Characterization of the complete chloroplast genome of Taxillus nigrans

Abstract

Taxillus nigrans (Hance) Danser (Loranthaceae) is a widely distributed mistletoe species in low mountains, hills, and river basins in subtropical areas of southwestern China. The whole chloroplast (cp) genome sequence of T. nigrans has been characterized using Illumina pair-end sequencing. The complete cp genome was 121,419 bp in length, containing a large single copy (LSC) region of 70,181 bp and a small single copy (SSC) region of 6100 bp, which were separated by a pair of 22,569 bp inverted repeat (IRs) regions. The genome contained 106 genes, including 66 protein-coding genes, 28 tRNA genes, 8 ribosomal RNA genes, and 4 pseudogenes. The most of gene species occur as a single copy, while 15 gene species occur in double copies. The overall GC content of T. nigrans cp genome is 37.4%, while the corresponding values of the LSC, SSC, and IR regions are 34.8, 26.3, and 42.95%, respectively. Phylogenetic analysis revealed that T. nigrans is closely related to T. sutchuenensis, with strong support values.
