Characterization of the complete plastid genome and 45S nrDNA sequences of Murdannia medica (Lour.) D.Y. Hong (Commelinaceae) and its phylogenetic analysis

Abstract

Abstract Murdannia medica is a Vietnamese traditional medicinal herb. Here, we report DNA super‑barcodes comprising the complete plastid genome (plastome, 177,455 bp) and 45S nuclear ribosomal DNA (45S nrDNA, 5,741 bp) of M. medica. The plastome has a large single‑copy (LSC, 100,132 bp), a small single‑copy (SSC, 21,125 bp), and a pair of inverted repeats (IRs) of 28,099 bp each. It contains 115 annotated genes and has an overall A/T content of 68.2%. Plastome‑based phylogenetic analyses show that M. medica sister with M. edulis. These new genomic resources provide a valuable foundation for future cultivation, conservation, and systematic investigations of M. medica.
