Chicken (Gallus gallus), as the most economically important poultry, is a classical and ideal model for studying the mechanism of vertebrate developmental biology and embryology. However, the sex determination and differentiation in chicken is still elusive, which limited the application and slowed down many basic studies in chicken.
We applied PacBio Iso-seq to multiple spatiotemporal embryo-gonad tissues in the male and female chicken, which contain the blastoderm (E0, un-differentiation stage), genital ridge (E3.5-6.5, sex-differentiation stage) and gonads (E18.5, full-sex-differentiation stage). We obtained 51,479 and 48,356 full-length transcripts in male and female chicken embryo, respectively. The comprehensive annotated and evaluated these transcripts. The 1,293 and 1,556 candidate lncRNAs, 5,766 and 4,211 AS events in male and female. Collectively, our data constitutes a grand increase in the known number of lncRNA, AS (Alternative splicing) and Poly(A) during chicken embryo sex-differentiation and plays an important role in improving current genome annotation. In the meantime, the data will be enriched the functional studies in other birds.
鸡(Gallus gallus)作为最具经济重要性的家禽,是研究脊椎动物发育生物学和胚胎学机制的经典和理想模型。然而,鸡的性别决定和分化仍然难以捉摸,这限制了其应用并减缓了许多基础研究。
我们应用 PacBio Iso-seq 对雄性和雌性鸡的多个时空胚胎性腺组织进行了研究,这些组织包含囊胚(E0,未分化阶段)、生殖嵴(E3.5-6.5,性别分化阶段)和性腺(E18.5,完全性别分化阶段)。我们分别在雄性和雌性鸡胚胎中获得了 51479 个和 48356 个全长转录本。全面注释和评估了这些转录本。在雄性和雌性中分别有 1293 个和 1556 个候选 lncRNA、5766 个和 4211 个 AS 事件。总的来说,我们的数据大大增加了已知的鸡胚胎性别分化过程中 lncRNA、AS(选择性剪接)和 Poly(A)的数量,并有助于改进当前的基因组注释。同时,这些数据将丰富其他鸟类的功能研究。
