| genetic diversity of phytophthora infestans sensu lato in ecuador provides new insight into the origin of this important plant pathogen. | abstract the metapopulation structure of phytophthora infestans sensu lato is genetically diverse in the highlands of ecuador. previous reports documented the diversity associated with four putative clonal lineages of the pathogen collected from various hosts in the genus solanum. this paper simultaneously analyzes diversity of the complete collection of isolates, including a large number that had not yet been reported. this analysis confirmed the existence of three pathogen populations, which a ... | 2004 | 18943538 |
