Nuclear DNA ITS and ETS sequences of 71 representatives from nine genera and 11 sections of the core Laureae were combined with a matrix of morphological characters, analyzed using maximum parsimony with both equally and successively weighted characters, and analyzed for Bayesian inference, minimum evolution by neighbor joining, and maximum likelihood inference for molecular data alone. The large genera Actinodaphne Nees, Lindera Thunb., and Litsea Lam.

Phylogenetic relationships within the ‘core’ Laureae ( Litsea complex, Lauraceae) inferred from sequences of the chloroplast gene mat K and nuclear ribosomal DNA ITS regions2004 •
A phylogenetic analysis of the ‘core’ Laureae (Litsea complex) was conducted using the chloroplast gene matK and nuclear ribosomal DNA ITS sequences to investigate generic relationships and boundaries within the complex. Despite low genetic divergence for matK, rooting of the tree with Sassafras resulted in Iteadaphne as the basal member of the complex and five resolved clades: a Neolitsea clade and then Laurus, Parasassafras, Litsea and Lindera clades in a large polytomy with unresolved Lindera sections plus Umbellularia. A combined analysis of the data (identical to the ITS results) provided a more resolved phylogeny of the Laureae, with four major lineages: the Laurus, Litsea, Lindera and Actinodaphne II clades. These clades also appear to reflect the importance of inflorescence structure and ontogeny within the Laureae, as well as data from cuticular micromorphology, but there was no support for traditional generic characters such as 2- versus 4- celled anthers. As a result, genera such as Actinodaphne, Litsea, Neolitsea and Lindera were polyphyletic in all analyses. Parasassafras was related to Sinosassafras by the matK data, but distant from it in the ITS and combined analyses.

Abstract ITS and ETS-based sequence analyses of 29 Neolitsea, six Actinodaphne and five outgroupcore'Laureae taxa show that Neolitsea is monophyletic with two large subclades, whereas most of the sampled Actinodaphne are paraphyletic below it.

Comparative Chloroplast Genomics of Litsea Lam. (Lauraceae) and Its Phylogenetic Implications2021 •
Litsea Lam. is an ecological and economic important genus of the "core Lauraceae" group in the Lauraceae. The few studies to date on the comparative chloroplast genomics and phylogenomics of Litsea have been conducted as part of other studies on the Lauraceae. Here, we sequenced the whole chloroplast genome sequence of Litsea auriculata, an endangered tree endemic to eastern China, and compared this with previously published chloroplast genome sequences of 11 other Litsea species. The chloroplast genomes of the 12 Litsea species ranged from 152,132 (L. szemaois) to 154,011 bp (L. garrettii) and exhibited a typical quadripartite structure with conserved genome arrangement and content, with length variations in the inverted repeat regions (IRs). No codon usage preferences were detected within the 30 codons used in the chloroplast genomes, indicating a conserved evolution model for the genus. Ten intergenic spacers (psbE-petL, trnH-psbA, petA-psbJ, ndhF-rpl32, ycf4-cemA, rpl32-trnL, ndhG-ndhI, psbC-trnS, trnE-trnT, and psbM-trnD) and five protein coding genes (ndhD, matK, ccsA, ycf1, and ndhF) were identified as divergence hotspot regions and DNA barcodes of Litsea species. In total, 876 chloroplast microsatellites were located within the 12 chloroplast genomes. Phylogenetic analyses conducted using the 51 additional complete chloroplast genomes of "core Lauraceae" species demonstrated that the 12 Litsea species grouped into four sub-clades within the Laurus-Neolitsea clade, and that Litsea is polyphyletic and closely related to the genera Lindera and Laurus. Our phylogeny strongly supported the monophyly of the following three clades (Laurus-Neolitsea, Cinnamomum-Ocotea, and Machilus-Persea) among the above investigated "core Lauraceae" species. Overall, our study highlighted the taxonomic utility of chloroplast genomes in Litsea, and the genetic markers identified here will facilitate future studies on the evolution, conservation, population genetics, and phylogeography of L. auriculata and other Litsea species.

Plastid phylogenomics improve phylogenetic resolution in the Lauraceae2019 •
The family Lauraceae is a major component of tropical and subtropical forests worldwide, and includes some commercially important timber trees and medicinal plants. However, phylogenetic relationships within Lauraceae have long been problematic due to low sequence divergence in commonly used markers, even between morphologically distinct taxa within the family. Here we present phylogenetic analyses of 43 newly generated Lauraceae plastomes together with 77 plastomes obtained from GenBank, representing 24 genera of Lauraceae and 17 related families of angiosperms, plus nine barcodes from 19 additional species in 18 genera of Lauraceae, in order to reconstruct highly supported relationships for the Lauraceae. Our phylogeny supports the relationships: sisterhood of the Lauraceae and a clade containing Hernandiaceae and Monimiaceae, with Atherospermataceae and Gomortegaceae being the next sister groups, followed by Calycanthaceae. Our results highlight a monophyletic Lauraceae, with nine well-supported clades as follows: The topology recovered here is consistent with the patterns of plastome structural evolution and morphological synapomorphies reported previously. More specifically, flower sex, living type, inflorescence type, ovary position, anther locus number, leaf arrangement, leaf venation, lateral vein number, tree height, and inflorescence location all represent morphological synapomorphies of different lineages. Our findings have taxonomic implications and two new tribes, Caryodaphnopsideae and Neocinnamomeae, are described, while the composition of four other tribes is updated. The phylogeny recovered here provides a robust phylogenetic framework through which to address the evolutionary history of the magnoliids, the third-largest group of Mesangiospermae.

An investigation of a questionable species of the genus Alseodaphne led to the discovery of a new genus Alseodaphnopsis H. W. Li & J. Li, gen. nov., separated from Alseodaphne Nees, and a new species Alseodaphnopsis ximengensis H. W. Li & J. Li, sp. nov., endemic to Yunnan province, China. This new species is characterized by having big, axillary, paniculate inflorescences, as well as large, subglobose fruits. Based on DNA sequence data from two gene regions (nuclear ribosomal ITS and LEAFY intron II), we investigate its phylogenetic position within the Persea group. Phylogenies using maximum parsimony (MP) and Bayesian inference (BI) support the recognition of Alseodaphnopsis as a distinct genus but do not resolve well its relationship within the Persea group. The new genus is circumscribed, eight new combinations for its species are made, and a description and illustration of the new species are provided.
