Abstract:
The complete chloroplast genome of Amorphophallus josefbogneri Hett 2006 was sequenced, assembled, and annotated. The genome is 172,957 bp in length and exhibits a typical circular quadripartite structure with LSC 94,009 bp, SSC 14,946 bp, and two IRs of 32,001 bp each. The overall GC content is 34.96%. A total of 128 genes were annotated, including 83 protein-coding genes, 8 rRNA genes, and 37 tRNA genes, of which 110 are single-copy genes. Phylogenetic analysis places A. josefbogneri in a clade A. muelleri, A. kiusianus, A. yunnanensis, A. coaetaneus, and A. tonkinensis. This chloroplast genome provides a resource for developing molecular markers for species identification and phylogenetic studies within Amorphophallus.
