Differences in ploidy levels of interploidal crosses progenies between diploids and tetraploid somatic hybrids in citrus : S02P19 [PDF]

, 2012
One of the main objectives of citrus breeders is to obtain sterile mandarins that produce seedless fruits. Triploids are a response to these criteria. A way for triploid creation is sexual crosses between diploids and tetraploids.

A comparison of calcification mechanisms in haploid and diploid cells of the coccolithophore Calcidiscus leptoporus (Murray & Blackman 1898)

Journal of Phycology, EarlyView.
Abstract Coccolithophores are prominent marine pelagic calcifiers due to their production of calcite coccoliths. Diploid coccolithophores produce heterococcoliths intracellularly, with an organic cellulose baseplate scale acting as a nucleating substrate. However, coccolith production in the haploid life phase has not been extensively studied.

Impacts of climatic niche breadth, phylogeny, traits and ploidy on geographical ranges of Betula species

Journal of Systematics and Evolution, EarlyView.
Geographical range size is a fundamental ecological characteristic of a species. We quantified the effects of phylogeny, climatic niche breadth, morphological traits and ploidy on range size variation of Betula species. Climatic niche breadth has the strongest effect on the range size variation of Betula species.

Documenting homoploid hybrid speciation

Molecular Ecology, EarlyView.
Abstract Homoploid hybrid speciation is challenging to document because hybridization can lead to outcomes other than speciation. Thus, some authors have argued that establishment of homoploid hybrid speciation should include evidence that reproductive barriers isolating the hybrid neo‐species from its parental species were derived from hybridization ...

Multiple hybridization events and repeated evolution of homoeologue expression bias in parthenogenetic, polyploid New Zealand stick insects

Molecular Ecology, EarlyView.
Abstract During hybrid speciation, homoeologues combine in a single genome. Homoeologue expression bias (HEB) occurs when one homoeologue has higher gene expression than another. HEB has been well characterized in plants but rarely investigated in animals, especially invertebrates.

Genomics‐Driven Monitoring of Fraxinus latifolia (Oregon Ash) to Inform Conservation and EAB‐Resistance Breeding

Molecular Ecology, EarlyView.
ABSTRACT Understanding the evolutionary processes underlying range‐wide genomic variation is critical to designing effective conservation and restoration strategies. Evaluating the influence of connectivity, demographic change and environmental adaptation for threatened species can be invaluable to proactive conservation of evolutionary potential.

Whole‐Genome Sequencing and Phenotyping Reveal Specific Adaptations of Lachancea thermotolerans to the Winemaking Environment

Molecular Ecology, EarlyView.
ABSTRACT Adaptation to the environment plays an essential role in yeast evolution as a consequence of selective pressures. Lachancea thermotolerans, a yeast related to fermentation and one of the current trends in wine technology research, has undergone an anthropisation process, leading to a notable genomic and phenomic differentiation.

The Roles of Plasticity and Selection in Rapid Phenotypic Changes at the Pacific Oyster Invasion Front in Europe

Molecular Ecology, EarlyView.
ABSTRACT Invasive species present significant management challenges worldwide due to their ability to rapidly adapt to novel environments. The Pacific oyster Crassostrea gigas, a globally distributed invasive species, arrived in western Sweden in 2006 but has not yet colonised the low salinity waters of the Baltic Sea, presumably because low salinities

Translational control by the multi-KH domain protein Scp160 [PDF]

, 2010
The control of mRNA translation mediated by RNA-binding proteins (RBPs) is a key player in modulating gene expression. In S. cerevisiae, the multi-KH domain protein Scp160 associates with a large number of mRNAs and is present on membrane-bound and, to a

Mixed Outcomes in Recombination Rates After Domestication: Revisiting Theory and Data

Molecular Ecology, EarlyView.
ABSTRACT The process of domestication has altered many phenotypes. Selection on these phenotypes has long been hypothesised to indirectly select for increases in the genome‐wide recombination rate. This hypothesis is potentially consistent with theory on the evolution of the recombination rate, but empirical support has been unclear. We review relevant
