在GenBank和EMBL核酸数据库中发现了一个新的反向重复元件家族成员Stowaway，它与40多个单子叶和双子叶植物基因密切相关。Stowaway元件的特征在于保守的末端反向重复、小尺寸、靶位点特异性（TA）和形成稳定的DNA二级结构的潜力。一些元件位于测序的cDNA的3'末端，并向其宿主基因提供多聚腺苷酸化信号。其他元件位于几个基因的5'上游区域，似乎含有先前鉴定的顺式作用调节结构域。虽然Stowaway元件与最近发现的Tourist元件共享许多结构特征，但这两个家族没有显着的序列相似性。Stowaway和Tourist家族一起定义了一类重要的新的短反向重复元件，它们可能存在于所有开花植物基因组中。
Members of a new inverted repeat element family, named Stowaway, have been found in close association with more than 40 monocotyledonous and dicotyledonous plant genes listed in the GenBank and EMBL nucleic acid data bases. Stowaway elements are characterized by a conserved terminal inverted repeat, small size, target site specificity (TA), and potential to form stable DNA secondary structures. Some elements are located at the extreme 3' ends of sequenced cDNAs and supply polyadenylation signals to their host genes. Other elements are in the 5' upstream regions of several genes and appear to contain previously identified cis-acting regulatory domains. Although the Stowaway elements share many structural features with the recently discovered Tourist elements, the two families share no significant sequence similarity Together, the Stowaway and Tourist families serve to define an important new class of short inverted repeat elements found in possibly all flowering plant genomes.
