Meiocytes, Microspores, and Mature Pollen Grain Accumulate Overlapping Sets of siRNAs.
(A) TE-derived siRNA distribution in Arabidopsis meiocytes of the indicated genetic backgrounds (data from Huang et al., 2019). RPM, reads per million mapped reads; wt, wild type.
(B) TE-derived siRNA distribution in Arabidopsis pollen grains of the indicated genetic backgrounds.
(C) UpSet plot showing the overlap of TEs accumulating 21/22-nucleotide siRNAs or 24-nucleotide siRNAs in Arabidopsis microspores and meiocytes (data from Huang et al., 2019).
(D) UpSet plot showing the overlap of TEs accumulating 21/22-nucleotide siRNAs or 24-nucleotide siRNAs in Arabidopsis microspores and mature pollen grain (MPG; data from Martinez et al., 2018).
