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.

Complex trait divergence contributes to environmental niche differentiation in ecological speciation of Boechera stricta [PDF]
Molecular Ecology, 2013 AbstractEcological factors may contribute to reproductive isolation if differential local adaptation causes immigrant or hybrid fitness reduction. Because local adaptation results from the interaction between natural selection and adaptive traits, it is crucial to investigate both to understand ecological speciation. Previously, we used niche modelling

Variation and fitness costs for tolerance to different types of herbivore damage in Boechera stricta genotypes with contrasting glucosinolate structures [PDF]
New Phytologist, 2010 • Analyses of plant tolerance in response to different modes of herbivory are essential to an understanding of plant defense evolution, yet are still scarce. Allocation costs and trade-offs between tolerance and plant chemical defenses may influence genetic variation for tolerance.

The ecological, genetic and genomic architecture of local adaptation and population differentiation in Boechera stricta. [PDF]
Proc Biol Sci, 2021 Differential local adaptation restricts gene flow between populations inhabiting distinct environments, resulting in isolation by adaptation. In addition to the statistical inferences of genotype–environment associations, an integrative approach is needed to investigate the effect of local adaptation on population divergence at the ecological, genetic ...

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.

Costs of reproduction under experimental climate change across elevations in the perennial forb Boechera stricta. [PDF]
Proc Biol Sci, 2021 Investment in current reproduction can reduce future fitness by depleting resources needed for maintenance, particularly under environmental stress. These trade-offs influence life-history evolution. We tested whether climate change alters the future-fitness costs of current reproduction in a large-scale field experiment ofBoechera stricta(Brassicaceae)

Phylogenetic and Expression Analysis of CENH3 and APOLLO Genes in Sexual and Apomictic Boechera Species [PDF]
Plants, 2022 Apomictic plants (reproducing via asexual seeds), unlike sexual individuals, avoid meiosis and egg cell fertilization. Consequently, apomixis is very important for fixing maternal genotypes in the next plant generations. Despite the progress in the study

Plasticity of plant defense and its evolutionary implications in wild populations of Boechera stricta. [PDF]
Evolution, 2018 Abstract Phenotypic 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).

Natural quantitative genetic variance in plant growth differs in response to ecologically relevant temperature heterogeneity [PDF]
Ecology and Evolution, 2016 Adaptation to large‐scale spatial heterogeneity in the environment accounts for a major proportion of genetic diversity within species. Theory predicts the erosion of adaptive genetic variation on a within‐population level, but considerable genetic ...

Cloning and Functional Analysis of three Cold Regulated CBF Genes in the Overwintering Crucifer Boechera stricta [PDF]
International Journal of Agriculture and Biology, 2018 In this research, we isolated three CBF (C-repeat-Binding Factors) genes from two genotypes of Boechera stricta with contrasting freezing tolerance and characterized their structure and expression patterns in response to cold treatment.
