Plants in the genus Amorphophallus, many of which possess high konjac glucomannan content, are considered important cash crops Asian countries. Wild relatives cultivated Amorphophallus species valuable resources for genetic improvement these crops. To aid future research wild germplasm a single individual krausei Engler, Pflanzenr 1911 was collected from southwestern China, and its chloroplast genome sequenced using next-generation sequencing technologies. The assembled 172,418 bp length with GC content 35.23% (GenBank accession no. OR416863). A typical quadripartite structure found genome, comprised one large single-copy (LSC), small (SSC), two inverted repeats (IRs), lengths 91,983 bp, 15,591 32,422 respectively. total 132 genes were annotated including 86 protein-coding genes, 38 tRNAs, 8 rRNAs. maximum likelihood (ML) tree A. 17 other family Araceae suggested that all formed monophyletic clade. close relationship among konjac, albus, also revealed by phylogenetic tree. newly will support studies, particularly assessment diversity, resource conservation, phylogeographic research.
