Abstract

LINE-1 sequences have been linked to genome evolution, plasticity and speciation; however, despite their importance, their chromosomal distribution is poorly known in primates. In this perspective, we used fluorescence in situ hybridization (FISH) to map LINE-1 probes onto two representative platyrrhine species, Aotus nancymaae (Cebidae) and Alouatta belzebul (Atelidae), both characterized with highly rearranged karyotypes, in order to investigate their chromosomal distribution and role and to better characterize the two genomes. We found centromeric enrichment of LINE-1 sequences on all biarmed and acrocentric chromosomes co-localized with heterochromatin C-positive bands. This distribution led us to hypothesize that LINE 1 sequences may have a role in the centromere architecture and karyotype organization of platyrrhine genomes.

LINE-1序列与基因组进化、可塑性和物种形成有关;然而,尽管它们很重要,但它们在灵长类动物中的染色体分布却鲜为人知。在这方面,我们利用荧光原位杂交(FISH)技术将LINE-1探针定位到两种具有高度重排核型的platyrrhine物种Aotus nancymaae (Cebidae)和Alouatta belzebul (Atelidae),以研究它们的染色体分布和作用,并更好地表征这两种基因组。我们发现LINE-1序列在所有双臂和单中心染色体上的着丝粒富集与异染色质c阳性带共定位。这种分布使我们假设LINE 1序列可能在platyrrhine基因组的着丝粒结构和核型组织中起作用。

期刊介绍: Caryologia is devoted to the publication of original papers, and occasionally of reviews, about plant, animal and human karyological, cytological, cytogenetic, embryological and ultrastructural studies. Articles about the structure, the organization and the biological events relating to DNA and chromatin organization in eukaryotic cells are considered. Caryologia has a strong tradition in plant and animal cytosystematics and in cytotoxicology. Bioinformatics articles may be considered, but only if they have an emphasis on the relationship between the nucleus and cytoplasm and/or the structural organization of the eukaryotic cell.
