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 ...

Ecological genomics of Boechera stricta: identification of a QTL controlling the allocation of methionine- vs branched-chain amino acid-derived glucosinolates and levels of insect herbivory. [PDF]
Heredity (Edinb), 2009 In the Brassicaceae, glucosinolates influence the feeding, reproduction and development of many insect herbivores. Glucosinolate production and effects on herbivore feeding have been extensively studied in the model species, Arabidopsis thaliana and Brassica crops, both of which constitutively produce leaf glucosinolates mostly derived from the amino ...

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.

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 ...

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

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.

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 ...

Globally Relaxed Selection and Local Adaptation in Boechera stricta. [PDF]
Genome Biol Evol, 2022 AbstractThe strength of selection varies among populations and across the genome, but the determinants of efficacy of selection remain unclear. In this study, we used whole-genome sequencing data from 467 Boechera stricta accessions to quantify the strength of selection and characterize the pattern of local adaptation. We found low genetic diversity on

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)

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 ...
