Analysis of epigenetic recombinant inbred lines of Arabidopsis identified four hypomethylated DNA loci controlling quantitative disease resistance, which is associated with genome-wide priming of defence genes without affecting plant growth.
A genome-wide view of the gene regulatory network governed by WRKY33 has identified key targets that negatively regulate ABA biosynthesis to provide immunity against infection by a necrotrophic fungus.
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.
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.
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.
