Abstract

To identify nucleolus organizing regions (NORs), fluorescence in situ hybridization (FISH) with 18S rDNA probe was performed on chromosomes of Tenthredocampestris Linnaeus, 1758 (Tenthredinidae), Argeciliaris (Linnaeus, 1767) (Argidae) (n = 10 in both) and Aulacideahieracii (Bouché, 1834) (Cynipidae) (2n = 20). In all these species, a single pericentromeric rDNA cluster per haploid karyotype was detected. This number of NORs is confirmed as ancestral for the order Hymenoptera.

膜翅目 Tenthredinoidea 和 Cynipoidea 超科 rDNA 簇的数量和位置：更新。

为了确定核仁组织区（NORs），使用 18S rDNA 探针对 Tenthredocampestris Linnaeus, 1758（Tenthredinidae）、Argeciliaris (Linnaeus, 1767) (Argidae) (n = 10 in both) 和 Aulacideahieracii (Bouché, 1834) (Cynipidae) (2n = 20) 的染色体进行了荧光原位杂交（FISH）。在所有这些物种中，每个单倍体核型都检测到一个单中心染色体 rDNA 簇。这一 NORs 数量被确认为膜翅目的祖先。
