The complete chloroplast genome of Artocarpus gongshanensis (Moraceae)

The chloroplast genome of Artocarpus gongshanensis S. K. Wu ex C. Y. Wu & S. S. Chang 1989, a threatened species endemic to China, was sequenced for the first time using Illumina NovaSeq 6000. The complete chloroplast genome assembly reveals a quadripartite structure with a total length of 160,174 bp, consisting of a large single-copy (LSC) region (89,311 bp) and a small single-copy (SSC) region (19,489 bp), separated by two inverted repeat (IR) regions (25,687 bp each). Phylogenetic reconstruction based on chloroplast genome data strongly supports that A. gongshanensis forms a sister clade with A. hypargyreus. Comparative genomic analyses demonstrate that the structural organization of A. gongshanensis chloroplast genome is conserved with other Artocarpus species. This newly characterized chloroplast genome provides critical molecular data for resolving taxonomic uncertainties within the genus and establishing evidence-based conservation measures for this threatened plant.
