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.

A general statistical framework for dissecting parent-of-origin effects underlying endosperm traits in flowering plants

, 2010
Genomic imprinting has been thought to play an important role in seed development in flowering plants. Seed in a flowering plant normally contains diploid embryo and triploid endosperm.

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

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

Contrasting Evolutionary Trajectories Under Paternal Genome Elimination in Male and Female Citrus Mealybugs

Molecular Ecology, EarlyView.
ABSTRACT Most studies of sex‐biased genes explore their evolution in familiar chromosomal sex determination systems, leaving the evolution of sex differences under alternative reproductive systems unknown. Here we explore the system of paternal genome elimination employed by mealybugs (Hemiptera: Pseudococcidae) which have no sex chromosomes.

Establishment and Optimization of an Experiment System for Flow Cytometry in Oil-Seed Camellia

Horticulturae
Ploidy identification is a basic method for determining germplasm resources and for breeding new varieties of oil-seed camellia. In this study, flow cytometry and K-mer analysis were used to identify the ploidy of oil-seed camellia germplasms.

A Comparison of Diploid and Triploid Eastern Oysters for Aquaculture Production Under Extreme Temperatures and Salinities [PDF]

Off-bottom aquaculture of Eastern oysters (Crassostrea virginica) is a nascent industry that is increasingly supported by the use of triploid oysters, which grow faster than diploids.

Uncovering the reciprocal effects of plant polyploidy and the microbiome: implications for understanding of polyploid success

New Phytologist, EarlyView.
Summary Polyploidy plays a major role in diversification and speciation of almost all plants. Separately, the microbiome is recognized for its ubiquitous role in plant functioning. Despite the importance of both processes, we lack a synthetic picture of their reciprocal relationship.
