Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Association studies of up to 1.2 million individuals yield new insights into the genetic etiology of tobacco and alcohol use. [PDF]

, 2019
Tobacco and alcohol use are leading causes of mortality that influence risk for many complex diseases and disorders1. They are heritable2,3 and etiologically related4,5 behaviors that have been resistant to gene discovery efforts6-11.

Temperature and the evolution of flower color: A review

American Journal of Botany, EarlyView.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Reliable heritability estimation using sparse regularization in ultrahigh dimensional genome-wide association studies

BMC Bioinformatics, 2019
Background Data from genome-wide association studies (GWASs) have been used to estimate the heritability of human complex traits in recent years. Existing methods are based on the linear mixed model, with the assumption that the genetic effects are ...

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone

American Journal of Botany, EarlyView.
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...

Fast model-fitting of Bayesian variable selection regression using the iterative complex factorization algorithm

, 2018
Bayesian variable selection regression (BVSR) is able to jointly analyze genome-wide genetic datasets, but the slow computation via Markov chain Monte Carlo (MCMC) hampered its wide-spread usage.

Molecular Profiling of Genes Associated With Methylphenidate Pathway Therapy and Discovery of New Variants in Amazonian Amerindian Populations

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT In Attention Deficit Hyperactivity Disorder (ADHD), methylphenidate is one of the most widely used drugs, in which patient response significantly impacts prognosis. This study aimed to characterize the molecular profile of 10 genes associated with methylphenidate therapy.

The Heritable Effects of Nanotoxicity

Nanomedicine, 2014
The widespread entry of nanomaterials into manifold life fields posed serious concerns on environmental health and safety issues. Potential adverse effects of nanoparticles (NPs) are continuously faced using in vitro cell systems and by mean of cell and molecular biology tools, several mechanisms have been found beyond their toxicity. The evaluation of
