摘要
利用8个全长mRNA基因序列比较了竹类植物和水稻等禾本科作物的系统进化和序列组成等。结果表明,在与水稻、玉米和麦类作物的比较中,竹类植物与水稻有着最近的亲缘关系和更相似的基因序列特征(GC含量分布和密码子使用频率),它们甚至比水稻与玉米或水稻与麦类之间的亲缘关系更近。这一结果提示,水稻作为禾本科植物的模式物种,应与竹类植物存在良好的基因组共线性关系,水稻基因组序列信息对竹类植物基因组研究与分析具有重要参考价值。
Phylogenetics and Sequence composition of bamboos and cereals were analyzed based on current 8 full-length mRNA sequences in the public nucleotides databases. The results indicated that bamboos had more shorter phylogenetic distance and similar sequence composition( GC content and codon usage)with rice than other cereals. The results suggested that rice, as model plant for Poaceae, should have significant genomic synteny with bamboos, and its genomic sequences are important resource for bamboo genome research.
