核因子Y（NF-Y）是高度保守的三聚体激活剂，其以高特异性和亲和力识别广泛分布的CCAAT盒启动子元件。我们先前克隆了拟南芥的23个NF-Y基因的基因（Gene 264（2001）173）。现在，拟南芥基因组测序计划已经完成，我们提出的克隆，比对和表达谱的其余六个基因编码的三个NF-Y亚基。与我们之前的报告一致。这三个亚基的大多数新成员显示出独特的组织特异性模式，而另一个AtNF-YC 9是相当普遍的。(C)2002 Elsevier Science B.V.保留所有权利。
Nuclear factor Y (NF-Y) is a highly conserved trimeric activator that recognizes with high specificity and affinity the widespread CCAAT box promoter element. We previously cloned the genes of 23 NF-Y genes of Arabidopsis thaliana (Gene 264 (2001) 173). Now that the Arabidopsis genome sequencing project is complete, we present the cloning, alignments and expression profiles of the remaining six genes coding for the three NF-Y subunits. Consistent with our previous reports. most of the new members of the three subunits show a unique tissue-specific pattern, while another AtNF-YC9 is rather ubiquitous. (C) 2002 Elsevier Science B.V.
