2008年7月初，世界各地的新闻机构报道了一场巨大的藻类水华，威胁到即将在中国青岛举行的奥运会帆船比赛。然而，该受谴责的肇事者的身份仍未得到讨论。通过形态学和分子生物学数据，包括质体编码大亚基核酮糖1，5-二磷酸羧化酶基因（rbcL）和核编码rDNA内转录间隔区（ITS）的序列数据，我们已经确定了引起水华的病原菌。形成水华的藻类福尔斯在绿色海藻石莼（Ulva prolifera O.F.）的形态学范围内。Muller（'Enteromorpha prolifera（O.F. Muller）J. Agardh '），但我们的系统发育分析表明，它形成了一个分支的代表石莼linza-procera-prolifera（LPP）复合体。中国的rbcL序列与日本、新西兰、芬兰和葡萄牙的rbcL序列一致，表明该分类群分布广泛。rDNA ITS序列与日本分离物的种复合体有较近的亲缘关系。青岛水华是绿色浪潮的典型例证，这种浪潮在全球沿着越来越多地出现。
In early July 2008, news agencies worldwide reported on a vast algal bloom that was threatening the upcoming Olympic sailing events in Qingdao, China. The identity of the culpable alga, however, remained undiscussed. We have identified the alga that caused the bloom by means of morphological and molecular data, including sequence data of the plastid encoded large subunit ribulose 1,5-bisphosphate carboxylase gene (rbcL) and the nuclear encoded rDNA internal transcribed spacer (ITS) region. The bloom-forming alga falls within the morphological limits of the green seaweed Ulva prolifera O.F. Muller ('Enteromorpha prolifera (O.F. Muller) J. Agardh') but our phylogenetic analyses show that it forms a clade with representatives of the Ulva linza-procera-prolifera (LPP) complex. The Chinese rbcL sequences are identical to those of specimens collected from Japan, New Zealand, Finland and Portugal, suggesting that the taxon is widely distributed. rDNA ITS sequences showed a close affinity with Japanese isolates of the species complex. The Qingdao bloom is a typical illustration of a green tide, which occurs increasingly along several coasts worldwide.
