The complete chloroplast genome of (L.) Kuntze 1891 (), a hemiparasitic weed from Guangxi China.

(L.) Kuntze 1891 is a hemiparasitic plant native to Asia and Africa. It is invasive and causes yield losses in crops such as corn, rice and sorghum. Lack of chloroplast genomic data has limited research into its obligate parasitic lifestyle. In this study, the complete chloroplast genome of was sequenced and characterized. It is a quadripartite structure with a total length of 191,085 bp and a GC content of 37.86%. It has a large single copy region (LSC) of 51,406 bp, a small single copy region (SSC) of 273 bp, and two copies of the reverse repeat sequence (IRA and IRB) of 69,703 bp. A total of 122 protein-coding genes, 8 rRNA genes, and 44 tRNA genes were annotated in the chloroplast genome. There were a lot of gene deletions and pseudogenizations in this chloroplast genome. For example, A, D, E, H, I, and K were all pseudogenes because they were missing the 5' end start codon. B, C, and J had shorter gene lengths than their homologs, and F and G were missing genes. The phylogenetic tree reveals that all species form a clade, and a bootstrap value of 100 indicates that is closely related to and . The comprehensive chloroplast genomic resource of would assist researchers in comprehending hemiparasitic mechanisms, molecular markers, and evolutionary patterns of the genus .
