DNA fingerprinting uncovers a new sexually reproducing population of Phytophthora infestans in the Netherlands. Until the early nineteen eighties the Phytophthora infestans population in Europe was dominated by a single clonal lineage. The introduction of new, sexual compatible isolates lead to a reemergence of potato late blight. The sexual spores (oospores) can survive in harsh conditions and give rise to genetically diverse progeny with higher adaptability.
