However strong evidence that this supernumerary is an isochromosome was given by some additional mitotic and meiotic studies, which also indicated that its heterochromatic nature is related with the amplification and dispersion of highly repetitive sequences (Mestriner et al.
Mutations in SPECIFIC UBIQUITIN PROTEASE 32/UBIQUITIN-SPECIFIC PROTEASE 26 (SUP32/UBP26), an Arabidopsis deubiquitinating enzyme, result in decreased histone H3K9me2 levels, suppressed DNA methylation and release heterochromatic silencing.
