Abstract

Abstract: Parasassafras confertiflorum (Meisn.) D.G. Long is the single tree species of the genus Parasassafras D.G. Long in the family Lauraceae. To better determine its phylogenetic location with respect to the related Lauraceae species, the complete chloroplast genome of P. confertiflorum was sequenced. The whole plastome is 152, 555 bp in length, consisting of a pair of inverted repeat (IR) regions of 20, 079 bp, one large single copy (LSC) region of 93, 604 bp, and one small single copy (SSC) region of 18, 793 bp. The genome contains 127 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, and 36 transfer RNA genes. The overall GC content of the whole plastome is 39.1%. Further, maximum likelihoodphylogenetic analyses were conducted using 34 complete plastomes of the Lauraceae, which support close relationships between P. confertiflorum and Actinodaphne trichocarpa, Lindera benzoin, L. latifolia, L. metcalfiana, L. robusta, and Neolitsea sericea rather than Laurus nobilis or Sinosassafras flavinervium .
