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]
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]
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 ...

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
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]
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]
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.

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]
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

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 ...
