Quantitative variation for apomictic reproduction in the genus Boechera (Brassicaceae) [PDF]

American Journal of Botany, 2010
• Premise of the study: The evolution of asexual seed production (apomixis) from sexual relatives is a great enigma of plant biology. The genus Boechera is ideal for studying apomixis because of its close relation to Arabidopsis and the occurrence of sexual and apomictic species at low ploidy levels (diploid and triploid).

Boechera or not? Genomic insights and taxonomic reassessment of the misclassified Asian species B. calcarea (Brassicaceae)

Plant Diversity
The genus Boechera (Brassicaceae) serves as a model system for studying apomictic reproduction and ecological adaptations, with most species occurring in North America.

Multiple ITS Copies Reveal Extensive Hybridization within Rheum (Polygonaceae), a Genus That Has Undergone Rapid Radiation [PDF]

, 2014
During adaptive radiation events, characters can arise multiple times due to parallel evolution, but transfer of traits through hybridization provides an alternative explanation for the same character appearing in apparently non-sister lineages.

Comparative Genetic Mapping inBoechera stricta, a Close Relative of Arabidopsis [PDF]

Plant Physiology, 2007
AbstractThe angiosperm family Brassicaceae contains both the research model Arabidopsis (Arabidopsis thaliana) and the agricultural genus Brassica. Comparative genomics in the Brassicaceae has largely focused on direct comparisons between Arabidopsis and the species of interest.

Influences of plant maternal effects, chemotype, and environment on the leaf bacterial community. [PDF]

Plant Biol (Stuttg)
Plant maternal effects and growth environment, rather than terpenoid chemotype, determine the leaf microbial community of Tanacetum vulgare, but specific terpenoids are correlated with the abundance of certain bacteria. Abstract Plant individuals within a species can differ markedly in their leaf chemical composition, forming so‐called chemotypes ...

Genetic mechanisms of pollution resistance in a marine invertebrate [PDF]

, 2007
Pollution is a common stress in the marine environment and one of today's most powerful agents of selection, yet we have little understanding of how anthropogenic toxicants influence mechanisms of adaptation in marine populations.

Host genotype and age shape the leaf and root microbiomes of a wild perennial plant

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.

Apomictic and sexual germline development differ with respect to cell cycle, transcriptional, hormonal and epigenetic regulation. [PDF]

PLoS Genetics, 2014
Seeds of flowering plants can be formed sexually or asexually through apomixis. Apomixis occurs in about 400 species and is of great interest for agriculture as it produces clonal offspring. It differs from sexual reproduction in three major aspects: (1)

Sexual reproduction, hybridization, apomixis, and polyploidization in the genus Boechera (Brassicaceae) [PDF]

American Journal of Botany, 2005
Of the 340 genera in the Brassicaceae, apomictic reproduction is found only in the North American genus Boechera. We investigated phylogenetic relationships, ability to hybridize, mating system, and ploidy levels of 92 lines sampled from 85 populations and representing 19 Boechera species.
