The plastid genome of a tropical tree Alseodaphne petiolaris (Lauraceae)

Abstract

Abstract Alseodaphne petiolaris Hook.f. is a valuable timber tree of the genus Alseodaphne Nees in the family Lauraceae. To better determine its phylogenetic location with respect to the other Alseodaphne species, the complete plastid genome of A. petiolaris was sequenced. The whole plastome is 152,986\u2009bp in length, consisting of a pair of inverted repeat (IR) regions of 20,108\u2009bp, one large single copy (LSC) region of 93,863\u2009bp, and one small single copy (SSC) region of 18,907\u2009bp. The overall GC content of the whole plastome is 39.1%. Further, maximum-likelihood phylogenetic analyse was conducted using 15 complete plastomes of the Lauraceae, which support the close relationship between A. petiolaris and the species of Machilus and Phoebe.
