“…Markers significantly associated with SCMV resistance were subjected to validation in two additional panels with sugarcane genotypes previously assessed for this trait. The first panel comprised 28 wild accessions, including representatives of S. officinarum , S. spontaneum , S. robustum , Saccharum barberi , and interspecific hybrids (da Silva et al ., 2015a), and the second panel comprised 64 Brazilian varieties and elite clones from the three main sugarcane breeding programs in Brazil (da Silva et al ., 2015b). These 92 genotypes (Table S2) were used for validation using MonsterPlex Technology (Floodlight Genomics, Knoxville, USA).…”

“…However, with respect to sugarcane, data on resistance to this virus are scarce. A few phenotypic studies have been performed in Brazil: specifically, researchers have evaluated the genotypic correlation of this disease incidence in sugarcane families (Xavier et al ., 2013) and screened diverse genotypes for resistance (da Silva et al ., 2015a, b). In addition, three marker– trait association studies have been carried out targeting SCMV resistance in this crop (Barnes et al ., 1997; Pinto et al ., 2013; Burbano et al ., 2022); however, most included very few genotypes (≤50), and all employed dominantly scored markers.…”

Sugarcane mosaic virus (SCMV) is the main etiological agent of sugarcane mosaic disease, which affects sugarcane, maize and other economically important grass species. Despite the extensive characterization of quantitative trait loci controlling resistance to SCMV in maize, the genetic basis of this trait is largely unexplored in sugarcane. Here, a genome-wide association study was performed and machine learning coupled to feature selection was used for the genomic prediction of resistance to SCMV in a diverse panel of sugarcane accessions. This ultimately led to the identification of nine single nucleotide polymorphisms (SNPs) explaining up to 29.9% of the phenotypic variance and a 73-SNP set that predicted resistance with high accuracy, precision, recall, and F1 scores. Both marker sets were validated in additional sugarcane genotypes, in which the SNPs explained up to 23.6% of the phenotypic variation and predicted resistance with a maximum accuracy of 69.1%. Synteny analyses showed that the gene responsible for the major SCMV resistance in maize is probably absent in sugarcane, explaining why such a major resistance source is thus far unknown in this crop. Lastly, using sugarcane RNA sequencing data, markers associated with the resistance to SCMV in sugarcane were annotated and a gene coexpression network was constructed to identify the predicted biological processes involved in SCMV resistance. This allowed the identification of candidate resistance genes and confirmed the involvement of stress responses, photosynthesis and regulation of transcription and translation in the resistance to this virus. These results provide a viable marker-assisted breeding approach for sugarcane and identify target genes for future molecular studies on resistance to SCMV.

“…The severity of mosaic disease in sugarcane fields is closely associated with sugarcane variety, infected setts, climatic conditions, and intermediate hosts. Among the six Saccharum species, S. officinarum are highly susceptible, S. sinense , S. spontaneum [ 67 ] and S. barber [ 68 ] are highly resistant or immune, S. robustum [ 67 , 68 ] are susceptible to mosaic. This disease was also found on S. edule [ 69 ], but the resistance to viruses is still uncertain.…”

“…The genetic base of modern sugarcane cultivars is narrow, with about 80% from S. officinarum , 10–15% from S. spontaneum , and 5–10% from recombinant chromosomes [ 142 ]. During the long evolutionary process, the Saccharum and its related genera have formed extremely rich and valuable germplasm resources [ 68 , 143 ], which contain large numbers of disease resistance genes [ 144 ]. In recent years, some Saccharum hybrid clones with high resistance to mosaic disease have been identified by natural infection or artificial inoculation, such as SP70-1143, IACSP95-2078 [ 145 ], SWSwm1 [ 146 ], YG34, YG55 [ 147 ], ROC16 [ 38 ], GT03-2309, and LC03-1137 [ 39 ].…”

Mosaic is one of the most important sugarcane diseases, caused by single or compound infection of Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV), and/or Sugarcane streak mosaic virus (SCSMV). The compound infection of mosaic has become increasingly serious in the last few years. The disease directly affects the photosynthesis and growth of sugarcane, leading to a significant decrease in cane yield and sucrose content, and thus serious economic losses. This review covers four aspects of sugarcane mosaic disease management: first, the current situation of sugarcane mosaic disease and its epidemic characteristics; second, the pathogenicity and genetic diversity of the three viruses; third, the identification methods of mosaic and its pathogen species; and fourth, the prevention and control measures for sugarcane mosaic disease and potential future research focus. The review is expected to provide scientific literature and guidance for the effective prevention and control of mosaic through resistance breeding in sugarcane.

In the last decades environmental concerns and sustainability have grown. In this context, the biorefinery concept arose. In Brazil, one of the leading agro-industrial crops is the production of sugarcane. The sugar industry is already a model of a biorefinery because of the possibility of producing ethanol, sugar and even electricity. However, plant biomass still has a great potential to produce new materials and chemicals. Some of the capabilities are: (i) the use of the sugars from the polysaccharide fraction aiming the ethanol production; (ii) the production of pulp and paper; (iii) production of nanomaterials, among others. This work aims to seek and apply technologies and processes to obtain different products from sugarcane. The first used is the separation of the rind and core fractions of sugarcane: in the rind there is a low amount of sugar storage cells and a higher proportion of structural fibers, and also wax from the epidermis; the core fraction concentrates the majority of the sucrose rich broth as consequence of the high quantity of parenchyma cells. In order to increase the concentration of saccharides a hydrothermal process was studied using the own juice of sugar cane to extract sugars from the hemicellulose fraction. It was observed that for the hydrothermal reaction in neutral medium in the temperature range studied (110 to 130 °C) of about 95% saccharides are conserved. However, in these reaction conditions the hemicellulose preservation is also kept in this range, so it was found that the use of an acid catalyst allow similar saccharides recovery and accelerate the hemicellulose removal. Using similar procedures to those of the pulp and paper industry two cellulosic materials with differentiated physical and mechanical characteristics were obtained from the rind and core fractions of sugarcane. Although most parenchyma content in the original core material, it was observed that this fraction showed promising results with properties similar to commercial papers. From these pulps, two different nanofibrillated cellulosic materials were obtained, being the rind material a ductile material and the core a rigid (higher Young's modulus) and brittle (lower elongation at break) one. It was also found that from these pulps cellulose II nanocrystals can be produced using a process of hydrolysis and solubilization with sulfuric acid followed by a reprecipitation process. The production of cellulose I nanocrystals through processes using subcritical water with or without CO2 were developed. These processes have the potential to replace the current nanocrystals production since only water is used (with or without CO2) to promote the hydrolysis, compared to the traditional method, which uses high concentrations of sulfuric acid, thus enabling economical saves and producing less amount of wastes.
