Genetic discovery offers hope for global banana farming Scientists have pinpointed crucial genetic resistance to a fungal disease that threatens the global banana supply in a wild subspecies of the fruit. In a valuable step forward for banana breeding programs, Dr. Andrew Chen and Professor Elizabeth Aitken from the University of Queensland have identified the genomic region that controls resistance to Fusarium wilt Subtropical Race 4 (STR4). The study is published in the journal Horticulture Research. "Fusarium wilt—also known as Panama disease—is a destructive soil-borne disease which impacts farmed Cavendish bananas worldwide through its virulent Race 4 strains," Dr. Chen said. "Identifying and deploying natural resistance from wild bananas is a long-term and sustainable solution to this pathogen that wilts and kills the host plant leaving residue in the soil to infect future crops.
