| genetic variation in eastern north american and putatively introduced populations of ceratocystis fimbriata f. platani. | the plant pathogenic fungus ceratocystis fimbriata f. platani attacks platanus species (london plane, oriental plane and american sycamore) and has killed tens of thousands of plantation trees and street trees in the eastern united states, southern europe and modesto, california. nuclear and mitochondrial dna fingerprints and alleles of eight polymorphic microsatellite markers of isolates of c. fimbriata from these regions delineated major differences in gene diversities. the 33 isolates from th ... | 2004 | 15367115 |
| correlations between root-associated microorganisms and peach replant disease symptoms in a california soil. | replant disease often occurs when certain crops are "replanted" in a soil that had previously supported the same or similar plant species. this disease typically leads to reductions in plant growth, crop yields, and production duration, and its etiology remains ill-defined. the objective of this study was to identify microorganisms associated with peach replant disease symptoms at a field location in california, usa. soil samples were subjected to treatments to create various levels of replant d ... | 2012 | 23071565 |
