Specific host recognition mechanisms of marine virus, a dinoflagellate-infecting virus

赤潮异形病毒 (HaV) 是一种大型病毒，专门感染有害的水华形成鞭毛虫。基于现场调查和宿主克隆与HaV克隆之间的交叉反应性测试，表明这种菌株依赖性感染可能在确定赤潮嗜血杆菌天然种群的克隆组成和维持种内多样性方面发挥重要作用。在这项研究中，为了阐明特异性宿主感染的机制，过量产生了特异性宿主识别蛋白Vp183蛋白。

Heterosigma akashiwo virus (HaV) is a large virus specifically infecting the harmful bloom-forming flagellate Heterosigma akashiwo. Based on field surveys and cross-reactivity tests between the host clones and HaV clones, suggesting that this strain-dependent infection may play an important role in determining the clonal composition and maintaining the intraspecies diversity of natural H. akashiwo populations. In this study, to elucidate the mechanism of the specific host infection, the Vp183 protein, the specific host recognition protein, was overproduced.
