The Boechera Genus as a Resource for Apomixis Research [PDF]

open access: yesFrontiers in Plant Science, 2019
The genera Boechera (A. Löve et D. Löve) and Arabidopsis, the latter containing the model plant Arabidopsis thaliana, belong to the same clade within the Brassicaceae family.

Seed size, endosperm and germination variation in sexual and apomictic Boechera [PDF]

open access: yesFrontiers in Plant Science, 2022
Asexual reproduction results in offspring that are genetically identical to the mother. Among apomictic plants (reproducing asexually through seeds) many require paternal genetic contribution for proper endosperm development (pseudogamous endosperm).

Sex- versus apomixis-specific polymorphisms in the 5′UTR of APOLLO from Boechera shift gene expression from somatic to reproductive tissues in Arabidopsis [PDF]

open access: yesFrontiers in Plant Science
IntroductionAmong candidate genes underlying the control components of apomixis, APOLLO is known for its strong linkage to apomeiosis in the genus Boechera.

Boechera or not? Genomic insights and taxonomic reassessment of the misclassified Asian species B. calcarea (Brassicaceae) [PDF]

open access: yesPlant Diversity
The genus Boechera (Brassicaceae) serves as a model system for studying apomictic reproduction and ecological adaptations, with most species occurring in North America.

Phenotypic plasticity and genetic diversity shed light on endemism of rare Boechera perstellata and its potential vulnerability to climate warming [PDF]

open access: yesEcology and Evolution, 2023
The rapid pace of contemporary environmental change puts many species at risk, especially rare species constrained by limited capacity to adapt or migrate due to low genetic diversity and/or fitness.

Genome structure and molecular phylogeny of the only Eurasian Boechera species, Boechera falcata (Brassicaceae). [PDF]

open access: yesG3 (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.

Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera [PDF]

open access: yesFrontiers in Plant Science, 2022
Asexual reproduction through seeds in plants (i.e., apomixis) is a heritable trait, and apomixis- linked loci have been identified in multiple species. However, direct identification of genomic elements is typically hindered as apomixis-linked loci and ...

Phylogenetic and Expression Analysis of CENH3 and APOLLO Genes in Sexual and Apomictic Boechera Species [PDF]

open access: yesPlants, 2022
Apomictic plants (reproducing via asexual seeds), unlike sexual individuals, avoid meiosis and egg cell fertilization. Consequently, apomixis is very important for fixing maternal genotypes in the next plant generations. Despite the progress in the study

Globally Relaxed Selection and Local Adaptation in Boechera stricta. [PDF]

open access: yesGenome Biol Evol, 2022
AbstractThe strength of selection varies among populations and across the genome, but the determinants of efficacy of selection remain unclear. In this study, we used whole-genome sequencing data from 467 Boechera stricta accessions to quantify the strength of selection and characterize the pattern of local adaptation. We found low genetic diversity on

Admixture, evolution, and variation in reproductive isolation in the Boechera puberula clade [PDF]

open access: yesBMC 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.
