Fig. 6From: siRNAs regulate DNA methylation and interfere with gene and lncRNA expression in the heterozygous polyploid switchgrassAssociation between 24-nt siRNA and DNA methylation in switchgrass. a Comparison of DNA methylation levels between siRNA uniquely mapping region and without that region in the whole genome-scale. ** represents highly significant difference (p < 0.01). b The Spearman analysis between DNA methylation, and siRNA expression surrounding genic region. rho > 0, means positive correlation; rho < 0, means negative correlation. Up, body, and down mean upstream, body, and downstream regions of genesBack to article page
