Haploid-Phased Chromosomal Telomere-to-Telomere Genome Assembly of Medicinal Plant Uncaria rhynchophylla Dissects Genetic Controls on the Biosynthesis of Bioactive Alkaloids.

Natural indole alkaloids provide important medicinal resources and defences to environmental stresses. The Uncaria genus is a recorded traditional medicinal woody plant with high alkaloids. Genomic insights into alkaloid variation remain elusive.

Establishment of protoplasts transient expression system in Pinellia ternata (Thunb.) Breit.

Objective: In this study, we established an efficient and rapid transient expression system in the protoplasts of Pinellia ternata (Thunb.) Breit. (P.

Transcriptome revealing the dual regulatory mechanism of ethylene on the rhynchophylline and isorhynchophylline in Uncaria rhynchophylla.

Rhynchophylline (RIN) and isorhynchophylline (IRN) are extracted from Uncaria rhynchophylla, which are used to treat Alzheimer's disease. However, the massive accumulation of RIN and IRN in U. rhynchophylla requires exogenous stimulation.
