Plant cis-acting regulatory DNA elements (PLACE) database: 1999.

PLACE (http://www.dna.affrc.go.jp/htdocs/PLACE/) is a database of nucleotide sequence motifs found in plant cis-acting regulatory DNA elements. Motifs were extracted from previously published reports on genes in vascular plants. In addition to the motifs originally reported, their variations in other genes or in other plant species in later reports are also compiled. Documents for each motif in the PLACE database contains, in addition to a motif sequence, a brief definition and description of each motif, and relevant literature with PubMed ID numbers and GenBank accession numbers where available. Users can search their query sequences for cis-elements using the Signal Scan program at our web site. The results will be reported in one of the three forms. Clicking the PLACE accession numbers in the result report will open the pertinent motif document. Clicking the PubMed or GenBank accession number in the document will allow users to access to these databases, and to read the of the literature or the annotation in the DNA database. This report summarizes the present status of this database and available tools.PLACE (http://www.dna.affrc.go.jp/htdocs/PLACE/) 是一个收录植物顺式作用调控DNA元件（cis-acting regulatory DNA elements）中核苷酸序列基序（nucleotide sequence motifs）的数据库。该数据库的基序均提取自已发表的维管植物基因相关研究报告。除原始报道的基序外，后续研究中其他基因或其他植物物种内出现的该基序变异体也被一并收录。PLACE数据库中每个基序的详情文档，除包含基序序列外，还附有该基序的简要定义与说明，以及可获取的相关文献的PubMed编号和GenBank登录号。用户可通过本网站的Signal Scan程序，将查询序列与顺式作用元件进行比对检索。检索结果将以三种格式之一呈现。点击检索结果中的PLACE数据库登录号，即可打开对应基序的详情文档。点击文档中的PubMed或GenBank登录号，用户即可跳转至对应数据库，查阅相关文献或DNA数据库中的注释信息。本报告概述了该数据库及现有可用工具的当前发展状况。
