Absence of functional CAF-1 results in deficiencies in H3.3 levels at transcribed loci in Arabidopsis

A new study published in *Plant Physiology* reveals that the absence of functional Chromatin Assembly Factor 1 (CAF-1) leads to reduced levels of histone H3.3 at actively transcribed regions in *Arabidopsis*. This finding provides crucial insights into the mechanisms of chromatin assembly and gene expression regulation in plants.
