- Abstract
- Plastome sequences are crucial in plant studies due to their role in examining genomic evolution, understanding phylogenetic relationships, and developing molecular markers. Despite the collection of information about Korean figs, their genomic data remain underexplored. We utilize next-generation sequencing and PCR techniques to investigate genomic data and to develop and validate molecular markers. In this study, we characterize the complete plastomes of Korean figs: F. erecta, F. erecta var. sieboldii, F. sarmentosa var. nipponica, and F. sarmentosa var. thunbergii, which range in length from 160,276 to 160,603 bp. These genomes comprise 78 plastid protein-coding genes, 30 tRNA, and four rRNA, with the exception of one pseudogene, infA. We discovered that F. erecta and F. erecta var. sieboldii share identical plastome sequences. Phylogenomic analysis indicates the monophyly of Ficus, although the relationships among its subgenera remain unclear. We discovered that Ficus possesses 467 molecular diagnostic characters in its plastid protein-coding genes compared to other Moraceae groups, and F. erecta exhibits 33 molecular diagnostic characters. Single nucleotide polymorphisms in ndhD, petA, and rbcL were effectively used to develop molecular markers for distinguishing F. erecta from other figs. Additionally, we provided a straightforward PCR protocol for utilizing these newly developed molecular markers.
