TAXON, 2009
AbstractThe North American genus Boechera comprises according to current taxonomic classification 110 species. Most of them are centered in western North America, with some species extending from the west into eastern North America and seven exclusively occurring in eastern North America.

Isolation of Boechera stricta Developing Embryos for Hi-C
2022The possibility of analyzing chromatin topology in developing plant embryos is hampered by inaccessibility of the embryo sac, deeply embedded in the maternal seed tissue, following double fertilization. Here we describe a protocol to isolate, purify, and prepare developing Boechera stricta embryos for chromosome conformation capture-based methods as in

Aims. Apomixis is the clonal reproduction of floral plants by seeds without both meiosis and fertilization. Apomixis has great biotechnological benefits in excess of the gain from the ???green revolution??? Norman Borlaug. Nevertheless the genetic control of apomixis is not clear and speculative till now.

Differential effects of polyploidy and diploidy on fitness of apomictic Boechera
Sexual Plant Reproduction, 2012The co-occurrence of apomixis (asexual reproduction) and polyploidy in plants has been the subject of debate in regard to the origin and evolution of asexuality. In recent years, polyploidy has been postulated as a maintenance and stabilization factor rather than as a source of apomixis origin.

Boechera, a model system for ecological genomics.
Molecular ecology, 2012The selection and development of a study system for evolutionary and ecological functional genomics (EEFG) depend on a variety of factors. Here, we present the genus Boechera as an exemplary system with which to address ecological and evolutionary questions. Our focus on Boechera is based on several characteristics as follows: (i) native populations in

Boechera Dentata Is the Correct Name for B. Shortii (Brassicaceae)
Harvard Papers in Botany, 2008ABSTRACT The new combination Boechera dentata is proposed to replace the most commonly used B. shortii or Arabis shortii (Brassicaceae) for a species widespread in eastern and central United States and rare in Ontario, Canada. The complex nomenclatural history of the species is presented.

A new chromosome was born: comparative chromosome painting in Boechera
Trends in Plant Science, 2015Comparative chromosome painting is a powerful tool to study the evolution of chromosomes and genomes. Analyzing karyotype evolution in cruciferous plants highlights the origin of aberrant chromosomes in apomictic Boechera and further establishes the cruciferous plants as important model system for our understanding of plant chromosome and genome ...

Ecological model systems provide a conduit to understand the ecological impact of information gained from laboratory model species. Here, I review a 2011 meeting which focused on the systematic, ecological, evolutionary and developmental biology of the ecological model genus Boechera.
