Hybridization barriers in Arabidopsis thaliana can be established by paternally expressed imprinted genes (PEGs) that affect cellularization of the endosperm during seed development.
Population genomics in Arabidopsis thaliana uncovers an extensive repertoire of active transposable element families at the species level and reveals their importance as a source of rare alleles with large effects.
Genetic and biochemical analyses demonstrate that cell-surface lectin receptors can potentially function as extracellular NAD+-binding receptors and provide direct evidence for extracellular NAD+ being a bona fide endogenous signaling molecule in plants.
A comprehensive and genome-wide description of the genomic make-up and frequency of meiotic recombination in Arabidopsis thaliana reveals regional preferences, including nucleosome-free regions, and two associated recombination motifs.
A basidiomycete yeast closely related to fungal smuts is an antagonistic microbe in the Arabidopsis leaf phyllosphere that inhibits infection by Albugo laibachii via a GH25 hydrolase with lysozyme activity.
In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.
Sequencing mRNA directly with nanopores can reveal the authentic combinations of multiple mRNA processing events in full-length mRNA molecules in addition to identifying base modifications.
Natural variation for an adaptively important life history trait is largely due to variation at a single, major-effect locus with multiple alleles, demonstrating that not all complex traits are massively polygenic.
