Genome assembly This dataset contains the haplotype-resolved genome assembly and annotation of Polygonatum cyrtonema (Huangjing), a traditional Chinese medicinal and edible plant. The assembly comprises two phased haplotypes, totaling approximately 14.38 Gb across 22 pseudomolecules. The dataset includes the following files:<ul><li>Genome sequence (FASTA)</li><li>Gene annotation files (GFF3)</li><li>Coding sequences (CDS)</li><li>Protein sequences</li></ul>This genomic resource provides insights into the evolutionary mechanisms underlying the metabolic shift from starch to agavin-type fructan accumulation in P. cyrtonema rhizomes, driven by LTR retrotransposon expansion and neofunctionalization of a 6-SFT enzyme. The data also support population genomic analyses of 261 accessions, revealing genetic structure and trait-associated loci. This work establishes a foundation for understanding carbon allocation strategies in shade-adapted perennial plants and for breeding functional staple foods. 2026-10-02T16:11:08Z Dataset Dataset 10.6084/m9.figshare.33182618.v1 https://figshare.com/articles/dataset/Genome_assembly_and_annotation_of_i_Polygonatum_cyrtonema_i_Hua/33182618 CC BY 4.0
