Banana cultivars are a staple food for more than 400 million people worldwide. Panama disease annihilated the dominant export cultivar 'Gros Michel' in the 1950s and caused significant loses in Central and South American economies until its replacement with the Cavendish variety. History is repeating itself. A new race, TR4, has devastated Cavendish plantations in Asia and was firstly identified in America in Colombia in 2019. Farmers face an imminent risk and require resilient crops.The project will answer fundamental questions on the diversity of immunity NLR receptors in bananas and plantains (Musa genus), and the relation of this diversity with ploidy and genome composition and response to Panama disease, a devastating fungal vascular disease in bananas. The project will identify candidate genes to contribute to developing resistant varieties.

香蕉品种是全世界4亿多人的主食。巴拿马病在20世纪50年代消灭了占主导地位的出口品种'格罗斯米歇尔'，并在中美洲和南美洲经济中造成了重大损失，直到它被卡文迪什品种所取代。历史在重演。一个新的种族TR4摧毁了亚洲的卡文迪什种植园，并于2019年在哥伦比亚首次在美洲被发现。该项目将回答有关香蕉和大蕉（Musa属）中免疫NLR受体多样性的基本问题，以及这种多样性与倍性和基因组组成的关系，以及对巴拿马病的反应，巴拿马病是一种毁灭性的香蕉真菌脉管疾病。该项目将确定有助于开发抗性品种的候选基因。
