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

Pathways to polyploidy : indications of a female triploid bridge in the alpine species Ranunculus kuepferi (Ranunculaceae) [PDF]
, 2017 Polyploidy is one of the most important evolutionary processes in plants. In natural populations, polyploids usually emerge from unreduced gametes which either fuse with reduced ones, resulting in triploid offspring (triploid bridge), or with other ...

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.

Tackling Rapid Radiations With Targeted Sequencing [PDF]
, 2020 In phylogenetic studies across angiosperms, at various taxonomic levels, polytomies have persisted despite efforts to resolve them by increasing sampling of taxa and loci.

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.

Identification of ovule transcripts from the Apospory-Specific Genomic Region (ASGR)-carrier chromosome [PDF]
, 2011 Background Apomixis, asexual seed production in plants, holds great potential for agriculture as a means to fix hybrid vigor. Apospory is a form of apomixis where the embryo develops from an unreduced egg that is derived from a somatic nucellar cell, the

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.

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti-herbivore defenses, selection for qualitative toxins, and acceleration of plant-herbivore coevolution. [PDF]
Am J BotAbstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

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.
