Identification of Phytophthora species on fruit crops in Turkey by polyacrylamide gel electrophoresis1

Abstract

To identify 11 Phytophthora isolates obtained from lemon, peach and apple trees, and from strawberry plants, in the Mediterranean region of Turkey, protein, acetylesterase, peroxidase and catalose band patterns of these isolates and the same bands of 10 identified isolates of Phytophthora citrophthora, P. cinnamami and P. cactarum were compared. These 11 regional isolates were identified on the basis of the similarity of their protein and enzyme band patterns to those of identified Phytophthora isolates. It was concluded that protein band patterns could be used for identification of Phytophthora species. With enzyme band patterns, however, it may be possible to identify at species level but it is more practical to use this method only for identification of subspecies.
