Cereals play a major role in the world's food industry. Even though Sorghum itself is an important food crop, it's especially interesting since it's very closely related to maize and sugarcane. But as these two species had additional whole genome duplications their genomes are four times larger and are very hard to sequence due to the redundancy in the genome. Unlike previously sequenced plants Sorghum also has 'C4' photosynthesis; this is an adaptation of the standard 'C3'; photosynthesis, that assimilates carbon better at high temperatures.
