Summary
This study describes the GTG-banded karyotype of the small-toothed mole (Euroscaptor parvidens) for the first time. Comparative analysis reveals distinct cytogenetic signatures and evolutionary pathways in mole divergence.
Area of Science:
- * Mammalian Cytogenetics
- * Molecular Evolution
- * Biodiversity Genomics
Background:
- * Increasing number of mole species confirmed by genetic methods.
- * Gaps in cytogenetic data for many mole species.
- * Need for detailed karyotype analysis for evolutionary insights.
Purpose of the Study:
- * Describe the GTG-banded karyotype of Euroscaptor parvidens.
- * Compare karyotypes within Euroscaptor and with Oreoscaptor.
- * Investigate chromosomal evolution and rearrangements in moles.
Main Methods:
- * GTG-banded karyotyping of Euroscaptor parvidens.
- * Comparative karyotype analysis of Euroscaptor and Oreoscaptor species.
- * Zoo-fluorescence in situ hybridization (Zoo-FISH) using Talpa altaica chromosomes.
Main Results:
- * First description of the GTG-banded karyotype for Euroscaptor parvidens.
- * Identification of species-specific cytogenetic signatures in studied moles.
- * Evidence of high rates of karyotypic reshuffling in Asian mole genera, particularly Euroscaptor.
Conclusions:
- * Proposed ancestral karyotype for the Urotrichini tribe.
- * Chromosomal rearrangements, including pericentric inversions, are key drivers of mole divergence.
- * The lineage of Euroscaptor parvidens shows the highest rate of chromosomal change.

10.1K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

02:31Synteny and Evolution
3.3K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

02:54Evolutionary Relationships through Genome Comparisons
5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

02:37Gene Duplication and Divergence
6.2K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

01:54Convergent Evolution
27.9K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

02:05Gene Evolution - Fast or Slow?
7.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...
