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

open access: yesBMC 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 ...

Comparative Cytogenetics between Two Important Songbird, Models: The Zebra Finch and the Canary. [PDF]

open access: yesPLoS ONE, 2017
Songbird species (order Passeriformes, suborder Oscines) are important models in various experimental fields spanning behavioural genomics to neurobiology.

Testes asymmetry, condition and sexual selection in birds: an experimental test [PDF]

open access: yes, 1998
The functional significance of the marked directional asymmetry in testes size observed in many bird species is obscure. Møller suggested that (i) the smaller of the two testes serves a compensatory role and increases in size (and hence reduces ...

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

open access: yesPLoS 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

open access: yesBirds, 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 ...

Evolution of a cluster of innate immune genes (β-defensins) along the ancestral lines of chicken and zebra finch [PDF]

open access: yes, 2010
BACKGROUND:Avian beta-defensins (AvBDs) represent a group of innate immune genes with broad antimicrobial activity. Within the chicken genome, previous work identified 14 AvBDs in a cluster on chromosome three.

THE GENETIC BASIS OF ZEBRA FINCH VOCALIZATIONS [PDF]

open access: yesEvolution, 2009
Animal vocalizations play an important role in individual recognition, kin recognition, species recognition, and sexual selection. Despite much work in these fields done on birds virtually nothing is known about the heritability of vocal traits in birds.

Susceptibility and Antibody Response of the Laboratory Model Zebra Finch (Taeniopygia guttata) to West Nile Virus.

open access: yesPLoS ONE, 2017
Since the introduction of West Nile virus (WNV) into North America in 1999 a number of passerine bird species have been found to play a role in the amplification of the virus.

Experimental demonstration that offspring fathered by old males have shorter telomeres and reduced lifespans [PDF]

open access: yes, 2018
Offspring of older parents frequently show reduced longevity, but the mechanisms driving this so-called 'Lansing effect' are unknown. While inheritance of short telomeres from older parents could underlie this effect, studies to date in different species

Single-Cell RNA Sequencing Revealed the Heterogeneity of Gonadal Primordial Germ Cells in Zebra Finch (Taeniopygia guttata)

open access: yesFrontiers in Cell and Developmental Biology, 2021
Primordial germ cells (PGCs) are undifferentiated gametes with heterogeneity, an evolutionarily conserved characteristic across various organisms. Although dynamic selection at the level of early germ cell populations is an important biological feature ...
