Sugarcane (Saccharum hybrids) is the leading sugar crop, with stem elongation crucial for yield. We identified ScGID2, an F-box protein from cultivar ROC22, with broad expression in stems and leaves.
Lignin 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.
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.
