| fungi isolated from flue-cured tobacco sold in southeast united states, 1968-1970. | flue-cured tobacco leaves, from low- and middle-stalk positions, offered for sale in each of two markets, within each of five tobacco types, were evaluated for moisture content (mc) and filamentous fungi during august through october in 1968, 1969, and 1970. alternaria alternata, penicillium cyclopium, aspergillus niger, aspergillus repens, and aspergillus flavus were most frequently isolated from cultured tissue. other filamentous fungi that grew from the tissue included species from four gener ... | 1972 | 4627970 |
| signatures of recombination in clonal lineages of the citrus brown spot pathogen, alternaria alternata sensu lato. | most alternaria spp. are considered asexual but recent molecular evolution analyses of alternaria mating-type genes show that the mating locus is under strong purifying selection, indicating a possible role in sexual reproduction. the objective of this study was to determine the mode of reproduction of an alternaria alternata sensu lato population causing citrus brown spot in central florida. mating type of each isolate was determined, and isolates were sequenced at six putatively unlinked loci. ... | 2013 | 23441968 |
