B chromosomes (Bs) are supernumerary entities found in many plant species, with some exhibiting tissue-specific elimination. In Sorghum purpureosericeum, extensive level of the B chromosome elimination occurs during embryogenesis. It progresses quickly and affects most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems. Dynamic of the process and rarity of the transcripts associated with elimination make its capturing challenging…
