Genomic and neural analysis of the estradiol-synthetic pathway in the zebra finch

Editor’s summary
Estrogenic steroid-related genes in the zebra finch and other mammals are largely homologous, but steroidogenic enzyme genes might be less diverse in the finch and the neural expression of a cholesterol transport protein gene might be regulated by hearing song.

Gene duplication and fragmentation in the zebra finch major histocompatibility complex
Christopher N Balakrishnan, Robert Ekblom, Martin Völker, Helena Westerdahl, Ricardo Godinez, Holly Kotkiewicz, David W Burt, Tina Graves, Darren K Griffin, Wesley C Warren, Scott V Edwards BMC Biology 2010, 8:29 (1 April 2010)

|
Editor’s summary
The Zebra finch possesses a more complex major histocompatibility complex (MHC) from that of other birds, which is probably the result of genomic changes such as gene duplication, pseudogenization and the distribution of MHC genes on multiple chromosomes.

The zebra finch neuropeptidome: prediction, detection and expression
Fang Xie, Sarah E London, Bruce R Southey, Suresh P Annangudi, Andinet Amare, Sandra L Rodriguez-Zas, David F Clayton, Jonathan V Sweedler BMC Biology 2010, 8:28 (1 April 2010)

Editor’s summary
Characterization of neuropeptides and prohormones in the zebra finch reveals detailed knowledge of the components involved in song recognition learning and provides a basis for future studies investigating the neural mechanisms underlying vocal communication and behavior.

Comparative genomic analysis of the zebra finch degradome provides new insights into evolution of proteases in birds and mammals
Víctor Quesada, Gloria Velasco, Xose S Puente, Wesley C Warren, Carlos López-Otín BMC Genomics 2010, 11:220 (1 April 2010)
Abstract | Full text | PDF

|
Editor’s summary
Comparison of the degradomes of birds and mammals using genes identified in the zebra finch, chicken and human genomes shows how biological traits unique to the zebra finch are reflected in the evolution of their proteases.

A comparison of SNPs and microsatellites as linkage mapping markers: lessons from the zebra finch (Taeniopygia guttata)
Alexander D Ball, Jessica Stapley, Deborah A Dawson, Tim R Birkhead, Terry Burke, Jon Slate BMC Genomics 2010, 11:218 (1 April 2010)
Abstract | Full text | PDF

|
Editor’s summary
An improved genetic linkage map for four chromosomes of the zebra finch (Taeniopygia guttata) was built by first using less error-prone single nucleotide polymorphisms to construct a framework map, and then adding microsatellite markers.
