Here, we show, via single-nucleus RNA-seq of developing male gametophytes, that these repressors are critical for TE silencing in the pollen vegetative cell, a companion cell important for fertilization that undergoes chromatin decompaction. Reports of secondary structures in protein-depleted RNA fractions obtained from Arabidopsis (46, 47) led us to consider that some fragments in the Ribo-seq libraries are derived from regions of ribosome-associated transcripts that are RNase I-resistant due to dsRNA formation. These reads, together with the reads obtained from 3 published RNA-seq datasets 11, were assembled to reconstruct the Arabidopsis transcriptome. To fill this gap, we developed the C.
