the world. In particular, Fraser fir ( Abies fraseri (Pursh) Poir.) is popular as it yields high-quality Christmas trees in temperate North America and Europe. A Phytophthora sp. causing root rot on Fraser fir was isolated from a Christmas tree farm in Connecticut, U.S.A., and found to be new to science according to morphological and molecular phylogenetic analysis using multilocus DNA sequences from ITS, Cox1 , β- Tub , Nadh1 , and Hsp90 loci. Thus, it was described and illustrated as Phytophthora abietivora . An informative Koch's postulates test revealed that P. abietivora was the pathogen causing root rot of Fraser fir. |
