云兰属植物

In the mutant plant,a genecalled Lcyc is extensively methylated and thus not expressed--and thismethylated state is heritable by subsequent generations of toadflax plants.

在突变体植物中，一个叫Lcyc基因广泛甲基化，因此不能表达。这一甲基化状态在云兰属植物中是能遗传的。

In the 9September 1999issue of Nature,molecular geneticist Enrico Coen and colleagues at the John Innes Centre inNorwich,U.K.,reported that a mutant version of the toadflax plant--which results in flowers with radial rather thanbilateral symmetry--is due to an epimutation.

在1999年9月9日的《自然》杂志上，英国Norwich，John Innes 中心的分子遗传学家Coen和同事报道了云兰属植物Linaria vulgaris的一个突变体特征。这一特异突变导致它的花从双面对称变为辐射状。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
