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

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.

Rhizosphere microbiomes of field-grown B. stricta exhibit minimal diel changes in microbial membership and protein synthesis potential [PDF]
Frontiers in MicrobiologyThe rhizosphere microbiome has a significant impact on plant health and fitness. Quantifying bacterial responses to fine-scale plant-mediated changes in the rhizosphere, such as those associated with diel cycling in host plant physiology, will increase ...

Host genotype and age shape the leaf and root microbiomes of a wild perennial plant [PDF]
Nature Communications, 2016 Laboratory-based studies of the effect of plant genotype on plant microbiome composition often do not consider the influence of environmental heterogeneity. Here, Wagner et al.

Rhizosphere microbial community composition shifts diurnally and in response to natural variation in host clock phenotype [PDF]
mSystems, 2023 Plant-associated microbial assemblages are known to shift at time scales aligned with plant phenology, as influenced by the changes in plant-derived nutrient concentrations and abiotic conditions observed over a growing season. But these same factors can

A comparison of 16S rRNA-gene and 16S rRNA-transcript derived microbial communities in bulk and rhizosphere soils [PDF]
Frontiers in MicrobiologyRoot exudates in a plant’s rhizosphere alters microbial community membership and activity, which can in turn alter a plant’s health and fitness. In this study we characterized bacterial community composition, using 16S rRNA-gene (DNA) sequencing to ...

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

Identification of quantitative trait loci and a candidate locus for freezing tolerance in controlled and outdoor environments in the overwintering crucifer Boechera stricta. [PDF]
Plant Cell Environ, 2014 AbstractDevelopment of chilling and freezing tolerance is complex and can be affected by photoperiod, temperature and photosynthetic performance; however, there has been limited research on the interaction of these three factors. We evaluated 108 recombinant inbred lines of Boechera stricta, derived from a cross between lines originating from Montana ...

Increasing Aridity May Threaten the Maintenance of a Plant Defence Polymorphism. [PDF]
Ecol LettIt is unclear how environmental change influences standing genetic variation in wild populations. Here, we characterised environmental conditions that protect versus erode polymorphic chemical defences in Boechera stricta (Brassicaceae), a short-lived ...

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits. [PDF]
Ecol EvolThis systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.
