Recombination suppression in plant adaptation and speciation. [PDF]
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Comparative Genetic Mapping inBoechera stricta, a Close Relative of Arabidopsis [PDF]
AbstractThe angiosperm family Brassicaceae contains both the research model Arabidopsis (Arabidopsis thaliana) and the agricultural genus Brassica. Comparative genomics in the Brassicaceae has largely focused on direct comparisons between Arabidopsis and the species of interest.

Rhizosphere Microbes Influence Host Circadian Clock Function
The circadian clock is an important determinant of fitness that is entrained by local conditions. Aside from abiotic factors, individual pathogenic soil bacteria affect circadian clock function in plant hosts. Yet, in nature, plants interact with diverse

Variation in circadian rhythms is maintained among and within populations in Boechera stricta [PDF]
AbstractCircadian clocks have evolved independently in all three domains of life, and fitness benefits of a functional clock have been demonstrated in experimental genotypes in controlled conditions. Still, little is known about genetic variation in the clock and its fitness consequences in natural populations from heterogeneous environments.

Largest genome assembly in Brassicaceae: retrotransposon-driven genome expansion and karyotype evolution in Matthiola incana. [PDF]
Summary Matthiola incana, commonly known as stock and gillyflower, is a widely grown ornamental plant whose genome is significantly larger than that of other species in the mustard family. However, the evolutionary history behind such a large genome (~2 Gb) is still unknown.

Intraspecific diversification in North American Boechera stricta (= Arabis drummondii), Boechera ×divaricarpa, and Boechera holboellii (Brassicaceae) inferred from nuclear and chloroplast molecular markers—an integrative approach [PDF]
We performed a combined evolutionary analysis of North American Boechera stricta, Boechera holboellii, and their hybrid Boechera ×divaricarpa using information on ploidy level estimators, allelic microsatellite variation, noncoding regions of the plastidic genome (cpDNA), and sequences of the internal transcribed spacers 1 and 2 of the nuclear ...

The Leading Edge Matters Too: Fitness and the Expression of Adaptive Differentiation Are Greatest at the High-Elevation Edge of a Species' Range. [PDF]
We tested hypotheses about adaptation across elevational range limits in Erythranthe laciniata, a montane plant endemic to the Sierra Nevada. Using common garden experiments, we found highest fitness and strongest climate adaptation at high elevations, suggesting potential for range expansion and challenging assumptions of limited adaptive potential at

Evolutionary processes from the perspective of flowering time diversity. [PDF]
Although it is well appreciated that genetic studies of flowering time regulation have led to fundamental advances in the fields of molecular and developmental biology, the ways in which genetic studies of flowering time diversity have enriched the field

Partial Shotgun Sequencing of the Boechera stricta Genome Reveals Extensive Microsynteny and Promoter Conservation with Arabidopsis [PDF]
Abstract Comparative genomics provides insight into the evolutionary dynamics that shape discrete sequences as well as whole genomes. To advance comparative genomics within the Brassicaceae, we have end sequenced 23,136 medium-sized insert clones from Boechera stricta, a wild relative of Arabidopsis (Arabidopsis thaliana).
