拟南芥（Arabidopsis thaliana） 是十字花科(Brassicaceae) 鼠耳芥属(Arabidopsis)的一种小小的开花植物。这种小小的有花植物，早在１６世纪就被Johannes Thal首先报导。它被用于植物突变与传统遗传分析研究超过了五十年。拟南芥是在植物科学，包括遗传学和植物发育研究中的模式生物之一，其在植物学中所扮演的角色正仿佛小白鼠在医学和果蝇在遗传学中的一样。
拟南芥是二倍体，有2n=10条染色体。拟南芥能作为植物中第一个被完全测序的物种，主要是由于（1）基因组小（约120Mb），结构简单，重复序列少（2）遗传周期短，仅需六周就能完成一次传代（3）大量的种子。它的测序是由国际合作共同完成，称为Arabidopsis Genome Initiative（AGI）。

The Arabidopsis Information Resource (TAIR, http://arabidopsis.org) 是拟南芥相关信息的数据库网站。Data in TAIR is derived in large part from manual curation of the Arabidopsis research literature and direct submissions from the research community. New developments at TAIR include the addition of the GBrowse genome viewer to the TAIR site, a redesigned home page, navigation structure and portal pages to make the site more intuitive and easier to use, the launch of several TAIR web services and a new genome annotation release (TAIR7) in April 2007. A combination of manual and computational methods were used to generate this release, which contains 27,029 protein-coding genes, 3889 pseudogenes or transposable elements and 1123 ncRNAs (32,041 genes in all, 37,019 gene models). A total of 681 new genes and 1002 new splice variants were added. Overall, 10,098 loci (one-third of all loci from the previous TAIR6 release) were updated for the TAIR7 release.
