| 摘 要： | 多基因家族经历着生与死的进化并因此有助于生物的创新性进化。APETALA2类基因属于AP2转录因子家族中euAP2分支。该类基因具有特征性基元,并存在于蕨类植物、裸子植物和被子植物中。系统发育分析表明这类基因经历了生与死的进化。原位杂交和RT-PCR结果表明水稻的5个APETALA2类基因在表达模式上既是冗余又是不同的。根据基因系统发育树和表达模式讨论了这些基因的功能。

| Abstract: | The multigene families undergo birth-and-death evolution and thus contribute to biological innovations. The APETALA2-like genes belong to the euAP2 group of the AP2 gene family. These genes are characterized by several distinct motifs and exist in ferns, gymnosperms, and angiosperms. The phylogenetic analysis indicated that these genes have undergone the birth-and-death evolution. The five APETALA2-like genes in rice (Oryza sativa L.) display redundant but distinct expression patterns as demonstrated by RT-PCR and in situ hybridization. The potential functions of these genes were discussed on the basis of phylogenetic and expression pattern. |
