摘要
前人研究显示MYB(V-myb avian myeloblastosis viral oncogene homolog)转录因子对应答植物逆境胁迫等有重要作用,甘蔗MYB转录因子的研究报道并不太多。通过对与甘蔗亲缘关系近的禾本科作物玉米、高粱和水稻MYB转录因子基因家族的密码子使用偏好性进行比较分析。结果表明,3个物种的MYB转录因子的蛋白质序列上存在高度的保守性,仅有部分密码子使用不太一样,此外,分析还显示基因碱基组成有可能在一定程度上影响了密码子的偏好使用。
Previous studies showed that the plant MYB （V-myb avian myeloblastosis viral oncogene homolog） transcription factor played an important role in response to adversity stress, but very limited reports on sugarcane MYB transcription factors were found. During the investigation of synonymous codon usage in maize, sorghum and rice MYB family transcription factor genes, we found highly conserved in protein sequence and similarity in codon usage for MYB transcription factor among the three different but related plant species though some codon usage being different. In addition, the bias of codon usage was affected by base composition of the gene in some degree. The results presented in the present study not only provide the basis for the further functional prediction of MYB transcription factor gene family in sugarcane, but also for the interaction analysis between different members of the MYB family.
