为了解2007 - 2011年青岛海域增殖石莼水华的起源，利用ITS、rbcL和5S序列分析了江苏沿海条斑紫菜筏上生长的绿色藻类的多样性。2010年和2011年从不同地点和航次采集了84个绿色藻类样品。根据ITS序列和rbcL序列分析，条斑紫菜筏样品可分为4个分支，即链格石莼复合体（Ulva linza-procera-prolifera，LPP）、曲格石莼（Ulva flexuosa）、Blidingia sp.和尾孢石莼（Urospora spp.）。然而，基于一个更清晰的DNA标记5S rDNA，84个样品中只有一个属于U。增殖。结合以前的报道，很可能是美国。青岛海域紫菜水华可能有多个来源，紫菜养殖筏可能是原因之一。
To provide more information on the origin of the Ulva prolifera bloom in Qingdao sea area in China from 2007 to 2011, the diversity of green algae growing on the rafts of Porphyra yezoensis on the coast in Jiangsu Province was investigated based on ITS, rbcL and 5S sequences. Eighty-four of green algal samples from various sites and cruises in 2010 and 2011 were collected. According to ITS and rbcL sequences, samples from the rafts of P. yezoensis fell into four clades: Ulva linza-procera-prolifera (LPP) complex, Ulva flexuosa, Blidingia sp. and Urospora spp. However, based on the 5S rDNA, a more resolved DNA marker, only one of the 84 samples belonged to U. prolifera. Combined with the previous reports, it is likely that U. prolifera bloom in Qingdao sea area might consist of more than one origin, and Porphyra cultivation rafts might be one of the causes.
