Table I. LincRNA derepression in the emf2b mutant shows bias toward those overlapping H3K27me3-enriched islands.

The H3K27me3 peak islands were assessed for overlap (No, Yes) with the location of lincRNAs derepressed in emf2b panicles (−1) versus lincRNAs not differentially expressed (0). Fisher’s exact test gave a P = 2.959e-10 that this would occur by chance alone.
