This study introduces RagTag, a toolset for automating assembly scaffolding and patching, and establishes chromosome-scale reference genomes for tomato genotypes M82 and Sweet-100. This provides convenience for functional genomics and genome editing in tomato.
Advancing crop genomics requires efficient genetic systems enabled by high-quality personalized genome assemblies. Here, we introduce RagTag, a toolset for automating assembly scaffolding and patching, and we establish chromosome-scale reference genomes for the widely used tomato genotype M82 along with Sweet-100, a new rapid-cycling genotype that we developed to accelerate functional genomics and genome editing in tomato. This work outlines strategies to rapidly expand genetic systems and genomic resources in other plant species.
