RANGE OF MULTIPLICATIONS. “Writ large, over the grand sweep of angiosperm history, we now understand that modern angiosperm genomes range in genomic complexity from those that have experienced few genomic multiplication events (e.g., Amborella, Allium, Olea, Theobroma) to others that reflect as many as 128 (Saccharum), 144 (Gossypium), and even 288 (Brassica) genomic multiples.”
