The role of linker H1 histones in plant defence has recently been investigated. Sheikh et al. found that Arabidopsis thaliana plants that were lacking all three H1 proteins showed increased disease resistance, but when primed, failed to induce enhanced resistance. Differences in epigenetic patterns could be the cause of defective priming.
Keywords: DNA methylation; chromatin; defence priming; linker histone; plant defences; plant immunity.
