Association Mapping and Development of Marker-Assisted Selection Tools for the Resistance to White Pine Blister Rust in the Alberta Limber Pine Populations.

Front Plant Sci 2020 15;11:557672. Epub 2020 Sep 15.

USDA Forest Service, Dorena Genetic Resource Center, Cottage Grove, OR, United States.

Since its introduction to North America in the early 1900s, white pine blister rust (WPBR) caused by the fungal pathogen has resulted in substantial economic losses and ecological damage to native North American five-needle pine species. The high susceptibility and mortality of these species, including limber pine (), creates an urgent need for the development and deployment of resistant germplasm to support recovery of impacted populations. Extensive screening for genetic resistance to WPBR has been underway for decades in some species but has only started recently in limber pine using seed families collected from wild parental trees in the USA and Canada.

in Korea: New Records and a New Species.

Mycobiology 2019 18;47(4):368-377. Epub 2019 Sep 18.

School of Biological Sciences and Institute of Microbiology, Seoul National University, Seoul, Korea.

The genus (Agaricales, Basidiomycota) is easy to recognize at the genus level because of big, fleshy basidiocarps with squamules covering the pileus; a single or double annulus; and big, thick-walled basidiospores with a germ pore. However, morphological identification is often unreliable in due to similar morphological features among species. Due to the uncertainty of previous morphological identification in the genus it is necessary to re-examine Korean using molecular data. Read More

Epidemiology of Exobasidium Leaf and Fruit Spot of Rabbiteye Blueberry: Pathogen Overwintering, Primary Infection, and Disease Progression on Leaves and Fruit.

Plant Dis 2019 Jun 17;103(6):1293-1301. Epub 2019 Apr 17.

Department of Plant Pathology, University of Georgia, Athens, GA.

Epidemiological field studies utilizing disease monitoring, spore trapping, and trap plants were conducted on rabbiteye blueberry () between 2014 and 2017 to shed light on the epidemiology of Exobasidium leaf and fruit spot, an emerging disease in the southeastern United States caused by the fungus . Wash plating of field-collected blueberry tissue from the late dormant season through bud expansion showed that the pathogen overwintered epiphytically on blueberry plants in the field, most likely in its yeast-like conidial stage. Agrichemical applications during the dormant season altered epiphytic populations of the pathogen, which correlated directly with leaf spot incidence later in the spring. Read More
