法布尔，B.，卢斯，R.，皮尤，D.，和马卡。b . 2012。法国松树针叶枯病的出现是由隐种松树引起的吗？植物病理学102:47-54。针枯病（DNB）近年来在法国出现。此病是由两种亲缘关系较近的病原菌Dothistroma septosporum和d.p inii引起的。虽然这两个物种目前都存在于法国，但过去只报道了D. septosporum。我们调查了最近抵达法国的D. pail是否可能是DNB出现的原因。我们利用聚合酶链反应技术分析了具有DNB症状的松针标本，以研究法国松皮病的过去发生频率。我们还确定了septosporum和pini在国内的目前分布情况，并将其与法国森林卫生监测机构数据库中报告的DNB的空间格局进行了比较。虽然在1907年和1965年的植物标本馆标本中发现了D. pint，但过去在法国并不常见。今天，它是频繁的。虽然没有出现在全国各地，但北部和东部都没有。法国pini的分布与DSF数据库中报道的DNB的空间格局没有关系。因此，DNB在法国的出现不能用最近到来的D. pini来解释。
Fabre, B., loos, R., Piou, D., and Marcais. B. 2012. Is the emergence of Dothistroma needle blight of pine in France caused by the cryptic species Dothistroma pini? Phytopathology 102:47-54.Dothistroma needle blight (DNB) emerged in France in the past IS years. This disease is induced by two closely related species: Dothistroma septosporum and D. pini. Although both species are currently present in France, only D. septosporum was reported in the past. We investigated whether a recent arrival of D. pail in France could be a cause of the DNB emergence. We analyzed herbarium specimens of pine needles with DNB symptoms using polymerase chain reaction techniques to study the past frequency of D. pini in France. We also determined the present distribution within the country of D. septosporum and D. pini and compared it with the spatial pattern of DNB reported in the Departement de la Sante des Forets (DSF; French forest health monitoring agency) database. Although D. pint was detected on herbarium specimens from 1907 and 1965, it was not frequent in France in the past. Today, it is frequent. although not present throughout the country, being absent from the north and the east. There is no relationship between the D. pini distribution in France and the spatial pattern of DNB reported in the DSF database. Thus, the emergence of DNB in France cannot be explained by a recent arrival of D. pini.
