Mutations in the SWEET15 Sugar Transporter Gene Affect Response of Citrus to Huanglongbing Disease and Citrus Canker

Molecular Plant Pathology, Volume 26, Issue 5, May 2025.
Assays of knockouts in several SWEET genes show that SWEET15 mutations reduce levels of Xanthomonas citri pv. citri and “Candidatus Liberibacter asiaticus” in infected citrus plants, suggesting that SWEET15 is a susceptibility gene. ABSTRACT Bacterial diseases like huanglongbing (HLB) and citrus canker severely impact citrus production. HLB, caused by “
