Abstract

This article aimed to detect the existence of barley-specific Nikita and Sukkula retrotransposons in domestic geese samples and to evaluate the evolutionary relationships between these and other transposons belonging to the family Anatidae. Inter-retrotransposon-amplified polymorphism-polymerase chain reaction (IRAP-PCR) method was performed for these retrotransposons movements in three diverse domestic goose populations (Chinese × Embden crossbred, Turkish White, and Turkish Multicolor). Polymorphism ratios were between 0 and 33% in all samples for Nikita and 0–73% in all samples for Sukkula. In addition, intrapopulation genetic polymorphism rates were also 0–15% in Chinese × Embden crossbred, 0–25% in Turkish White, 0–25% in Turkish Multicolor for Nikita; while 0–27% in Chinese × Embden, and 0–50% in Turkish Multicolor for Sukkula. There was no polymorphism for Sukkula among Turkish White samples. Moreover, the neighbour-joining method was used for phylogenetic tree construction using 38 sequences of different ducks, geese, and swans. In silico analyses supported the transitions of retrotransposons in the family Anatidae. It is concluded that transposon mobility among the phylogenetically distant species may lead to understanding evolutionary relationships. This report is one of the first studies investigating retrotransposon movements in domestic geese, revealing a new perspective on the goose genome regarding mobile genetic elements.

家鹅（Anser anser domesticus）基因组中尼基塔（Nikita）和苏库拉（Sukkula）反转座子的可转移性

摘要本文旨在检测家鹅样本中存在的大麦特异性Nikita和Sukkula反转座子，并评估这些反转座子与其他鹅科转座子之间的进化关系。在三个不同的家鹅种群（中国×安布登杂交鹅、土耳其白鹅和土耳其多色鹅）中，对这些逆转录转座子的运动进行了逆转录转座子间扩增多态性聚合酶链反应（IRAP-PCR）方法。尼基塔所有样本的多态性比率在 0 至 33% 之间，苏库拉所有样本的多态性比率在 0 至 73% 之间。此外，尼基塔的中国×安布登杂交种种内遗传多态性率为 0-15%，土耳其白种为 0-25%，土耳其多色种为 0-25%；而苏库拉的中国×安布登杂交种种内遗传多态性率为 0-27%，土耳其多色种为 0-50%。在土耳其白样本中，Sukkula 没有多态性。此外，利用不同鸭、鹅和天鹅的 38 个序列，采用邻接法构建了系统发生树。硅学分析支持逆转座子在鸭科中的过渡。研究认为，转座子在系统发育距离较远的物种之间的流动性可能有助于了解进化关系。该报告是首次对家养鹅的逆转录转座子移动进行调查的研究之一，揭示了鹅基因组移动遗传因子的新视角。

期刊介绍： The journal retains its traditional interest in evolutionary research that is of relevance to geneticists, even if this is not explicitly genetical in nature. The journal covers all areas of genetics and evolution,including molecular genetics and molecular evolution.It publishes papers and review articles on current topics, commentaries and essayson ideas and trends in genetics and evolutionary biology, historical developments, debates and book reviews. From 2010 onwards, the journal has published a special category of papers termed ‘Online Resources’. These are brief reports on the development and the routine use of molecular markers for assessing genetic variability within and among species. Also published are reports outlining pedagogical approaches in genetics teaching.
