Sugarcane 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.
We 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.
Sugarcane (Saccharum hybrids) is a highly productive C4 crop prevalent in tropical and subtropical areas. However, its photosynthetic efficiency is influenced by environmental factors such as light, moisture and temperature. Understanding these interactions is critical for optimizing yields and addressing climate-related challenges.

Drought tolerance is a desirable breeding characteristic for Colombian sugarcane cultivars, supporting the sustainable development goals of the country's agriculture.
The South African Sugarcane Research Institute is developing genetically modified (GM) sugarcane with enhanced resistance to Eldana saccharina by introducing Cry1Ab and Cry2Ab genes. Two genotypes, T10K and TN71, were selected as suitable candidates for transformation, representing South African sugarcane industry's rainfed and irrigated regions, respectively
Climate 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 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.
In 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.
Comparative mapping in sugarcane has had limited application due to initially markers such as AFLPs being used to generate maps for the large genome with no sequence information attached.
