The Chloroplast Genome of Lilium henrici: Genome Structure and Comparative Analysis
2018
Liliumhenrici Franchet, which belongs to the family
Liliaceae, is an endangered plant native to China. The wild populations of L. henrici have been largely reduced by habitat degradation or loss. In our study, we determined the whole
chloroplastgenome sequence for L. henrici and compared its structure with other
Lilium(including
Nomocharis) species. The
chloroplastgenome of L. henrici is a circular structure and 152,784 bp in length. The large single copy and small single copy is 82,429 bp and 17,533 bp in size, respectively, and the
inverted repeatsare 26,411 bp in size. The L. henrici
chloroplastgenome contains 116 different genes, including 78 protein coding genes, 30 tRNA genes, 4 rRNA genes, and 4
pseudogenes. There were 51 SSRs detected in the L. henrici
chloroplastgenome sequence. Genic comparison among L. henrici with other
Lilium(including
Nomocharis)
chloroplastgenomes shows that the sequence lengths and gene contents show little variation, the only differences being in three
pseudogenes. Phylogenetic analysis revealed that N. pardanthina was a sister species to L. henrici. Overall, this study, providing L. henrici genomic resources and the comparative analysis of
Lilium
chloroplastgenomes, will be beneficial for the evolutionary study and phylogenetic reconstruction of the genus
Lilium, molecular barcoding in population genetics.
