Abstract: Sugarcane (Saccharum officinarum) is avital cash crop and agro-industrial product, especially in India, which is one of the largest producers and consumers of sugar. However, its cultivation is severely affected by various diseases, with red rot—caused by the fungal pathogen Colletotrichum falcatum—being one of the most destructive. This disease, often referred to as the "cancer of sugarcane," leads to major losses in both yield and quality. The fungus is highly variable in nature, which frequently leads to the failure of resistant varieties due to the emergence of new, more virulent strains. Red rot has been reported for over a century in many sugarcane-growing countries including India, Java, Argentina, and the USA. Despite efforts like hybridization between cultivated sugarcane and wild species to breed resistant varieties, periodic outbreaks have occurred due to the widespread cultivation of a single variety and the breakdown of resistance over time. To understand the biology of C.falcatum and aid in disease management, this study focused on identifying and modeling potential drug target proteins from the pathogen. A protein sequences were retrieved from the UniProt database, and 3D structural models were developed using tools like Swiss Model and BLASTp. models were validated as significant using Ramachandran plot analysis. This dataset of protein structures could be a valuable resource for targeted drugdiscovery and development of antifungal treatments for managing red rot disease in sugarcane. Additionally, recent genomic and transcriptomic studies on C. falcatum have identified potential effector genes and pathogenicity hotspots, which can support future efforts in genetic improvement and integrated disease management strategies. Other approaches including bioagents, chemical treatments, and mechanized sett treatments are also showing promising results in controlling the disease in the field.
