Abstract

Transcription factors (TFs) are proteinaceous complex, which bind to the promoter regions in the DNA and affect transcription initiation. Plant TFs control gene expressions and genes control many physiological processes, which in turn trigger cascades of biochemical reactions in plant cells. The databases available for plant TFs are somewhat abundant but all convey different information and in different formats. Some of the publicly available plant TF databases may be narrow, while others are broad in scopes. For example, some of the best TF databases are ones that are very specific with just one plant species, but there are also other databases that contain a total of up to 20 different plant species. In this review plant TF databases ranging from a single species to many will be assessed and described. The comparative analyses of all the databases and their advantages and disadvantages are also discussed.

摘要

转录因子(TFs)是一种蛋白质复合物,可与 DNA 中的启动子区域结合,并影响转录起始。植物 TFs 控制基因表达,基因控制许多生理过程,而这些过程又会在植物细胞中引发一系列生化反应。现有的植物 TFs 数据库虽然数量较多,但提供的信息和格式却各不相同。一些公开的植物 TF 数据库可能范围较窄,而另一些则范围较广。例如,一些最好的 TF 数据库仅针对一个特定的植物物种,但也有其他数据库包含多达 20 个不同的植物物种。在本综述中,我们将评估和描述从单个物种到多个物种的植物 TF 数据库。我们还讨论了对所有数据库的比较分析及其优缺点。
