Rhizosphere microbiomes of field-grown B. stricta exhibit minimal diel changes in microbial membership and protein synthesis potential [PDF]

Frontiers in Microbiology
The 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 ...

Ancient polymorphisms contribute to genome-wide variation by long-term balancing selection and divergent sorting in Boechera stricta

Genome Biology, 2019
Background Genomic variation is widespread, and both neutral and selective processes can generate similar patterns in the genome. These processes are not mutually exclusive, so it is difficult to infer the evolutionary mechanisms that govern population ...

Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle. [PDF]

Plant Biol (Stuttg)
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.

Polyembryonic or Apomictic Seeds Enable Fig Trees to Establish New Populations Without Their Pollinating Wasps, a Case Observation in <i>Ficus gasparriniana</i>. [PDF]

Ecol Evol
Development of apomictic adventitious embry o in Ficus gasparriniana. Apomixis is a key reproductive strategy for F. gasparriniana, especially when pollination by fig wasps is limited. In the absence of pollination, F. gasparriniana produces seeds through adventitious embryos formed within the nucellar tissue, which is accompanied by polyploidization ...

The Functional Change and Deletion of FLC Homologs Contribute to the Evolution of Rapid Flowering in Boechera stricta

Frontiers in Plant Science, 2018
Differences in the timing of vegetative-to-reproductive phase transition have evolved independently and repeatedly in different plant species. Due to their specific biological functions and positions in pathways, some genes are important targets of ...

Establishing the cell biology of apomictic reproduction in diploid Boechera stricta (Brassicaceae) [PDF]

Annals of Botany, 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.

Evolutionary constraint on low elevation range expansion: Defense‐abiotic stress‐tolerance trade‐off in crosses of the ecological model Boechera stricta

Ecology and Evolution, 2019
Most transplant experiments across species geographic range boundaries indicate that adaptation to stressful environments outside the range is often constrained. However, the mechanisms of these constraints remain poorly understood.

On the origin and evolution of apomixis in Boechera [PDF]

Plant Reproduction, 2013
The genetic mechanisms causing seed development by gametophytic apomixis in plants are predominantly unknown. As apomixis is consistently associated with hybridity and polyploidy, these confounding factors may either (a) be the underlying mechanism for the expression of apomixis, or (b) obscure the genetic factors which cause apomixis.
