Association mapping and localization of molecular markers linked to resistance in sugarcane to brown rust
Last Updated: junio 19, 2025Sugarcane brown rust (Puccinia melanocephala) is a disease of major importance in many sugar producing regions of the world, causing significant yield losses and economic impacts. The most effective method for controlling this disease is the use of resistant commercial varieties.
Automation of artificial photoperiod in the north of Argentina
Last Updated: junio 19, 2025The Sugarcane Breeding Program at Chacra Experimental Agrícola Santa Rosa conducts crosses using artificial flower induction. To enhance this process, we developed a new automated photoperiod control system. This system utilizes microcontrollers that send ON/OFF signals to light fixtures in the photoperiod chambers while receiving real-time sensor data.
Biological corridors in sugarcane agro-landscapes: a strategy for sustainable pest management and biodiversity conservation
Last Updated: julio 6, 2025Biological corridors in agricultural landscapes connect patches of natural vegetation, linking areas with similar environmental characteristics. These corridors are crucial for preserving agroecosystem biodiversity benefiting beneficial insects.
Brix and stalk number associated with sugarcane productivity in different edaphoclimatic conditions in Brazil
Last Updated: junio 19, 2025Brix and stalk numbers associated with sugarcane productivity (Brix and number of stalks) were determined under different soil and climate conditions in Brazil using material from the early stages of the selection program of the Agronomic Institute of Campinas - IAC.
Chemical and plant-defense activator-based approaches to combat red rot caused by Colletotrichum falcatum in sugarcane
Last Updated: julio 6, 2025Red rot of sugarcane, caused by Colletotrichum falcatum, is the most destructive disease in many sugarcane-growing countries. Colletotrichum falcatum can reduce cane yield by up to 29% and cause sugar losses of up to 31%.
CRISPR/Cas9 mediated homology directed repair enables precise modification in sugarcane ALS gene
Last Updated: junio 19, 2025We investigated CRISPR/Cas9 homology-directed repair (HDR)-mediated introduction of the W574L mutation aimed at obtaining tolerance to acetolactate synthase (ALS) inhibiting herbicides. Specific sgRNAs were designed and inserted into Cas9-expressing gene editing vectors.
Cryo- and osmo-therapy to eliminate viruses from infected sugarcane
Last Updated: junio 19, 2025Virus elimination via cryo- or osmo-therapy has only been recently reported for sugarcane mosaic virus (SCMV). Cryotherapy offers the dual advantage of germplasm conservation and virus removal while osmotherapy (osmotic treatments without liquid nitrogen) is a suitable alternative treatment for those cultivars that do not recover well after cryo-treatment.
Current status of sugarcane smut in Tucumán, Argentina – evaluation of genetic resistance and fungicide applications as control strategies
Last Updated: junio 19, 2025Under a changing climate, sugarcane smut (Sporisorium scitamineum) has emerged as a significant threat in Tucumán, Argentina, since 2020. The distribution and intensity of smut across Tucumán sugarcane fields was determined and alternative control strategies for the disease analyzed.
Development of a real-time singleplex and multiplex PCR diagnostic assay for detecting sugarcane pathogens and optimization of nucleic acid extraction methods
Last Updated: junio 19, 2025Systemic sugarcane diseases were silently introduced to new areas due to the lack of appropriate and specific detection methods. Two bacterial diseases are the focus of the Sugarcane Disease Detection Lab (SDDL) in Louisiana – ratoon stunt disease (RSD), caused by Leifsonia xyli subsp. xyli, and leaf scald (LS), caused by Xanthomonas albilineans.
Development of internal transcribed spacer based molecular markers to identify Colletotrichum falcatum causing sugarcane red rot
Last Updated: junio 19, 2025Red rot, caused by Colletotrichum falcatum, is one of the most devastating fungal diseases of sugarcane occurring in Pakistan and is often referred to as “sugarcane cancer”. The pathogen, C. falcatum, shows significant variability, leading to the breakdown of resistance in many sugarcane varieties.
