| genetic specificity in the white pine-blister rust pathosystem. | abstract four of eight white pine species native to western north america surveyed for resistance to white pine blister rust by artificial inoculation showed classical hypersensitive reactions (hr) at frequencies ranging from very low to moderate. mendelian segregation, indicating a single dominant allele for resistance (cr3), was observed in southwestern white pine (pinus strobiformis), as it was previously in sugar pine (p. lambertiana, cr1) and western white pine (p. monticola, cr2). hr was p ... | 2002 | 18943999 |
| phellinus coronadensis: a new species from southern arizona, usa. | phellinus coronadensis is characterized and described morphologically as a new species from southern arizona, usa. this fungus was previously reported as p. torulosus based on morphological similarities of the basidiomes and type of wood decay. however, p. coronadensis is restricted to two mountain ranges in southern arizona and found almost exclusively on living southwestern white pine (pinus strobiformis). phellinus torulosus is found primarily in europe and parts of asia and is primarily asso ... | 2003 | 21156590 |
