在开花植物中,成熟胚囊由7个细胞组成,即珠孔端的2个助细胞和1个卵细胞,合点端的1个中央细胞和3个反足细胞。除反足细胞外,这些胚囊成分细胞作为细胞命运决定和细胞类型指定的模型,在受精和种子形成中的作用已被广泛研究。目前,人们对反足细胞的功能及其细胞类型特异性基因表达模式知之甚少。其中一个原因是与观察和分离细胞以进行详细的功能分析有关的困难。在这里,我们报告了一种反足细胞分离和转录组分析的方法。我们鉴定了反足细胞特异性标记系K44-1,并在此基础上建立了一套高质量、高数量分离反足细胞的方法。反足细胞基因的PCR验证表明,分离的细胞是合格的,可以用于转录组分析和细胞类型特异标记基因的筛选。分离的细胞在培养条件下可存活一周。该方法可用于高效、高质量地分离拟南芥反足细胞,将促进拟南芥反足细胞的功能研究。这增加了我们对反足细胞规范的分子调控机制的理解。
In flowering plants, the mature embryo sac consists of seven cells, namely two synergid cells and an egg cell at the micropylar end, one central cell, and three antipodal cells at the chalazal end. Excluding the antipodal cell, as a model for the study of cell fate determination and cell type specification, the roles of these embryo sac component cells in fertilization and seed formation have been widely investigated. At this time, little is known regarding the function of antipodal cells and their cell type-specific gene expression patterns. One reason for this is difficulties related to the observation and isolation of cells for detailed functional analyses. Here, we report a method for antipodal cell isolation and transcriptome analysis. We identified antipodal cell-specific marker line K44-1, and based on this marker line, established a procedure allowing us to isolate antipodal cells with both high quality and quantity. PCR validation of antipodal-specific genes from antipodal cell cDNA showed that the isolated cells are qualified and can be used for transcriptome analysis and screening of cell type-specific marker genes. The isolated cells could keep viable for a week in culture condition. This method can be used to efficiently isolate antipodal cells of high quality and will promote the functional investigation of antipodal cells in Arabidopsis thaliana. This increases our understanding of the molecular regulatory mechanism of antipodal cell specification.
