SNP variability in the sugarcane caffeic acid O-methyltransferase (COMT): a key gene for lignin biosynthesis
Last Updated: junio 19, 2025Lignin is a complex polymer that reduces biomass recalcitrance and limits the use of sugarcane (Saccharum hybrids) for second-generation ethanol production. Among the key genes involved in lignin biosynthesis pathway, caffeic acid O-methyltransferase (COMT) impacts on both lignin content and composition.
Stalk damage as an indicator of borer infestation and sucrose loss
Last Updated: julio 6, 2025A multi-stage field sampling method was developed to select sugarcane stalks, which were then longitudinally split to determine the percentage of stalks damaged by Diatraea spp. borers. Physical comparisons (height, thickness, and weight) were made between healthy and damaged stalks.
Status of red stripe disease in Tucumán, Argentina, in the last four years
Last Updated: junio 19, 2025Red stripe disease (RS) in sugarcane [Acidovorax avenae subsp. avenae (Aaa)] has gained importance in the last decade in Tucumán, the leading sugarcane-producing province in Argentina, but several aspects of this disease are still unknown.
Sugarcane disease risk assessment in two regions of Cuba
Last Updated: junio 19, 2025Climate change is expected to have an increasing influence on the diseases and insect pests that impact agriculture. The objective of this study was to identify the vulnerability of the sugarcane production systems in Mayabeque and Santiago de Cuba areas of Cuba, using indicators to assess the risk of disease outbreaks
Sugarcane lines expressing the sunflower transcription factor HAHB11 have improved tolerance to abiotic stresses
Last Updated: junio 19, 2025Climate change is impacting crop production worldwide, causing significant yield losses. Genetic transformation represents an essential biotechnological tool for mitigating abiotic stress in crops. In this study, we introduced the sunflower transcription factor Hahb11 gene into the elite sugarcane variety TUC 03-12 by the biolistic transformation method.
Sugarcane mild mosaic virus in commercial varieties and advanced lines in Florida
Last Updated: junio 19, 2025Several viral diseases affect sugarcane production worldwide. In 2022, a severely stunted principal commercial variety, CP 06-2400, growing in the crossing line at the USDA-ARS Sugarcane Field Station in Canal Point, Florida, was tested using high-throughput sequencing and found to be infected with Sugarcane mild mosaic virus (SCMMV).
Sustainable sugarcane: developing varieties resilient to pests and climate change through genetic transformation and genome editing
Last Updated: junio 19, 2025Sugarcane is a crucial crop in Colombia, serving as a key source of sugar, bioethanol, and cogeneration of electricity, and is a pillar of the agricultural economy. However, it faces significant threats from pests such as Diatraea sp. and water stress.
The biostimulant Howler® as a protectant against Diatraea saccharalis in sugarcane field trials
Last Updated: julio 6, 2025Diatraea saccharalis (Lepidoptera: Crambidae), the sugarcane borer, is the most important sugarcane pest in Tucumán, Argentina, due to stem damage and sugar loss. Although cultural, biological, and chemical control methods exist, their effectiveness in the region has been limited. ITANOA, CONICET-EEAOC developed and patented Howler® (Summit-Agro), a biological product for sustainable disease management containing subtilisin AsEs, an extracellular protease with plant defence-inducing activity produced by the fungus Sarocladium strictum SS71
The complex polyploid genome architecture of sugarcane: genome assembly and origin of cultivar R570
Last Updated: junio 17, 2025In 2024, we produced a polyploid genome assembly of the modern cultivar R570. This assembly was obtained using a combination of approaches and sequencing technologies and resulted in 67 assembled chromosomes. We found that many chromosome segments, representing ~50% of the genome, were nearly identical and thus collapsed in the assembly.
The crucial role of the EEAOC breeding program: varietal diversification in the sugarcane area of Tucumán, Argentina in the last 10 years
Last Updated: junio 19, 2025The Sugarcane Breeding Program of the Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC) is focused on the development of TUC varieties with high yield of cane and sucrose, early maturation, and resistance to the main diseases prevalent in Tucumán, Argentina.
