Abstract Self-incompatibility in flowering plants is a common mechanism that prevents self-fertilization and promotes outcrossing. In Brassicaceae, there high genetic diversity at the locus controlling self-incompatibility, dozens of distinct alleles are organized complex dominance hierarchy: gene self-incompatibility specificity pollen shows monoallelic expression heterozygote individuals. This achieved through action sRNA precursors resemble miRNAs, although underlying molecular mechanisms...
Abstract Loss of DNA methylation over transposable elements (TEs) can affect neighboring genes and be epigenetically inherited in plants, yet the determinants significance this additional system inheritance are unknown. Here, we demonstrate at thousands TE loci across Arabidopsis thaliana genome, that experimentally-induced hypomethylation transmitted transgenerationally reveal role small RNAs derived from related copies counteracting transmission. Using data >700 strains collected...
