The complete chloroplast genome of Castanopsis sieboldii (Makino) Hatus (Fagaceae)

Castanopsis hystrix Hook. f. & Thomson ex A. DC. 1863 (Fagaceae) is an evergreen broad-leaved tree with high economic and ecological value. In this study, the complete chloroplast genome of C. hystrix was sequenced, assembled and annotated. The plastome (plastid genome) of C. hystrix was 160,624 bp in size, consisting of a pair of inverted repeats (IRs, 25,699 bp), a large-single-copy (LSC, 90,276 bp) region, and a small-single-copy (SSC, 18,950 bp). The overall GC content of C. hystrix was 36.8%. A total of 133 genes were annotated, including 88 protein-coding genes (PCG), 37 transfer RNA genes (tRNA), and eight ribosomal RNA genes (rRNA). A maximum likelihood analysis showed that the Castanopsis species form a monophyletic clade. C. hystrix is most closely related to C. tibetana with 100% bootstrap support value. The result enriches the genomic data for the genus Castanopsis , which will contribute to future studies in phylogenetics and evolution.

Utricularia tenuicaulis Miki 1935 is an aquatic carnivorous plant species found in East Asia including Korea and Japan. In this study, the chloroplast genome of U. tenuicaulis was successfully sequenced. The assembled genome (153,976 bp; GC ratio, 37.0%) contains four subregions, with the large single copy (LSC; 84,596 bp; 34.9%) and small single copy (SSC; 17,946 bp; 30.5%) regions separated by 25,718 bp of inverted repeat regions (42.7%), and includes 126 genes (81 protein-coding genes, 8 rRNAs, and 37 tRNAs). Phylogenetic analyses based on the whole-chloroplast genomes of 18 species, including 17 Lentibulariaceae species and one outgroup species, suggest a close relationship between U. tenuicaulis and Utricularia macrorhiza Leconte 1824. A comparison of genomic variation between U. tenuicaulis and U. macrorhiza confirmed the validity of the specific discrimination of U. tenuicaulis.

Lithocarpus litseifolius (Hance) Chun 1837 is an evergreen tree of Fagaceae, which can be used as sweet tea, natural sweetener, and precious medicinal material. The complete chloroplast genome of L. litseifolius was sequenced and its phylogenetic relationship was analyzed in this study. The chloroplast genome of L. litseifolius has a circular structure with a length of 161,322 bp, and it contains a pair of inverted repeat regions (IRs 25,897 bp), a large single copy (LSC 90,551 bp), and a small single copy (SSC 18,977 bp). There were 131 genes identified, including 37 tRNA, 8 rRNA, and 86 mRNA genes. Phylogenetic analysis of 23 species of Fagaceae indicated that Lithocarpus is monophyletic with strong bootstrap, and L. litseifolius is genetically closely related to Lithocarpus polystachyus.
