其名称来源于古德语“Kogge”或荷兰语“Kog”,意为“船体”。随着汉萨同盟的崛起,Cog逐渐成为北欧海上贸易网络的核心工具,承担了货物运输、渔业捕捞甚至海盗活动等多种职能。 二、技术特征与功能优势 Cog船的主要技术革新体现在以下方面: 船体结构:采用平底、高舷侧和单桅方形帆设计,船尾设有...
eggNOG(evolutionary genealogy of genes:Non-supervised Orthologous Groups，http://eggnog.embl.de/)数据库:是国际上普遍认可的同源聚类基因群的专业注释数据库，包括来自原始COG/KOG的功能分类，以及基于分类学的功能注释。目前该数据库（v4.0）包含170万个直系同源类群，覆盖了3686个物种，给定了107个不同的分类...
Functional annotation of the detected orthologous clusters is one of the crucial and most labor-consuming aspects of the C/KOG analysis. Given the well-known inaccuracy of the currently available schemes for automatic annotation (e.g., Refs. 5,18, and references therein), no attempt was made ...

is probably due to the relatively small number of eukaryotic genomes included in this analysis and is expected to level off with the growth of the eukaryotic genome collection. This view is compatible with the observed dependence of the KOG coverage on the number of genes (Table1), which sugge...
