Extensive Genomic Variation within Clonal Complexes of Neisseria meningitidis [PDF]

Genome Biology and Evolution, 2011
Meningococcal disease is a widely distributed complex disease affecting all age categories. It can cause severe meningitis and septicemia, especially in unvaccinated infants and young children. The causative agent, Neisseria meningitidis (Nm), can be phenotypically and genetically differentiated into serogroups and sequence types (STs) and has a highly

Inter- and intraclonal variability in the photoperiodic response and fecundity in the pea aphid Acyrthosiphon pisum (Hemiptera: Aphididae)

European Journal of Entomology, 2003
Interclonal variability in the photoperiodic responses of the pea aphid Acyrthosiphon pisum and intraclonal differences between wingless viviparous females (=apterae) and winged viviparous females (=alatae) were studied.

Genet-specific DNA methylation probabilities detected in a spatial epigenetic analysis of a clonal plant population. [PDF]

PLoS ONE, 2017
In sessile organisms such as plants, spatial genetic structures of populations show long-lasting patterns. These structures have been analyzed across diverse taxa to understand the processes that determine the genetic makeup of organismal populations ...

Long-term colonization of the cystic fibrosis lung by Burkholderia cepacia complex bacteria: epidemiology, clonal variation and genome-wide expression alterations

Frontiers in Cellular and Infection Microbiology, 2011
Long-term respiratory infections with Burkholderia cepacia complex (Bcc) bacteria in cystic fibrosis (CF) patients generally lead to a more rapid decline in lung function and, in some cases, to a fatal necrotizing pneumonia known as the cepacia syndrome.

Variation in gene expression within clones of the earthworm Dendrobaena octaedra. [PDF]

PLoS ONE, 2017
Gene expression is highly plastic, which can help organisms to both acclimate and adapt to changing environments. Possible variation in gene expression among individuals with the same genotype (among clones) is not widely considered, even though it could

Both Adaptability and Endophytic Bacteria Are Linked to the Functional Traits in the Invasive Clonal Plant Wedelia trilobata

Plants, 2022
The role of the interactions between endophytes and host plants is unclear in invasive plants from different geographical latitudes. In this study, we aimed to explore the relationship between endophytic microbes and the functional traits of the invasive

Epigenetic variation in clonal stands of aspen

Folia Geobotanica, 2017
Epigenetic mechanisms can affect ecologically important traits, even in the absence of genetic variation. Environmental factors can influence gene regulation through chemical modifications, such as DNA methylation, resulting in acclimation that can be transferred to subsequent cell generations both mitotically and meiotically.

TERRA Expression Levels Do Not Correlate With Telomere Length and Radiation Sensitivity in Human Cancer Cell Lines

Frontiers in Oncology, 2013
Mammalian telomeres are transcribed into long non-coding telomeric RNA molecules (TERRA) that seem to play a role in the maintenance of telomere stability.

The effects of fertility and synchronization variation on seed production in two Chinese fir clonal seed orchards

Scientific Reports, 2023
Variations in fertility and synchronization information is fundamental to seed orchard management. Our objective was to determine clonal variation and stability in strobili production, phenology, synchronization, and seed production in two generation ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
