摘要 The genetic information linearly scripted in chromosomes is wrapped in a ribonucleoprotein complex called chromatin. The adaptation of its compaction level and spatiotemporal organization refines gene expression in response to developmental and environmental cues. RNA polymerase III (RNAPIII) is responsible for the biogenesis of elementary non-coding RNAs. Their genes are subjected to high duplication and mutational rates, and invade nuclear genomes. Their insertion into different epigenomic environments raises the question of how chromatin packing affects their individual transcription. In this review, we provide a unique perspective to this issue in plants. In addition, we discuss how the genomic organization of RNAPIII-transcribed loci, combined with epigenetic differences, might participate to plant trait variations.
