Complete chloroplast genome of an endangered tree species Toona ciliata (Sapindales: Meliaceae)

摘要

The whole cp genome of T. ciliata was 159,502 bp in length, containing a pair of inverted repeat (26,961 bp for each), a large single copy (87,199 bp) and a small single copy (18,381 bp) regions. The cp genome encoded 138 genes, including 89 protein-coding genes, 40 tRNA genes, 8 rRNA genes and 1 pseudogene. The nucleotide composition was asymmetric (30.7% A, 19.3% C, 18.6% G and 31.4% T) with an overall GC content of 37.9%. The maximum likelihood phylogenetic analysis based on 21 complete cp genome sequences showed that T. ciliata closely related to Azadirachta indica.
