Preferential accumulation of sex and Bs chromosomes in biarmed karyotypes by meiotic drive and rates of chromosomal changes in fishes

Tags: , ,
Molina, WFM, P. A.; Bertollo, L. A. C.; Bidau, C. J.,  Anais Da Academia Brasileira De Ciencias,  86:1801-1812. 2014.
Mechanisms of accumulation based on typical centromeric drive or of chromosomes carrying pericentric inversions are adjusted to the general karyotype differentiation in the principal Actinopterygii orders. Here, we show that meiotic drive in fish is also supported by preferential ...

Medusa: A novel gene drive system for confined suppression of insect populations

Tags: ,
Marshall, JMH, B. A.,  PLOS One,  9:e102694. 2014.
Gene drive systems provide novel opportunities for insect population suppression by driving genes that confer a fitness cost into pest or disease vector populations; however regulatory issues arise when genes are capable of spreading across international borders. Gene drive ...

Tags: , , ,
Larracuente, AM,  BMC Evolutionary Biology,  14:233. 2014.

The Trojan Y-Chromosome (TYC) strategy, an autocidal genetic biocontrol method, has been proposed to eliminate invasive alien species. In this work, we analyze the dynamical system model of the TYC strategy, with the aim of studying the viability of the TYC eradication and ...

Combining the Trojan Y chromosome and daughterless carp eradication strategies

J. L. Teem and J. B. Gutierrez,  Biological Invasions,  16:1231-1240. 2013.
The Trojan Y chromosome (TYC) strategy and the daughterless carp (DC) strategy represent two autocidal genetic biocontrol methods for eliminating invasive fish by changing the sex ratio of the population. Each strategy is designed to reduce the number of females in a target ...

J. L. Teem, J. B. Gutierrez and R. D. Parshad,  16,  16:1217-1230. 2013.
Two autocidal genetic biocontrol methods have been proposed as a means to eliminate invasive fish by changing the sex ratio of the population: the Trojan Y Chromosome (TYC) strategy and the Daughterless Carp (DC) strategy. Both strategies were modeled using ordinary differential ...

Elimination of Y chromosome-bearing spermatids during spermiogenesis in an autosomal sex-ratio mutant of Drosophila simulans

Tags: , ,
Yasuno, YI, Y. H.; Yamamoto, M. T.,  Genes & Genetic Systems,  88:113-126. 2013.
Sex ratio distortion, which is commonly abbreviated as sex-ratio, has been studied in many Drosophila species, but the mechanism remains largely unknown. Here, we report on the sex-ratio mutant of D. simulans named excess of females (exf). The third chromosomal recessive mutation ...

Engineering synthetic medea-based and threshold- dependent underdominance-based gene drive systems in mosquitoes

Tags:
Akbari, OM, J.; Antoshechkin, I.; Matzen, K.; Papathanos, P.; Kennedy, K.; Ward, C.; Chen, C. H.; Guo, M.; Hay, B.,  Pathogens and Global Health,  107:442-442. 2013.
Mosquito population replacement requires gene drive mechanisms in order to spread linked genes, mediating disease refractoriness, through wild populations. Medea is predicted to be a low threshold gene drive mechanism, able to spread from low initial frequency. Such a system is ...

Sex-biased gene expression during head development in a sexually dimorphic stalk-eyed fly

Tags:
Wilkinson, GSJ, P. M.; Metheny, J. D.; Baker, R. H.,  PLOS One,  8:1-10. 2013.
Stalk-eyed flies (family Diopsidae) are a model system for studying sexual selection due to the elongated and sexually dimorphic eye-stalks found in many species. These flies are of additional interest because their X chromosome is derived largely from an autosomal arm in other ...

The dynamic relationship between polyandry and selfish genetic elements

Tags: ,
Wedell, N,  Philosophical Transactions of the Royal Society B-Biological Sciences,  368:10. 2013.
Selfish genetic elements (SGEs) are ubiquitous in eukaryotes and bacteria, and make up a large part of the genome. They frequently target sperm to increase their transmission success, but these manipulations are often associated with reduced male fertility. Low fertility of ...
