Partial characterization of the X chromosome of Diuraphis noxia (Hemiptera: Aphididae)

We present the first sequencing results after separation of the X chromosome of Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), the largest known X chromosome described to date, using flow cytometry. The X chromosome of D. noxia is 0.1824 pg (1C) and an estimated 178.4 Mb (1C) in size. Mapping confirmed that the X chromosome contains 13,799 protein coding genes, but with a slight bias towards GC richness when compared to the complete D. noxia genome. Here we present the first sequencing results after separation of the X chromosome of Diuraphis noxia (Kurdjumov, Hemiptera: Aphididae), the largest known X chromosomes described to date, using flow cytometry. The X chromosome of D. noxia is 0.18 pg (1C) and an estimated 178 Mb (1C) in size. Mapping confirmed that the X chromosome contains 13,799 protein coding genes, but with a slight bias towards GC richness when compared to the complete D. noxia genome.
