一种新型大DNA病毒（PlitV-1）感染海洋丝状褐藻Pilayella littoralis。它是在阿拉斯加收集的，感染其他不同地理来源的P. littoralis分离株。该病毒有一个二十面体的衣壳c。直径为161 nm，包含一个电子致密的核心。基因组由双链DNA组成，大小约为280 000个碱基对。该病毒潜伏在宿主的体细胞中，仅在诱导宿主的生殖器官时繁殖。它会导致孢子囊变形，导致不育，并且在结构上与其他褐藻病毒相似。PCR扩增编码硅叶外果皮病毒EsV-1部分结构糖蛋白的基因组序列，产生了与EsV-1获得的片段大小相似的片段。
A new large DNA virus (PlitV-1) infects the marine filamentous brown alga Pilayella littoralis. It was collected in Alaska and infects other P. littoralis isolates of different geographic origin. The virus has an icosahedral capsid of c. 161 nm in diameter, enclosing an electron-dense core. The genome consists of double-stranded DNA and is approximately 280 000 base pairs in size. The virus is latent in somatic cells of the host and is propagated only upon induction of the host's reproductive organs. It causes deformed sporangia, resulting in infertility, and is structurally similar to other brown algal viruses. PCR amplification of a genomic sequence coding for part of a structural glycoprotein of the Ectocarpus siliculosus virus EsV-1 produced a fragment of similar size to that obtained with EsV-1.
