Intertribal hybrid plants produced from crossing Arabidopsis thaliana with apomictic Boechera

open access: yesPlanta, 2012
Arabidopsis thaliana and Boechera belong to different tribes of the Brassicaceae and last shared a common ancestor 13-35 million years ago. A. thaliana reproduces sexually but some Boechera accessions reproduce by apomixis (asexual reproduction by seed).

Determination of the Developmental Origin of Seeds Containing Endosperm Using Flow Cytometric Analysis

open access: yesBio-Protocol, 2015
Seeds derived from a diploid, sexual plant typically contain a 2n embryo (n+n) and 3n endosperm, a ratio characteristic for most flowering plants. However, this ratio is altered in apomictic species, which reproduce asexually through seeds (Koltunow and ...

Functional Signatures of the Epiphytic Prokaryotic Microbiome of Agaves and Cacti. [PDF]

open access: yes, 2019
Microbial symbionts account for survival, development, fitness and evolution of eukaryotic hosts. These microorganisms together with their host form a biological unit known as holobiont. Recent studies have revealed that the holobiont of agaves and cacti

Spatially Varying Selection Amplifies Intrapopulation Differentiation Among Phenotypic Traits in the Rocky‐Shore Mussel, Mytilus californianus

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Strong ecological gradients along heterogeneous environments play an important role in shaping population differentiation across species ranges. We investigated the spatial variability of biological responses in the intertidal bivalve Mytilus californianus to highlight the costs and trade‐offs of local adaptation and phenotypic plasticity across ...

Genome-wide identification and expression analysis of SWI1 genes in Boechera species

open access: yesComputational Biology and Chemistry, 2016
As a mode of reproduction in plants, apomixis leads to the generation of clones via seeds. Apomictic plants form viable diploid female gametes without meiosis (apomeiosis) and produce embryos without fertilization (parthenogenesis). Apomeiosis, as a major component of apomixis, has recently been reported in some Arabidopsis thaliana mutants; dyad ...

Correction to: Ancient polymorphisms contribute to genome-wide variation by long-term balancing selection and divergent sorting in Boechera stricta

open access: yesGenome Biology, 2019
Following publication of the original article [1], the authors reported that the Availability of data and materials section required updating. The updated text reads as follows:

Costs of reproduction in flowering plants

open access: yesNew Phytologist, Volume 247, Issue 1, Page 55-70, July 2025.
Summary Costs of reproduction arise when investments into current reproduction reduce future reproductive fitness. Studies on reproductive costs use diverse approaches, including the analysis of gene expression, physiology, trade‐offs between reproduction and growth/survival, and the impact of reproductive investments on population growth.

Evolutionary constraint on low elevation range expansion: Defense‐abiotic stress‐tolerance trade‐off in crosses of the ecological model Boechera stricta

open access: yesEcology and Evolution, 2019
Most transplant experiments across species geographic range boundaries indicate that adaptation to stressful environments outside the range is often constrained. However, the mechanisms of these constraints remain poorly understood.

The Roles of Epigenetics in the Interplay Between Beneficial Rhizobacteria and Plants

open access: yesModern Agriculture, Volume 3, Issue 1, June 2025.
The activity of PGPR in soil enhances the availability of nutrients and hormones secreted by these PGPRs, while nutrients acquired from PGPR‐enriched soil induce epigenetic modifications in plants. These altered epigenetic marks subsequently regulate plant gene expression patterns, including those involved in metabolite synthesis (such as root exudates)
