摘要: 为揭示毛竹重要变型的全基因组突变类型,选取4个有代表性的毛竹变型,采用高通量重测序技术,进行全基因组重测序,测序深度12×。分别提取毛竹4个变型与参考基因组间发生非同义突变的SNP、CDS区发生InDel与SV的基因,比较可以发现,2个秆形变异的竹种圣音竹和厚壁毛竹基因组的变异基因数目和变异类型相近,而2个秆色变异的竹种黄槽毛竹和黄皮花毛竹基因组的变异数目和变异类型相近。4个毛竹变型均存在多个基因同时存在多种类型突变。将变异基因与GO、COG、KEGG等功能数据库进行比对、注释,共获得1 739个参与细胞壁、细胞膜合成的基因,501个细胞骨架构建相关基因,1 785个转录因子相关基因,1 324个信号转导相关基因,104个赤霉素相关基因,76个激素代谢相关基因,1 938个叶绿素合成相关的基因,73个类胡萝卜素合成代谢相关基因和68个花青素合成调控基因,这些差异基因分别在毛竹秆形和秆色调控方面起着重要作用。

Abstract: For an overall understanding of the whole genome of 4 representative variations,re-sequencing was used for high-throughput sequencing with 12 depth to detect its variations. By comparing the genes with non-synonymous SNP,InDel and SV in CDS,the variation numbers and types of two variations on culm shape, Phyllostachys edulis f. tubaeformis and Phyllostachys edulis f. pachyloen were similar,and the other two variations on culm color, Phyllostachys edulis f. luteosulcata and Phyllostachys edulis f. huamozhu were similar. And multiple genes occurred multiple types of mutations simultaneously. By comparing and annotating the mutant genes with GO,COG,KEGG and other functional databases,a total of 1 739 genes involved in cell wall and cell membrane synthesis,501 cytoskeletal construction-related genes,1 785 transcription factors,1 324 signal transduction genes,104 gibberellins and 76 hormone genes,1 938 chlorophyll synthesis related genes,73 carotenoids synthetic metabolism related genes and 68 anthocyanin synthesis regulation genes were obtained. These genes play an important role in the regulation of bamboo culm shape and color.
