The complete chloroplast genome of Cupressus jiangeensis (cupressaceae), a critically endangered conifer species in China

摘要

Cupressus jiangeensis is a critically endangered conifer listed in the IUCN Red List of Threatened Species. Illumina pair-end reads of this species was used to character the whole chloroplast (cp) genome sequence. The circular genome with 128,286bp in length contains two duplicated genes (trnL and trnQ) and 115 single copy genes, including 82 protein-coding genes, 31 tRNA and four ribosomal RNA genes. Eight genes (atpF, ndhA, ndhB, rpoC1, petD, petB, rpl16 and rpl2) have a single intron, while two genes (rps12 and ycf3) have two introns. There are no inverted repeat sequences in this genome. The GC content of this cp genome is 34.68%. Phylogenomic analysis strongly supported the close relationship of C. jiangeensis and C. chengiana.
