High heart rate associated early repolarization causes J‐waves in both zebra finch and mouse

Physiological Reports, 2021
High heart rates are a feature of small endothermic—or warm‐blooded—mammals and birds. In small mammals, the QT interval is short, and local ventricular recordings reveal early repolarization that coincides with the J‐wave on the ECG, a positive ...

Brain transcriptome of the violet-eared waxbill Uraeginthus granatina and recent evolution in the songbird genome [PDF]

Open Biology, 2013
Songbirds are important models for the study of social behaviour and communication. To complement the recent genome sequencing of the domesticated zebra finch, we sequenced the brain transcriptome of a closely related songbird species, the violet-eared ...

DNA Methylation Regulates Transcription Factor-Specific Neurodevelopmental but Not Sexually Dimorphic Gene Expression Dynamics in Zebra Finch Telencephalon

Frontiers in Cell and Developmental Biology, 2021
Song learning in zebra finches (Taeniopygia guttata) is a prototypical example of a complex learned behavior, yet knowledge of the underlying molecular processes is limited. Therefore, we characterized transcriptomic (RNA-sequencing) and epigenomic (RRBS,

Induction of an immortalized songbird cell line allows for gene characterization and knockout by CRISPR-Cas9

Scientific Reports, 2022
The zebra finch is one of the most commonly studied songbirds in biology, particularly in genomics, neuroscience and vocal communication. However, this species lacks a robust cell line for molecular biology research and reagent optimization. We generated

Long-term Devocalization of Zebra Finches [PDF]

BIO-PROTOCOL, 2020
Songbirds, such as the zebra finch, are a popular animal model for studying the neural basis of vocal and complex skill learning. Adult male zebra finches produce courtship song toward females (referred to as 'directed song') and recording and analyzing sounds of directed song along with underlying neural activity is important for investigating ...

The zebra finch neuropeptidome: prediction, detection and expression

BMC Biology, 2010
Background Among songbirds, the zebra finch (Taeniopygia guttata) is an excellent model system for investigating the neural mechanisms underlying complex behaviours such as vocal communication, learning and social interactions.

Comparative genomic analysis of the zebra finch degradome provides new insights into evolution of proteases in birds and mammals

BMC Genomics, 2010
Background The degradome -the complete repertoire of proteases in an organism- is involved in multiple key biological and pathological processes. Previous studies in several organisms have yielded sets of curated protease sequences which may be used to ...

Base composition is the primary factor responsible for the variation of amino acid usage in zebra finch (Taeniopygia guttata).

PLoS ONE, 2018
In the present study, we carried out an examination of the amino acid usage in the zebra finch (Taeniopygia guttata) proteome. We found that tRNA abundance, base composition, hydrophobicity and aromaticity, protein second structure, cysteine residue (Cys)

Relative Water Economy Is a Useful Index of Aridity Tolerance for Australian Poephiline Finches

Birds, 2022
We evaluate if the iconic Australian Zebra Finch (Taeniopygia guttata) has a unique physiology or if its metabolic, thermal and hygric physiology are similar to other Australian poephiline finches, by comparing it with three other species, the arid ...
