Special Issue Information

Dear Colleagues,

Sugarcane (Saccharum spp.) is an important industrial C4 crop, accounting for 80% of sugar worldwide. Various biotic and abiotic stressors are major factors that can impede sugarcane’s entire growth and development period. Recently, numerous modern breeding and biotechnological approaches have been used to improve sugarcane’s agronomic attributes under stressful conditions. However, more investigations are required to explore detailed features regulating the balance between growth and defense responses in sugarcane. Creating climate-resilient cultivars is a smart strategy to enhance resilience and assist crop improvement in modern agriculture. Therefore, this Special Issue will highlight recent advances in the utilization of classical genetics, molecular breeding, and modern biotechnological approaches to increase sugarcane resilience and productivity in the context of sustainable agriculture. The aim and scope of this Special Issue include (but are not limited to) classical and molecular breeding, genomics selection, genome editing, double haploids, multi-omics, and smart agriculture, which contribute to the development of more resilient and productive sugarcane germplasm and varieties.

Sugarcane rust diseases are caused by Puccinia melanocephala (brown rust) and Puccinia kuehnii (orange rust), and significantly threaten the sustainable and stable development of the global sugarcane industry. Erianthus arundinaceus within the Saccharum complex is a potential germplasm resource for sugarcane breeding and is characterized by its tolerance of infertile land, drought, and diseases. However, the research on resistance to rust in E. arundinaceus clones and their offspring (F1 and backcross with modern sugarcane varieties) is limited. In this study, a total of 201 leaf samples from Saccharum spp. hybrids with rust symptoms were collected and screened for disease occurrence. PCR detection revealed that 17.9% and 34.8% of the samples were infected by P. melanocephala and P. kuehnii, respectively. Additionally, 12.9% of the samples were infected by both pathogens. A total of 88 clones of E. arundinaceus offspring and the parents plus 3 additional E. arundinaceus were selected for the identification of brown rust resistance by an artificial inoculation method. Among them, 61 clones displayed high resistance to brown rust. Molecular detection showed that 13 offspring of E. arundinaceus and 6 backcross parents of the “ROC” series exhibited the major resistance gene (Bru1) for brown rust. Unexpectedly, the Bru1 gene was absent in 42 clones that were resistant to brown rust, suggesting that other resistance genes for brown rust likely exist in E. arundinaceus and their offspring. Our results offer some significant genetic resources for developing sugarcane cultivars with resistance against rust. Full article
