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.

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.

Ecological genetics of range size variation in Boechera spp. (Brassicaceae) [PDF]
Ecology and Evolution, 2015 AbstractMany taxonomic groups contain both rare and widespread species, which indicates that range size can evolve quickly. Many studies have compared molecular genetic diversity, plasticity, or phenotypic traits between rare and widespread species; however, a suite of genetic attributes that unites rare species remains elusive.

Applications in Plant Sciences, 2020 Premise The ability to sequence genome‐scale data from herbarium specimens would allow for the economical development of data sets with broad taxonomic and geographic sampling that would otherwise not be possible. Here, we evaluate the utility of a basic

Frontiers in Plant Science, 2016 Molecular dissection of apomixis - an asexual reproductive mode - is anticipated to solve the enigma of loss of meiotic sex, and to help fixing elite agronomic traits.

Are genetic variation and demographic performance linked?
Evolutionary Applications, 2022 Quantifying relationships between genetic variation and population viability is important from both basic biological and applied conservation perspectives, yet few populations have been monitored with both long‐term demographic and population genetics ...

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.

mSystems, 2023 Plant-associated microbial assemblages are known to shift at time scales aligned with plant phenology, as influenced by the changes in plant-derived nutrient concentrations and abiotic conditions observed over a growing season. But these same factors can

Evolutionary Applications, Volume 19, Issue 7, July 2026.ABSTRACT Anthropogenic climate change is rapidly disrupting populations and ecosystems, challenging conservationists to identify effective interventions. Assisted gene flow (AGF), the human‐assisted movement of species within their historic range to increase the population health of climate‐threatened species, offers a promising but controversial ...

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)
