Sugarcane smut disease caused by fungus Sporisorium scitamineum is a major disease and can cause significant yield losses worldwide. In Egypt, this disease is widespread in the commercial sugarcane variety G.T. 54-9. To study the molecular differentiation of S. scitamineum, Five S. scitamineum isolates were collected from five sugarcane production areas in Luxor Governorate (Luxor Grb, EL-Hbeal, EL-Karaia, EL-Mres and Ahaly EL-Mres) in season 2022 and were assessed based on the start codon-targeted (SCoT) marker technique. Four selected SCoT primers amplified 56 DNA fragments, of which 48 (85.71 %) were polymorphic. Polymorphic data ranged from 0.240 to 0.393, Which show that there is a degree of genetic diversity among these Egyptian fungus S. scitamineum isolates. Cluster analysis using UPGMA method was divided the S. scitamineum isolates into two main groups, I and II. Group II included only one isolate (isolate 2). Group I was divided into two sub-groups included Sub-G1 (isolates 1 & 3) and Sub-G2 (isolates 4 & 5). The results indicated that diversity of S. scitamineum was partly associated to its geographical origin. These results are useful in breeding programs to obtain smut-resistant sugarcane genotypes. Our results demonstrated that SCoT markers can be used to evaluate the genetic diversity of S. scitamineum.

Sugarcane smut caused by Sporisorium scitamineum represents the most destructive disease in the sugarcane industry, causing host hormone disruption and producing a black whip-like sorus in the apex of the stalk. In this study, the gibberellin metabolic pathway was found to respond to S. scitamineum infection, and the contents of bioactive gibberellins were significantly reduced in the leaves of diseased plants. The gibberellin receptor gene ScGID1 was identified and significantly downregulated. ScGID1 localized in both the nucleus and cytoplasm and had the highest expression level in the leaves. Eight proteins that interact with ScGID1 were screened out using a yeast two-hybrid assay. Novel DELLA proteins named ScGAI1a and ScGA20ox2, key enzymes in GA biosynthesis, were both found to interact with ScGID1 in a gibberellin-independent manner. Transcription factor trapping with a yeast one-hybrid system identified 50 proteins that interacted with the promoter of ScGID1, among which ScS1FA and ScPLATZ inhibited ScGID1 transcription, while ScGDSL promoted transcription. Overexpression of ScGID1 in transgenic Nicotiana benthamiana plants could increase plant height and promote flowering. These results not only contribute to improving our understanding of the metabolic regulatory network of sugarcane gibberellin but also expand our knowledge of the interaction between sugarcane and pathogens.

The MADS-box transcription factor (TF) gene family is pivotal in various aspects of plant biology, particularly in growth, development, and environmental adaptation. It comprises Type I and Type II categories, with the MIKC-type subgroups playing a crucial role in regulating genes essential for both the vegetative and reproductive stages of plant life. Notably, MADS-box proteins can influence processes such as flowering, fruit ripening, and stress tolerance. Here, we provide a comprehensive overview of the structural features, evolutionary lineage, multifaceted functions, and the role of MADS-box TFs in responding to biotic and abiotic stresses. We particularly emphasize their implications for crop enhancement, especially in light of recent advances in understanding the impact on sugarcane (Saccharum spp.), a vital tropical crop. By consolidating cutting-edge findings, we highlight potential avenues for expanding our knowledge base and enhancing the genetic traits of sugarcane through functional genomics and advanced breeding techniques. This review underscores the significance of MADS-box TFs in achieving improved yields and stress resilience in agricultural contexts, positioning them as promising targets for future research in crop science.
