针叶树基因组研究进展

The Research Progress of the Conifer Genomes

摘要:

摘要：针叶树作为全球重要的用材及生态树种，因其基因组巨大，一直以来基因组相关研究进展较慢。近年来随着新技术新方法的出现及投入的增加，从ESTs数据库的构建及基因家族分析、非编码小RNAs、转录表达谱、遗传图谱构建、基因组关联分析及QTL定位等研究方向对几种重要模式针叶树开展了广泛而深入的研究，取得了一批重要成果，极大地推动了针叶树种基因组研究进展。本文总结了近年来的针叶树基因组研究概况，并探讨了以后的研究方向，可为该领域的研究提供参考和借鉴。

Abstract:

Abstracts:Conifers are the major source of wood, biomass and many other products all over the word. Conifer genomes are extremely large，therefore related research is fraught with difficulties. In recent years, along with the new technology and new method appears and national investment increase, several important conifers have carried out extensive and in depth research on sequences and sequence based resources, datamining ESTs for gene family analyses, non coding small RNAs, transcript profiling, SNP resources and comparative mapping, association studies and QTL analyses and so on. The results of these studies have greatly promoted the conifer genomes research progress. This paper summarizes the progress on conifer genomes in recent years, and the future research directions are discussed also,in order to provide reference for the study in this field.
