项目摘要
Before starting this project, Platypus quercivorus was recorded from Japan, India, Indonesia, New Guinea, and Taiwan. We collected the species from Thailand and Vietnam, which is the new record of the distribution of this species. We found that two types were distributed in Japan, which were thought to be two independent species ("Japan-Sea type" and "Pacific -Ocean type" in this MS). These two types differed from each other morphologically and genetically. These morphological and genetic differences coincided. Regarding the "Japanese-Sea type" two populations were recognized by DNA analysis: mainland population and central Ryukyu population. Genetic distance between the two populations was farthest among four regional populations by DNA analysis including Thai and Indonesian populations. The mainland population was most close to Thai population, and the central Ryukyu population was to the Indonesian. It was difficult to explain this result by natural pattern. The mainland population was introduced from Thailand after the last glacier age probably by human activity. On contrary, the pathogenic fungus, Raffaelea quercivora did not varied so much as P quercivorus did: R. quercivora that was collected from P quercivorus in Taiwan and Japan were classified into one trade. We hypothesized an origin of the Japanese oak wilt disease as follows: Japan-Sea-type P quercivorus that were introduced from Thailand after glacier age were hijacked by R. quercivora carried by the Pacific-Ocean type at southern Kyushu, in which these two types coexist. Because Quercus crispula is highly susceptible to R. quercivora and because reproduction rate of P quercivorus is high in dead Q. crispula, epidemics of the Japanese oak wilt spread rapidly and the distribution range of the Thai population of the "Japan-Sea-type" P. quericovrus expanded fast
在开始该项目之前,柏拉图Quercivorus是从日本,印度尼西亚,新几内亚和台湾记录的。我们从泰国和越南收集了该物种,这是该物种分布的新记录。我们发现在日本分布了两种类型,这些类型被认为是两个独立物种(在此MS中是“日本 - sea类型”和“太平洋 - 西方类型”)。这两种类型在形态和遗传上彼此之间有所不同。这些形态学和遗传差异重合。关于“日本类型”的人群通过DNA分析认可了两个人群:大陆人口和中部鲁京人口。通过包括泰国人群和印尼人群在内的DNA分析,这两个人群之间的遗传距离在四个区域人群中最远。大陆人口最接近泰国人口,而中央鲁京人口则是印尼人。很难通过自然模式来解释这一结果。大陆人口是在最后一个冰川年龄之后从泰国引入的,这可能是通过人类活动而引入的。相反,病原性真菌,拉斐尔·奎尔维拉(Raffaelea Quercivora)的变化不如P Quercivorus所差异很大:从台湾和日本的P Quercivorus收集的R. Quercivora被归类为一种贸易。我们假设日本橡木枯萎病的起源如下:冰川年龄后从泰国引入的日本型P Quercivorus被Southern Kyushu的Pacific-ocean Type携带的R. Quercivora劫持了,这两种类型在这两种类型中。因为Quercus crispula非常容易受到R. Quercivora的影响,并且因为p Quercivorus的繁殖率很高。死亡Q。Crispula,日本橡木枯萎病的流行迅速传播,泰国人口的分布范围以及“ Japan-sea-Sea-Type” P. Quericovrus的泰国人口的分布范围很快扩张。
