Tamarindus indica telomere-to-telomere genome reveals tartaric acid accumulation in fruit

• First telomere-to-telomere genome of Tamarindus indica. • Fruit sourness is likely driven by duplication of tartaric acid biosynthesis genes during lineage-specific WGD • Development of Tamarind Multi-Omics Database, a multi-omics database empowering breeding, evolutionary, and functional studies.
