Establishing the cell biology of apomictic reproduction in diploid Boechera stricta (Brassicaceae). [PDF]
Ann Bot, 2018 In the Brassicaceae family, apomictic development is characteristic of the genus Boechera. Hybridization, polyploidy and environmental adaptation that arose during the evolution of Boechera may serve as (epi)genetic regulators of apomictic initiation in this genus.

Plasticity of plant defense and its evolutionary implications in wild populations of Boechera stricta. [PDF]
Evolution, 2018 AbstractPhenotypic plasticity is thought to impact evolutionary trajectories by shifting trait values in a direction that is either favored by natural selection (“adaptive plasticity”) or disfavored (“nonadaptive” plasticity). However, it is unclear how commonly each of these types of plasticity occurs in natural populations.

Microgeographic Patterns of Genetic Divergence and Adaptation across Environmental Gradients in Boechera stricta (Brassicaceae). [PDF]
Am Nat, 2015 Abiotic and biotic conditions often vary continuously across the landscape, imposing divergent selection on local populations. We used a provenance trial approach to examine microgeographic variation in local adaptation in Boechera stricta (Brassicaceae), a perennial forb native to the Rocky Mountains.

Life-history QTLS and natural selection on flowering time in Boechera stricta, a perennial relative of Arabidopsis. [PDF]
Evolution, 2011 Plants must precisely time flowering to capitalize on favorable conditions. Although we know a great deal about the genetic basis of flowering phenology in model species under controlled conditions, the genetic architecture of this ecologically important trait is poorly understood in nonmodel organisms. Here, we evaluated the transition from vegetative

Herbivory and water availability interact to shape the adaptive landscape in the perennial forb, Boechera stricta. [PDF]
EvolutionAbstract Abiotic and biotic factors interact to influence phenotypic evolution; however, identifying the causal agents of selection that drive the evolution and expression of traits remains challenging. In a field common garden, we manipulated water availability and herbivore abundance across 3 years, and evaluated clinal variation in ...

Multilocus patterns of nucleotide diversity, population structure and linkage disequilibrium in Boechera stricta, a wild relative of Arabidopsis. [PDF]
Genetics, 2009 AbstractInformation about polymorphism, population structure, and linkage disequilibrium (LD) is crucial for association studies of complex trait variation. However, most genomewide studies have focused on model systems, with very few analyses of undisturbed natural populations.

Largest genome assembly in Brassicaceae: retrotransposon-driven genome expansion and karyotype evolution in Matthiola incana. [PDF]
Plant Biotechnol JSummary 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.

Comparative Genetic Mapping inBoechera stricta, a Close Relative of Arabidopsis [PDF]
Plant Physiology, 2007 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
Phytobiomes Journal, 2021 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
