Current Status of Deltabaculoviruses, Cypoviruses and Chloriridoviruses Pathogenic for Mosquitoes

There are a variety of viral pathogens that cause disease in mosquitoes with most belonging to three major groups. The most common viruses of mosquitoes are the baculoviruses (DBVs) (Baculoviridae: Deltabaculovirus), cytoplasmic polyhedrosis viruses (CPVs) (Reoviridae: Cypovirus) and the iridoviruses (MIVs) (Iridoviridae: Chloriridovirus). Baculoviruses and iridoviruses are DNA viruses while cypoviruses are the main RNA viruses in mosquitoes. This review presents an overview of the current status and recent advancements in understanding the biology and molecular features of mosquito pathogenic viruses.     

DNA多面体数学模型的研究进展

近年来,越来越多的DNA多面体在实验室中被合成出来,深入理解这些新颖的多面体结构和性质成了新的挑战,迫切需要综合运用数学、生物、化学等理论和手段进行研究。现在综述文献的基础上,以两种十四面体为例,系统介绍通过DNA多面体的新欧拉公式和两种示性数来刻画DNA多面体的拓扑结构,探索DNA多面体的组装规律和性质。
