Faculty members located in academic
departments/centers can be formally associated with the IGBB in two
different ways:
1. IGBB Fellows
Through its Fellows Program, the
IGBB rewards those faculty who have worked within the IGBB to build a
strong, vibrant molecular biosciences/computational biology research
community at MS State. IGBB Fellows receive not only formal recognition
for their accomplishments, but they are given a voice in many aspects of
IGBB operation including, but not limited to, input on purchases, new hires,
and overall research direction. The IGBB Fellows literally serve as
the Director's Advisory Committee. To be an IGBB Fellow, a faculty member from an academic department
must (1) regularly submit proposals through the IGBB, (2) have had at least one funded external grant (with overhead)
administered through the IGBB, (3) have a record of high-impact scientific
productivity, and (4) have a national/international reputation in his/her
field. IGBB Fellows have full "internal user" access to the HPC² supercomputers and receive HPC²
computer, technical, and administrative support.
2. IGBB Faculty Affiliates
An IGBB Faculty Affiliate is any faculty member in an MS State academic department who (1) conducts research
in the molecular biosciences and/or computational biology and (2) collaborates in some manner with IGBB faculty/staff. Like IGBB Fellows, IGBB Faculty Affiliates are encouraged to submit proposals through the IGBB, but
are not obligated to do so. IGBB Faculty Affiliates generally do not
have HPC² supercomputer access unless they are working on an IGBB
research project. Faculty Affiliates can request access to the HPC²
supercomputers if they are interested in generating data/results for an eventual proposal submission
through the IGBB. Any IGBB Faculty Affiliate that submits and receives an external grant (with
overhead) through the IGBB will be eligible for the IGBB Fellows Program.

DOWNLOAD PDFABSTRACTIt has been hypothesized that two successive rounds of whole-genome duplication (WGD) in the stem lineage of vertebrates provided genetic raw materials for the evolutionary innovation of many vertebrate-specific features. However, it has seldom been possible to trace such innovations to specific functional differences between paralogous gene products that derive from a WGD event. Here, we report genomic evidence for a direct link between WGD and key physiological innovations in the vertebrate oxygen transport system. Specifically, we demonstrate that key globin proteins that evolved specialized functions in different aspects of oxidative metabolism (hemoglobin, myoglobin, and cytoglobin) represent paralogous products of two WGD events in the vertebrate common ancestor. Analysis of conserved macrosynteny between the genomes of vertebrates and amphioxus (subphylum Cephalochordata) revealed that homologous chromosomal segments defined by myoglobin + globin-E, cytoglobin, and the alpha-globin gene cluster each descend from the same linkage group in the reconstructed proto-karyotype of the chordate common ancestor. The physiological division of labor between the oxygen transport function of hemoglobin and the oxygen storage function of myoglobin played a pivotal role in the evolution of aerobic energy metabolism, supporting the hypothesis that WGDs helped fuel key innovations in vertebrate evolution.
