Effects of Plant Stress on Facultative Apomixis in Boechera (Brassicaceae)

Effects of Plant Stress on Facultative Apomixis in Boechera (Brassicaceae)

A new chromosome was born: comparative chromosome painting in Boechera.

Comparative 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 evolution.

Boechera Species Exhibit Species-Specific Responses to Combined Heat and High Light Stress

As sessile organisms, plants must be able to complete their life cycle in place and therefore tolerance to abiotic stress has had a major role in shaping biogeographical patterns. However, much of what we know about plant tolerance to abiotic stresses is based on studies of just a few plant species, most notably the model species Arabidopsis thaliana. In this study we examine natural variation ...

Identification of Genes with Evidence of Expression only in Boechera or Arabidopsis For selection of genes with evidence of expression in the Arabidopsis MMC but not in the Boechera

The conserved chimeric transcript UPGRADE2 is associated with unreduced pollen formation and is exclusively found in apomictic Boechera species.

In apomictic Boechera spp., meiotic diplospory leads to the circumvention of meiosis and the suppression of recombination to produce unreduced male and female gametes (i.e. apomeiosis). Here, we have established an early flower developmental staging system and have performed microarray-based comparative gene expression analyses of the pollen mother cell stage in seven diploid sexual and seven d...
