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.
为了提供更多关于 2007 年至 2011 年中国青岛海域绿潮（浒苔）爆发的起源信息，本研究基于 ITS、rbcL 和 5S 序列调查了江苏省紫菜筏架上绿藻的多样性。2010 年和 2011 年，从不同地点和航次采集了 84 份绿藻样本。根据 ITS 和 rbcL 序列，来自紫菜筏架的样本分为四个分支：Linza-procera-prolifera（LPP）复合体、U. flexuosa、Blidingia sp. 和 Urospora spp.。然而，基于分辨率更高的 5S rDNA 标记物，84 个样本中只有一个属于 U. prolifera。结合之前的报道，青岛海域浒苔爆发可能有多个来源，紫菜养殖筏架可能是其中之一。
