A chromosome-level genome assembly of Alpinia officinarum Hance sheds new light on its evolution and flavonoid biosynthesis. Alpinia officinarum

Alpinia officinarum Hance, a medicinal and edible plant in the Zingiberaceae family, has applications in pharmaceuticals, food, nutraceuticals, spices, cosmetics, and fruit and vegetable preservation. However, the molecular mechanisms governing the biosynthesis of flavonoids, the main bioactive compounds in A. officinarum, remain unclear. This study provided the first chromosome-grade genome assembly of A. officinarum and relevant information for future A. officinarum improvement and breeding efforts.
