Freshwater Sponges Have Functional, Sealing Epithelia with High Transepithelial Resistance and Negative Transepithelial Potential
Download2010
Leys, S.P., Goss, G.G., Adams, E.D.M.
Epithelial tissue — the sealed and polarized layer of cells that regulates transport of ions and solutes between the environment and the internal milieu — is a defining characteristic of the Eumetazoa. Sponges, the most ancient metazoan phylum [1], [2], are generally believed to lack true...

Li, R., Wang, J., Wong, G.K.S., Zheng, H., Xu, S., Clark, T., Zheng, X., Vang, S.
Background Gene conversion causes a non-reciprocal transfer of genetic information between similar sequences. Gene conversion can both homogenize genes and recruit point mutations thereby shaping the evolution of multigene families. In the rice genome, the large number of duplicated genes...

Gene expression and sensory structures in sponges: Explorations of sensory-neural origins in a non-bilaterian context
DownloadFall 2017
The nervous system is present in all but two animal phyla – one of them being Porifera, sponges. Sponges have no neurons and yet have organized behavior and finely tuned sensation. Furthermore, sponges have genes involved in the nervous system of other animals (informally called ‘neural’ genes)....

Genetic diversity and selection in North American red squirrels (Tamiasciurus hudsonicus): A Hamiltonian perspective into the processes and mechanisms of evolution
DownloadFall 2013
The theory of natural selection has advanced our understanding in every aspect of biological sciences, yet despite this seeming ubiquity, there remain some components that are not fully resolved. Natural selection predicts the “selfish” advancement of genes that are optimally suited for their...

Wang, W., Li, J., Liu, D., Lu, Z., Zheng, H., Wong, G., Cai, Z., Fan, C., Zhang, J., Vang, S., Long, M., Zhang, G., Wang, J., Shi, J.
Retroposition is widely found to play essential roles in origination of new mammalian and other animal genes. However, the scarcity of retrogenes in plants has led to the assumption that plant genomes rarely evolve new gene duplicates by retroposition, despite abundant retrotransposons in plants...

High resolution radiation hybrid maps of bovine chromosome 19 and 29 and comparison with the bovine genome sequence assembly
Download2007
Murdoch, B., Wang, Z., Stothard, P., Womack, J. E., Mckay, S. D., Moore, S. S., Schiex, T., Prasad, A.
Background High resolution radiation hybrid (RH) maps can facilitate genome sequence assembly by correctly ordering genes and genetic markers along chromosomes. The objective of the present study was to generate high resolution RH maps of bovine chromosomes 19 (BTA19) and 29 (BTA29), and...

Seligmann, B., Deyholos, M., Kris, R. M., Felder, S., Botros, I., Galbraith, D. W., Martel, R., Hinton, J., Lambert, G. M.
High-throughput gene expression analysis of genes expressed during salt stress was performed using a novel multiplexed quantitative nuclease protection assay that involves customized DNA microarrays printed within the individual wells of 96-well plates. The levels of expression of the transcripts...

Hymenolepis diminuta (Cestoda) induces changes in expression of select genes of Tribolium confusum (Coleoptera)
Download2009
Belosevic, M., Shostak, A. W., Hitchen, S. J.
The flour beetle Tribolium confusum is a common experimental intermediate host for the tapeworm Hymenolepis diminuta, but while many aspects of their host-parasite interactions have been determined to have genetic basis, the genes involved have not been identified. In this paper, we report on the...
