Chickens are vital economic poultry and serve as exemplary models for avian research. The incomplete reference genome of chickens and the limited availability of full-length cDNA impede the identification of alternatively spliced transcripts, thereby delaying many fundamental chicken studies. We utilized PacBio Iso-seq technology on various chicken tissues, obtaining 170,162 full-length transcripts through comprehensive transcriptome sequencing and annotation. Of the identified transcripts, 38,925 lncRNAs were predicted and categorized into five models. Our data significantly increases the known number of chickens' lncRNAs and alternatively spliced transcripts are crucial in enhancing current genome annotations. Furthermore, this data will be invaluable for functional studies of other avian species.
鸡是重要的经济家禽,也是禽类研究的典范模型。鸡的参考基因组不完整以及全长cDNA的可用性有限,阻碍了可变剪接转录本的鉴定,从而延误了许多基础鸡研究。我们在各种鸡组织上利用PacBio Iso-seq技术,通过全面的转录组测序和注释获得了170,162个全长转录本。在鉴定出的转录本中,预测了38,925个长链非编码RNA,并将其分为五种模型。我们的数据显著增加了已知的鸡长链非编码RNA数量,并且可变剪接转录本对于增强当前的基因组注释至关重要。此外,这些数据对于其他禽类物种的功能研究将是非常宝贵的。
