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.
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 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.

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.
Arabidopsis deploys the core signalling module that perceives distinct stress signals, such as DNA damage and heat stresses, and represses G2/M-specific genes, thereby causing cell cycle arrest.
Hybridization barriers in Arabidopsis thaliana can be established by paternally expressed imprinted genes (PEGs) that affect cellularization of the endosperm during seed development.

The Arabidopsis N6-methyladenosine (m6A)-binding protein ECT2 binds to m6A in the canonical RR[m6A]CH motif, not a plant-specific motif as previously thought, and its intrinsically disordered region contributes to mRNA binding via contacts with U-rich motifs.
