Huang, Yuying published the artcileComprehensive analysis of complete chloroplast genome and phylogenetic aspects of ten Ficus species, Name: (S)-2-Amino-4-(methylthio)butanoic acid, the publication is BMC Plant Biology (2022), 22(1), 253, database is CAplus and MEDLINE.
The large genus Ficus comprises approx. 800 species, most of which possess high ornamental and ecol. values. However, its evolutionary history remains largely unknown. Plastome (chloroplast genome) anal. had become an essential tool for species identification and for unveiling evolutionary relationships between species, genus and other rank groups. In this work we present the plastomes of ten Ficus species. The complete chloroplast (CP) genomes of eleven Ficus specimens belonging to ten species were determined and analyzed. The full length of the Ficus plastome was nearly 160 kbp with a similar overall GC content, ranging from 35.88 to 36.02%. A total of 114 unique genes, distributed in 80 protein-coding genes, 30 tRNAs, and 4 rRNAs, were annotated in each of the Ficus CP genome. In addition, these CP genomes showed variation in their inverted repeat regions (IR). Tandem repeats and mononucleotide simple sequence repeat (SSR) are widely distributed across the Ficus CP genome. Comparative genome anal. showed low sequence variability. In addition, eight variable regions to be used as potential mol. markers were proposed for future Ficus species identification. According to the phylogenetic anal., these ten Ficus species were clustered together and further divided into three clades based on different subgenera. Simultaneously, it also showed the relatedness between Ficus and Morus. The chloroplast genome structure of 10 Ficus species was similar to that of other angiosperms, with a typical four-part structure. Chloroplast genome sizes vary slightly due to expansion and contraction of the IR region. And the variation of noncoding regions of the chloroplast genome is larger than that of coding regions. Phylogenetic anal. showed that these eleven sampled CP genomes were divided into three clades, clustered with species from subgenus Urostigma, Sycomorus, and Ficus, resp. These results support the Berg classification system, in which the subgenus Ficus was further decomposed into the subgenus Sycomorus. In general, the sequencing and anal. of Ficus plastomes, especially the ones of species with no or limited sequences available yet, contribute to the study of genetic diversity and species evolution of Ficus, while providing useful information for taxonomic and phylogenetic studies of Ficus.
