Selection of reference genes for quantitative real-time PCR expression studies of microdissected reproductive tissues in apomictic and sexual Boechera [PDF]
, 2011 Background Apomixis, a natural form of asexual seed production in plants, is considered to have great biotechnological potential for agriculture. It has been hypothesised that de-regulation of the sexual developmental pathway could trigger apomictic ...

Admixture, evolution, and variation in reproductive isolation in the Boechera puberula clade
BMC Evolutionary Biology, 2018 Background Hybridization is very common in plants, and the incorporation of new alleles into existing lineages (i.e. admixture) can blur species boundaries. However, admixture also has the potential to increase standing genetic variation.

Ecological causes and consequences of flower color polymorphism in a self‐pollinating plant (Boechera stricta) [PDF]
New Phytologist, 2018 SummaryIntraspecific variation in flower color is often attributed to pollinator‐mediated selection, yet this mechanism cannot explain flower color polymorphisms in self‐pollinating species. Indirect selection mediated via biotic and abiotic stresses could maintain flower color variation in these systems.The selfing forb,Boechera stricta, typically ...

The genome sequence of Barbarea vulgaris facilitates the study of ecological biochemistry [PDF]
, 2017 peer-reviewedThe genus Barbarea has emerged as a model for evolution and ecology of plant defense compounds, due to its unusual glucosinolate profile and production of saponins, unique to the Brassicaceae. One species, B.

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.
