A Near Telomere‐to‐Telomere Genome of Belamcanda chinensis Provides Insights Into Genome Evolution and the Biosynthesis of Characteristic Isoflavones

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Belamcanda chinensis is a non‐leguminous medicinal plant rich in bioactive isoflavones; however, the lack of a high‐quality reference genome has limited elucidation of its isoflavone biosynthetic and modification network. Here, we present the first near telomere‐to‐telomere genome assembly of B.
