A.拟南芥是芥菜科的小型开花植物。它有4-5周的世代时间，可以自花授粉或异花授粉，每株种子多达104粒。存在许多可见的和生物化学的突变，并且已经通过重组映射到构成单倍体核型的5条染色体中的1条。拟南芥具有非常小的单倍体基因组大小（. 7倍。107个核苷酸对）和低水平的胞嘧啶甲基化。与其他高等植物相比，它的核DNA中几乎没有重复DNA。
A. thaliana is a small flowering plant of the mustard family. It has a 4-5 wk generation time, can be self- or cross-pollinated and bears as many as 104 seeds per plant. Many visible and biochemical mutations exist and have been mapped by recombination to 1 of the 5 chromosomes that comprise the haploid karyotype. Arabidopsis has an extraordinarily small haploid genome size (.apprx. 7 .times. 107 nucleotide pairs) and a low level of cytosine methylation for an angiosperm. It appears to have little repetitive DNA in its nuclear DNA, in contrast to other higher plants.
