Cluster Analysis on the Nucleotide Sequences of Six Genes in Rice

摘要

[Objective]This study aimed to construct four-dimensional graphics of nucleotide sequences of six genes in rice( GluB-6,GluB-7,PDIL2,OsMPK1,OsCATC,OsCATA) and to conduct phase-space clustering,thus demonstrating the relationship between the structure and function of rice genes. [Method]Base sequences were represented by four-dimensional graphics and clustered in the phase space. The relationship between clustering results and biological characteristics of these genes were analyzed. [Result] Genes with similar four-dimensional graphics exhibit similar biological characteristics. [Conclusion] Four-dimensional graphics of genes with different functions and base lengths present phase-space relationship with their biological functions,which provided an effective way for the prediction of gene function.
