Some examples of TE insertion impact on genes. a) The FWA locus is repressed in vegetative tissues and the parentally-derived allele through an epigenetic mechanism induced by an old SINE insertion. Ectopic expression of the locus in a demethylated context causes a late-flowering phenotype. b) The FLC locus has a lower expression in the Ler accession caused by a Mutator-like insertion that affects the mRNA structure. c) The BONSAI locus is repressed by the loss of methylation of a LINE element inserted downstream. The TE is transcriptionally reactivated and produces small RNAs that repress the APC13-like gene to provoke a Bonsai phenotype
