Researchers have successfully improved the haplotype-resolved genome sequence of the japonica rice cultivar Nipponbare, identifying and annotating over 3,000 new genes. This advancement, published in Tropical Plants, builds on the cultivar's historical significance as a reference in rice genomics and showcases the power of new sequencing technologies to enhance and refine genomic data. The comprehensive, phased genome assembly offers a solid foundation for further rice genetic research and breeding programs.
