Elevation of soybean seed oil content through selection for seed coat shininess
Blog, Plant Science Research Weekly, Research, Research BlogNat. Plants. Soybean is the world’s sixth most produced crop and is economically important as a source of protein and oil in animal and human food, as well as having industrial applications. Domestication of soybean has resulted in the absence of seed coat bloom, a powdery coating containing hazardous…
Evolution of transposon-encoded anti-silencing factors in Arabidopsis ($)
Blog, Plant Science Research Weekly, Research, Research BlogTransposable elements (TEs) are a major component of eukaryotic genomes. Their activity is silenced by epigenetic mechanisms such as chromatin modifications and DNA methylation in order to avoid deleterious effects on host genome stability. Nevertheless, how TEs overcome silencing by the host and propagate…
Anthers Crave Copper

Verification of Arabidopsis stock collections using SNPmatch, a tool for genotyping high-plexed samples
Blog, Plant Science Research Weekly, Research, Research BlogExperiments using large germplasm collections are prone to contamination. With dropping sequencing costs, it becomes easier to validate the genotype using minimal sequencing coverage. Pisupati and colleagues developed an open-source python pipeline, called SNPmatch, allowing identification of 930 Arabidopsis…
The plastid lipocalin LCNP is required for sustained photoprotective energy dissipation
Blog, Plant Science Research Weekly, Research, Research BlogPlants have several mechanisms to protect themselves from damage from excess light, including a set of reactions collectively described as non-photochemical quenching or NPQ. One of these is a sustained and slowly reversible form of NPQ, which the authors have named qH. How this sustained NPQ functions…
Trees are particularly robust to fixed somatic mutations
Blog, Plant Science Research Weekly, Research, Research BlogPlants lack a developmentally defined germline and gametes originate only late during plant development. This allows mutations acquired during the vegetative growth (somatic mutations) to be transmitted to the reproductive organs. The accumulation of mutations is relatively low in annual plants such…
Review. Artificial evolution: Creating genetic diversity in the lab ($)
Blog, Plant Science Research Weekly, Research, Research BlogHumans have been domesticating plants for 10,000 years, having an impact on the gene pools of multiple species chiefly through selective breeding approaches. Although plant domestication ensured food availability to early civilizations, plants were, and still are, mainly selected based on their morphology…
Pollen magnetofection for genetic modification with magnetic nanoparticles as gene carriers
Blog, Plant Science Research Weekly, Research, Research BlogThe ability to generate transgenic plants has revolutionised plant science research. However, many species and genotypes remain challenging and time-consuming to transform. Zhao et al. provide a novel and potentially ground-breaking method of transgene delivery. In the presence of a magnetic field,…
Development of gene expression system in egg cells and zygotes isolated from rice and maize
Blog, Plant Science Research Weekly, Research, Research BlogAssessing the function of genes active in zygotes and egg cells is difficult due to the inaccessibility of the target tissues. Koiso et al. isolated rice egg cells and maize zygotes using a method similar to that for extracting leaf protoplasts. They then optimized a PEG-Ca2+ transfection protocol…
