中文摘要：

Cerambycidae (长角牛甲壳虫) 是有食木的喂的习惯的翘目的一个大家庭。纤维素消化在这些喂木头的昆虫起一个重要作用。在这研究， transcriptomic 技术被用来获得一个 glycoside hydrolase 家庭 45 (GH45 ) 从 Mesosa myops 的绗维素酶和七 GH5 绗维素酶，典型长角牛甲壳虫。表达式动力学和进化关系的分析提供了对可加水分解纤维素的系统的完全的描述。与单个开发有关的表示动力学显示内长的 GH45 和 GH5 绗维素酶在 M 统治纤维素消化。myops。进化分析建议那 GH45 绗维素酶基因是在翘目亚目 Polyphaga 的一般基因。进化分析也显示在 Lamiinae 长角牛甲壳虫的 GH5 绗维素酶组仔细与木头喂被联系。这研究证明在 M 有一个复杂内长的可加水分解纤维素的系统。被属于二个 glycoside hydrolase 家庭的绗维素酶统治的 myops。

英文摘要：

The Cerambycidae （longhorn beetle） is a large family of Coleoptera with xylophagous feeding habits. Cellulose digestion plays an important role in these wood-feeding insects. In this study, transcrip- tomic technology was used to obtain one glycoside hydrolase family 45 （GH45） cellulase and seven GH5 cellulases from Mesosa myops, a typical longhorn beetle. Analyses of expression dynam- ics and evolutionary relationships provided a complete description of the cellulolytic system. The expression dynamics related to individual development indicated that endogenous GH45 and GH5 cellulases dominate cellulose digestion in M. myops. Evolutionary analyses suggested that GH45 cellulase gene is a general gene in the CoLeoptera Suborder Polyphaga, Evolutionary analyses also indicated that the GH5 cellulase group in Lamiinae longhorn beetles is closely associated with wood feeding. This study demonstrated that there is a complex endogenous cellulolytic system in M. myops that is dominated by cellulases belonging to two glycoside hydrolase families.
