Segmental dataset and whole body expression data do not support the hypothesis that non-random movement is an intrinsic property of Drosophila retrogenes

Autor: Vibranovski Maria D, Zhang Yong E, Kemkemer Claus, VanKuren Nicholas W, Lopes Hedibert F, Karr Timothy L, Long Manyuan

Publikováno v: BMC Evolutionary Biology, Vol 12, Iss 1, p 169 (2012)

Abstract Background Several studies in Drosophila have shown excessive movement of retrogenes from the X chromosome to autosomes, and that these genes are frequently expressed in the testis. This phenomenon has led to several hypotheses invoking natu

Re-analysis of the larval testis data on meiotic sex chromosome inactivation revealed evidence for tissue-specific gene expression related to the drosophila X chromosome

Autor: Vibranovski Maria D, Zhang Yong E, Kemkemer Claus, Lopes Hedibert F, Karr Timothy L, Long Manyuan

Publikováno v: BMC Biology, Vol 10, Iss 1, p 49 (2012)

Abstract Background Meiotic sex chromosome inactivation (MSCI) during spermatogenesis has been proposed as one of the evolutionary driving forces behind both the under-representation of male-biased genes on, and the gene movement out of, the X chromo

Expansion and functional diversification of a leucyl aminopeptidase family that encodes the major protein constituents of Drosophila sperm

Autor: Karr Timothy L, Wilkin Elaine C, Dorus Steve

Publikováno v: BMC Genomics, Vol 12, Iss 1, p 177 (2011)

Abstract Background The evolutionary diversification of gene families through gene creation (and loss) is a dynamic process believed to be critical to the evolution of functional novelty. Previous identification of a closely related family of eight a

Wolbachia: Evolutionary novelty in a rickettsial bacteria

Autor: Anderson Cort L, Karr Timothy L

Publikováno v: BMC Evolutionary Biology, Vol 1, Iss 1, p 10 (2001)

Abstract Background Although closely related, the alpha-proteobacteria Wolbachia and the Rickettsiacae (Rickettsia and Ehrlichia), employ different evolutionary life history strategies. Wolbachia are obligate endocellular symbionts that infect an ext
