Musa itinerans, known also as Yunnan banana, is a close relative to both banana progenitors with wide distribution across subtropical China. It is native to south-east Asia and can be found in moist ravines to mountainous areas. In China, it is usually found in secondary tropical rainforests. It grows fast and can produce long rhizome with sucker emerging more than 2 meters from the mother plant, explaining its name origin.
Interestingly, It was shown as one of the most Foc-TR4 resistant and cold tolerant species in the Musa genus, providing valuable resource for the disease resistance and hardiness improvement in banana breeding.
The genome sequencing of this species is the result of the collaboration between SCBG CAS, Bioversity International and BGI. The study was financially supported by National Natural Science Foundation of China (No. 31261140366)
