Analysis of conserved microRNAs in floral tissues of sexual and apomictic
BMC Genomics, 2011 Background Apomixis or asexual seed formation represents a potentially important agronomic trait whose introduction into crop plants could be an effective way to fix and perpetuate a desirable genotype through successive seed generations.

Selection of reference genes for quantitative real-time PCR expression studies of microdissected reproductive tissues in apomictic and sexual
BMC Research Notes, 2011 Background Apomixis, a natural form of asexual seed production in plants, is considered to have great biotechnological potential for agriculture. It has been hypothesised that de-regulation of the sexual developmental pathway could trigger apomictic ...

The complete mitochondrial genome sequence of Boechera stricta [PDF]
Mitochondrial DNA. Part B. Resources, 2018 Boechera stricta (B. stricta) is a wild relative of Arabidopsis, occurring in mostly montane regions of western North America. In this article, we assembled the complete mitochondrial (mt) DNA sequence of B.

Admixture, evolution, and variation in reproductive isolation in the Boechera puberula clade [PDF]
BMC Evolutionary Biology, 2018 Background Hybridization is very common in plants, and the incorporation of new alleles into existing lineages (i.e. admixture) can blur species boundaries. However, admixture also has the potential to increase standing genetic variation.

Natural quantitative genetic variance in plant growth differs in response to ecologically relevant temperature heterogeneity [PDF]
Ecology and Evolution, 2016 Adaptation to large‐scale spatial heterogeneity in the environment accounts for a major proportion of genetic diversity within species. Theory predicts the erosion of adaptive genetic variation on a within‐population level, but considerable genetic ...

Frontiers in Plant Science, 2018 Differences in the timing of vegetative-to-reproductive phase transition have evolved independently and repeatedly in different plant species. Due to their specific biological functions and positions in pathways, some genes are important targets of ...

Recombination suppression in plant adaptation and speciation. [PDF]
New PhytolSummary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Genome structure and molecular phylogeny of the only Eurasian Boechera species, Boechera falcata (Brassicaceae). [PDF]
G3 (Bethesda)Abstract Boechera falcata (Turcz.) Al-Shehbaz, previously known as Arabis turczaninowii Ledeb., is a herbaceous perennial of the East Siberian, boreal-steppe ecotype. It is the sole species of the diverse genus Boechera found on the Eurasian continent, with all other species endemic to North America and Greenland.

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits. [PDF]
Ecol EvolThis systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Largest genome assembly in Brassicaceae: retrotransposon-driven genome expansion and karyotype evolution in Matthiola incana. [PDF]
Plant Biotechnol JSummary Matthiola incana, commonly known as stock and gillyflower, is a widely grown ornamental plant whose genome is significantly larger than that of other species in the mustard family. However, the evolutionary history behind such a large genome (~2 Gb) is still unknown.
