Characterization of the complete chloroplast genome sequence of Tsuga longibracteata W. C. Cheng (Pinaceae)

The complete chloroplast genome of Callicarpa macrophylla Vahl

Callicarpa macrophylla Vahl. belongs to the family Lamiaceae. Its root is a widely used Yao Medicine (YM) to treat internal and external bleeding at the Yao minority areas in southern China. Here, we provide the complete chloroplast genome of C. macrophylla which was collected from Laibin city in Guangxi, China. The total length of the chloroplast genome is 154,141 bp, including a large single-copy (LSC) region, a small single-copy (SSC) region, and a pair of inverted repeats (IRs) regions which are separated by the LSC and SSC, with lengths of 84,904 bp, 17,839 bp, and 25,699 bp, respectively. One hundred and thirty-one genes were identified, including 89 protein-coding genes, 34 tRNA genes, and eight rRNA genes. The overall GC content is 38%. Phylogenetic analysis revealed that C. macrophylla is closely related to C. integerrima var. chinensis.

Phylogenetic relationships and characterization of the complete chloroplast genome of Paphiopedilum ‘GZSLKY Youyou’, a hybrid of P. dianthum × P. barbigerum

Paphiopedilum ‘GZSLKY Youyou’. is a new cultivar of Paphiopedilum with highly ornamental and horticultural value developed by crossing female parent Paphiopedilum dianthum T. Tang & F. T. Wang 1940 and male parent Paphiopedilum barbigerum T. Tang & F. T. Wang 1940. In this study, the complete chloroplast genome of the cultivar has been reconstructed from the Illumina sequencing data. The circular genome was 160,503 bp in size, containing a large single-copy region (91,582 bp), a small single-copy region (3,215 bp) and a pair of IR regions (each one 32,853 bp). The overall GC contents of the chloroplast genome was 36.20%. The chloroplast genome contained 122 genes, including 76 protein coding genes, 38 tRNA genes and 8 rRNA genes. A maximum likelihood (ML) phylogenetic tree showed that the cultivar ‘GZSLKY Youyou’ was clustered into the same clade with its parents and was closest related to P. dianthum, reflecting a maternal inheritance of chloroplasts. This complete chloroplast genome resource could be further used for genomic studies, phylogenetic analyses, and genetic engineering and breeding of the genus Paphiopedilum.
