Abstract Background Many genes produce multiple transcripts due to alternative splicing or utilization of transcription initiation/termination sites. This 'transcriptome expansion' is thought increase phenotypic complexity by allowing a single locus several functionally distinct proteins. However, sex, genetic and developmental variation in the representation has never been examined systematically. Here, we describe genome-wide analysis sex-specific expression Drosophila melanogaster ....
Competition for resources has long been viewed as a key agent of divergent selection. Theory holds that populations facing severe intraspecific competition will tend to use wider range resources, possibly even using entirely novel are less in demand. Yet, there have few experimental tests these ideas. Using the bacterial virus (bacteriophage) ϕ 6 model system, we examined whether host promotes evolution resource use. In laboratory, exhibits narrow but readily produces mutants capable...
Earlier psychophysical and physiological studies, obtained mostly with two-dimensional (2-D) stimuli, provided evidence for the hypothesis that processing of faces differs from scenes. We report on our experiments, employing realistic three-dimensional (3-D) stimuli a hollow mask scene, offer further this hypothesis. The used both scenes were bistable, namely they could elicit either veridical or an illusory volumetric percept. Our results indicate illusion is weakened when are inverted,...
Sexual selection drives faster evolution in males. The X chromosome is potentially an important target for sexual selection, because hemizygosity males permits accumulation of alleles, causing tradeoffs fitness between sexes. Hemizygosity the could cause fundamentally different modes inheritance sexes, with more additive variation and nonadditive females. Indeed, we find that genetic transcriptome primarily but As expected, these differences are pronounced on than autosomes, autosomal loci...
Competition for resources is thought to play a critical role in both the origins and maintenance of biodiversity. Although numerous laboratory evolution experiments have confirmed that competition can be key driver adaptive diversification, few demonstrated its resulting diversity. We investigate conditions favour origin alternative generalist specialist resource-use phenotypes within same population. Previously, we hosts among φ6 bacteriophage mixed novel (non-permissive) ancestral...
ABSTRACT We isolated two environmental phages, as part of the Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Sciences program, that infect Gordonia rubripertincta from topsoil in Lubbock, Texas. report complete genome sequences lytic bacteriophages FlyingTortilla ScarletRaider. Sequence similarity analysis reveals viruses a an unclassified order within Caudoviricetes class.
1. Females from many species assess fluctuating asymmetry (FA; nondirectional deviations symmetry in bilateral traits) when choosing mates. However, the hypothesis that FA indicates quality of a potential mate is controversial because lack consistent evidence conditional or heritable. 2. We present provides information about growth rate swordtail fish Xiphophorus multilineatus, and model for how variation strategies could obscure relationship between stress. 3. Males one genetically...
In order to examine potential trade‐offs in alternative life histories of the high‐backed pygmy swordtail Xiphophorus multilineatus , otoliths were used from wild‐caught males determine if sneaker had advantage maturing earlier natural environments. The sneakers matured significantly than courters, but there was no difference among three courter variants. addition, analyses suggested that effect pituitary locus on size at sexual maturity and growth rates a consequence age maturity. Finally,...
ABSTRACT We isolated three environmental phages that infect Pseudomonas aeruginosa PAO1, an opportunistic pathogen, from Playa Lakes in Lubbock, TX. report the genome sequences of lytic bacteriophages BL1, BL2, and BL3. Sequence similarity analysis revealed viruses belonged to unclassified species genus Pbunavirus within Caudoviricetes .
ABSTRACT Environmental phages infecting Pseudomonas aeruginosa PAK, an opportunistic pathogen, were isolated from playa lakes in Lubbock, TX. We present the genome sequence of three lytic bacteriophages. Upon analysis similarity, we identified viruses as a part unclassified species within genus Pbunavirus Caudoviricetes class.
Abstract Although metagenomics reveals that natural virus communities harbor vast genetic diversity, the spatiotemporal dynamics of viral diversity in wild are seldom tested, especially across small geographic scales. This problem is usefully examined above-ground phyllosphere, because terrestrial plants frequently infected by taxonomically-diverse RNA viruses, whose elevated mutation rates generate abundant allele diversity. Here, we studied comparative analysis samples over time from three...
