Phenotypic variation is traditionally parsed into components that are directed by genetic and
environmental variation. The line between these two components is blurred by inherited …

Mutation accumulation (MA) experiments, in which mutations are allowed to drift to fixation in
inbred lines, have been a principal way of studying the rates and properties of new …

Knowledge of the rate and nature of spontaneous mutation is fundamental to understanding
evolutionary and molecular processes. In this report, we analyze spontaneous mutations …

To take complete advantage of information on within-species polymorphism and divergence
from close relatives, one needs to know the rate and the molecular spectrum of spontaneous …

Despite the central importance of noncoding DNA to gene regulation and evolution,
understanding of the extent of selection on plant noncoding DNA remains limited compared …

A basic knowledge about mutation rates is central to our understanding of a myriad of
evolutionary phenomena, including the maintenance of sex and rates of molecular …

Mutations spawn genetic variation which, in turn, fuels evolution. Hence, experimental
investigations into the rate and fitness effects of spontaneous mutations are central to the …

Although certain acquired nongenetic (ie, epigenetic) traits are known to be heritable in
plants, little is known currently about whether environmental parameters can induce …

Despite many years of theoretical and experimental work, the explanation for why sex is so
common as a reproductive strategy continues to resist understanding. Recent empirical work …

There is abundant evidence that environments have shifted dramatically in biotic makeup
and climatic conditions during the recent geological past (Davis 1983, Pitelka and Plant …
