摘要: SOC1（SUPPRESSOR OF OVEREXPRESSION OF CO1）/AGL20（AGAMOUS-LIKE 20）是MADS-box家族一员，在植物开花过程中起着重要的调控作用，它能够整合来自光周期途径、春化途径、自主开花途径和赤霉素途径中的信号，并与其他基因相互作用共同调节植物的开花时间以及花的类型和花分生组织。目前已经证明SOC1基因的过表达可以促进植物提前开花，而soc1突变体则会表现出晚花的表型。相关研究也显示，SOC1在植物开花之外的其他生命活动中也起着重要作用。本研究主要对SOC1及其同源基因在植物开花和其他生理活动中的功能以及SOC1基因的表达调节等研究进展进行综述，通过对30种植物的SOC1同源基因序列进行聚类分析，发现SOC1基因的同源性基本反映了物种间的亲缘关系，最后对该基因的研究前景提出展望，为以后SOC1及其同源基因的相关研究提供一定的参考。图3表1参42Abstract: SOC1（SUPPRESSOR OF OVEREXPRESSION OF CO1） / AGL20（AGAMOUS-LIKE 20），one member of the MADS-box family，plays an important role in regulating plant flowering by integrating signals involved in photoperiod, vernalization，and gibberellin and autonomous pathways as well as interacting with many other genes to regulate the flowering time，floral patterning，and floral meristem determinancy. Recent studies have proved that the overexpression of SOC1 resulted in early flowering，and soc1 mutant plants showed later flowering than the wild type Arabidopsis thaliana. Besides affecting flowering activity，SOC1 also functions in other physiological activities of plants. In this paper，SOC1 and homologous genes in flowering plants and other physiological activities，and functions of SOC1 gene expression regulation research progress were reviewed. The phylogenetic dendrogram of SOC1 homologue analysis found that SOC1 gene homology reflected the genetic relationship among species. This offered prospects of future relevant gene research of SOC1 with the homologous genes providing reference. ［Ch，3 fig. 1 tab. 42 ref.］
