Transcriptomics
- Help, there are ‘omics’ in my comparative physiology!
Summary: Practical advice for successful design and implementation of omics-based experiments and interpretation of the resulting data to evaluate and test hypotheses in comparative physiology.
- The ghost of temperature past: interactive effects of previous and current thermal conditions on gene expression in Manduca sexta
Summary: Repeated high temperature exposure has diverse consequences for gene expression patterns in two recently diverged populations of Manduca sexta, leading to thermal acclimation or increased stress responses.
- Variable vision in variable environments: the visual system of an invasive cichlid (Cichla monoculus) in Lake Gatun, Panama
Summary: Examination of the visual system plasticity of the peacock bass, Cichla monoculus, shows that this species adapts to a changing environment by alternating the use of chromophores A1 and A2, and through differential gene expression in the retina.
- Identification of novel circadian transcripts in the zebrafish retina
Summary: Characterization of the day and night transcriptome of the adult zebrafish retina reveals novel circadian transcripts.
- Exposure to CO2 influences metabolism, calcification and gene expression of the thecosome pteropod Limacina retroversa
Summary: Severity and duration of CO2 exposure influence calcification and respiration differentially in Limacina retroversa, as shown by organismal and gene expression responses, while captivity interactively influences respiration and gene expression.
- Cognitive specialization for learning faces is associated with shifts in the brain transcriptome of a social wasp
Highlighted Article: Comparative brain transcriptomics of Polistes paper wasps identifies molecular mechanisms associated with individual facial recognition, which function in neural signaling and signal transduction.
- Effects of high temperatures on threatened estuarine fishes during periods of extreme drought
Highlighted Article: An integrative approach to assess the impact of elevated water temperature on fishes of immediate conservation concern highlights the vulnerability of longfin smelt relative to delta smelt.
- Diet and endocrine effects on behavioral maturation-related gene expression in the pars intercerebralis of the honey bee brain
Summary: Transcriptomic profiling of the pars intercerebralis in the honey bee brain provides mechanistic insights into how neurosecretory signals mediate social behavior.
- The environmentally tuned transcriptomes of Mytilus mussels
Summary: Abiotic factors, such as temperature and the tidal cycle, drive patterns of gene expression in Mytilus mussels that underlie whole-organism physiological states, which, in turn, influence biogeographic distributions.
- Considerations for the use of transcriptomics in identifying the ‘genes that matter’ for environmental adaptation
Summary: The ability of transcriptomics to identify genes that underlie environmental adaptation is explored in the context of recent systems-level experiments that provide new insights into the relationship between gene expression and fitness.
