Sugarcane smut disease is caused by the biotrophic fungus Sporisorium scitamineum. The characterized development of a whip-like structure from primary meristems, where billions teliospores are produced. also causes tillering and low sucrose high fiber contents, reducing cane productivity. We investigated biological events contributing to symptoms in intermediate-resistant sugarcane genotype examining transcriptional profiles (RNAseq) shortly after inoculating plants immediately whip emission. overall picture progression suggests that premature reprogramming shoot meristem functions continues until emergence whip. guidance this altered pattern potentially primarily related auxin mobilization addition involvement other hormonal imbalances. consequences associated with emission modulation typical meristematic toward reproductive organ differentiation, requiring strong changes carbon partitioning energy production. These include overexpression genes coding for invertases trehalose-6P synthase, as well enzymes key metabolic pathways, such lignin biosynthesis. This first report describing following development, providing hypothetical model candidate further study progression.
