Chen Heming, an associate researcher at the Agricultural Biotechnology Research Center of Academia Sinica, has shifted her focus to combating banana yellow leaf disease, a significant threat to banana crops in Taiwan and globally, caused by the fungus Fusarium oxysporum. Through genetic sequence data analysis, her team has identified molecular markers for disease-resistant banana varieties, including the development of new varieties like the Baodao banana and Taiwan banana No. 5 and No. 7, with No. 5 already commercialized. The research employs innovative methods such as restriction enzymes and Sanger sequencing to pinpoint DNA sequences unique to these resistant varieties, aiding in the protection of plant variety rights and ensuring the preservation of Taiwan's banana industry against the disease. This approach not only helps in distinguishing these varieties from others but also plays a crucial role in addressing crop disease challenges and protecting agricultural innovations.
