A particular research focus of the project is genome size diversity, which varies more than 2,400-fold across plants.The largest genome so far reported for any organism is that of the Japanese canopy plant (Paris japonica; Melanthiaceae); its genome size is about 50 times larger than the human genome, and if its DNA was unravelled, would extend over 100 m. In contrast, the smallest plant genome size is found in a tiny carnivorous plant called Genlisea aurea. six Charophyceae, four Coleochaetophyceae and 49 Zygnematophyceae species), the new estimates in the database highlight considerable genome size variation.
