Abstract
Phytophthora parasitica Dastur (= Phytophthora nicotianae Breda de Haan), being able
to attack a wide variety of plants, is a very notorious plant pathogen in the central and
southern Taiwan. It has been shown that there are variations in the morphology,
pathogenicity, and virulence among P. parasitica isolated from different host species,
indicating that differentiation may have arisen in P. parasitica isolated from different host
species. The purpose of this study was to analyze the genotypes of P. parasitica by DNA
fingerprinting, using reverse transcriptase sequence of PARTN1 as a genetic marker.
PARTN1 is a copia-like retrotransposon identified in this fungus. A total of 46 P. parasitica
isolates were analyzed. The results indicate that, although the hybridization patterns
obtained for each isolate are highly polymorphic, PARTN1 can indeed distinguish P.
parasitica isolated from (1) tobacco, (2) dieffenbachia, or (3) loquat, which are known as
atypical P. parasitica. Thus, PARTN1 could be very useful in studies on the phylogenetics
and population biology of P. parasitica .
