DescriptionPhellinus noxius (Corner) G. H. Cunn is a vastly destructive, fast-growing pathogen that affects a wide range of woody hosts in pan-tropical areas, including Asia, Australia, Africa, and Oceania (Ann et al. 2002). This invasive pathogen causes brown root-rot disease on cacao, coffee, and rubber, as well as diverse fruit, nut, ornamental, and other native/exotic trees, and little host specificity is known to occur (Sahashi et al. 2010). Symptoms of P. noxius infection can include reduced tree growth, defoliation, and branch dieback; however, P. noxius can also survive as a saprophyte by colonizing the heart wood and other organic matter. Brown root-rot disease can develop over several years, or in some cases, P. noxius infection can cause tree mortality within a year. Understanding the genetic diversity and evolutional history of P. noxius populations worldwide well help assess the evolutionary origins, worldwide movement, and potential ecological differences within P. noxius, which will contribute to the development of management strategies. Our objective was to understand the genetic diversity and evolutional history of P. noxius populations worldwide to assess the evolutionary origins, worldwide movement, and potential ecological differences within populations of P. noxius.
