Abstract Details

2001, MS, University of Cincinnati, Arts and Sciences : Biological Sciences.
The American chestnut tree Castanea dentata (Marsh.) Borkh was one of the largest and most valued trees in the Eastern United States until the accidental introduction of the blight fungus Cryphonectria parasitica (Murrill). The blight virtually eradicated the American chestnut from its former range. It was imported on Asian chestnut trees, in the early part of the 20th century. We have used a combination of molecular and biochemical techniques in an attempt to identify the compound(s) in the Chinese chestnut, Castanea mollissima (Blume), that give it resistance to the chestnut blight. A broad survey of components of Chinese chestnut bark was evaluated for anti-fungal activity. This survey identified that the 938 molecular weight compound chestanin consistently encouraged fungal growth. A separated fraction containing at least two compounds with apparent molecular weight around 1300 Daltons was also found. Preliminary data shows the compounds in this fraction decrease the rate of mycelial growth and sporulation. As a result of experiments using different media, an improved recipe for callus production from immature green leaves or embryo tissues of American chestnut was identified.
