马扎科夫斯基，塔博斯克五世，Zouhar M.，RYŠÁNEK P.，豪斯瓦特·E.，DOLEDIONAL P.（2006）：致病疫霉交配型A1和A2的发生和分布（蒙特）在捷克共和国的德巴里。植物保护。科学，42：41-48。2003年、2004年和2005年，从捷克共和国不同地区的马铃薯和番茄受感染作物的叶片、块茎和果实中共获得199株致病疫霉菌株。使用传统的配对试验和PCR标记分析交配型，107株A1和92 A2交配型。本研究首次报道了A2交配型致病疫霉在捷克共和国的存在和分布。这两种交配类型的共存可能使病原体能够有性繁殖，从而增加了全国范围内的种群多样性。
MAZÁKOVÁ J., TÁBORSKÝ V., ZOUHAR M., RYŠÁNEK P., HAUSVATER E., DOLEŽAL P. (2006): Occurrence and distribution of mating types A1 and A2 of Phytophthora infestans (Mont.) de Bary in the Czech Republic. Plant Protect. Sci., 42: 41–48. A total of 199 Phytophthora infestans isolates were obtained from leaves, tubers and fruits of infected crops of potato and tomato in different regions of the Czech Republic in 2003, 2004 and 2005. They were analysed for mating type using the conventional pairing assay and PCR markers; 107 isolates were of A1 and 92 of A2 mating type. No self-fertile isolate was found. Our study is the first report of the presence and distribution of the A2 mating type of P. infestans in the Czech Republic. The co-existence of the two mating types may enable the pathogen to reproduce sexually, thus enhancing the diversity of its population countrywide.
