Lindera is a genus (c. 100 spp.) of trees belonging to the “core Laureae” group in the family Lauraceae. It is often confused with Litsea, and the systematics of the genus is unclear. Here, total 10 complete plastomes from nine trinerved Lindera species and another species Lindera obtusiloba (sect. Palminerviae Meissn.) were sequenced. Nine highly variable regions, trnH-GUG/psbA, psbM/trnD-GUC, petA/psbL, ndhF, trnL-UAG/ndhD, and ycf1, were identified among the 10 Lindera species. In addition…

Comparative Chloroplast Genomics of Litsea Lam. (Lauraceae) and Its Phylogenetic Implications
The whole chloroplast genome sequence of Litsea auriculata is sequenced and it is 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.
The complete plastid genome of an evergreen tree Litsea elongata (Lauraceae: Laureae)
Phylogenomic analysis based on 39 complete plastomes of Laureae in the family Lauraceae supports the close relationships among L. elongata, L. japonica, and L. pierrei.
The complete chloroplast genome of Lindera pulcherrima var. hemsleyana (Lauraceae)
Phylogenetic analysis of cp genomes from 24 species of Lauraceae revealed that cp genomes of L. pulcherrima var.
Plastid phylogenomics improve phylogenetic resolution in the Lauraceae
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.
Conflicting phylogenetic signals in plastomes of the tribe Laureae (Lauraceae)
This study highlights the importance of evaluating the influence of non-coding regions of the plastome on tree topology and emphasizes the necessity of examining discordance among different plastid loci in phylogenetic studies.
Chloroplast Phylogenomic Analyses Reveal a Maternal Hybridization Event Leading to the Formation of Cultivated Peanuts
This research could facilitate a better understanding of the taxonomic status of various Arachis species/accessions and the evolutionary relationship among them, and assists in the correct and efficient use of germplasm resources in breeding efforts to improve peanuts for the benefit of human beings.
Distinct late Pleistocene subtropical-tropical divergence revealed by fifteen low-copy nuclear genes in a dominant species in South-East China
It is likely that L. aggregata is originated in Southwest-South China and experienced hierarchical dispersal from south to north, and the South China Sea land bridge has dual role in connecting or isolating Taiwan and mainland populations since the last glaciation.


Comparative chloroplast genomics and phylogenetics of nine Lindera species (Lauraceae)
The results showed that these Lindera species grouped into two or four sub-clades, and that two Litsea species and Laurus nobilis were located in the same sub-Clade as five LinderA species, which support a close relationship between the genera Laurus, Lindersa, and Litsea.
Complete plastid genome sequences of three tropical Alseodaphne trees in the family Lauraceae
Phylogenetic analyses based on 12 complete plastomes of Lauraceae species confirm a monophyletic Persea group comprising species of Alseodaphne, Phoebe, Persea and Machilus.
Evolutionary Comparisons of the Chloroplast Genome in Lauraceae and Insights into Loss Events in the Magnoliids
Using phylogenetic analysis and structural comparisons, different loss events occurred in different lineages of the Laurales, and fragment loss events in the IR regions have largely driven the contraction of the plastome in the Lauraceae.
Complete chloroplast genome sequence of the avocado: gene organization, comparative analysis, and phylogenetic relationships with other Lauraceae
The complete chloroplast sequence of the avocado (Persea americana Mill.), a popular tropical fruit tree, was determined in this study and the plastomes of Lauraceae are extremely evolutionarily conservative, with only 0.32% sequence divergence, which is surprisingly low for angiosperms.
Phylogeny of Litsea and related genera (Laureae-Lauraceae) based on analysis of rpb2 gene sequences
The phylogenetic analyses of rpb2 data resulted in better resolved tree topologies compared to those based on cpDNA or nrITS data, and revealed that the genus Lindera is not a monophyletic group.
Comparative analysis of complete chloroplast genome sequences of two subtropical trees, Phoebe sheareri and Phoebe omeiensis (Lauraceae)
Phoebe is an economically important genus from the family Lauraceae. It is widely distributed in tropical and subtropical Asia, but systematics of the genus is unclear, and currently there is no
Phylogenetic Relationships of the Litsea Complex and Core Laureae (Lauraceae) Using ITS and ETS Sequences and Morphology1
The results suggest that the use of two- versus four-celled anthers for Laureae generic delimitation has resulted in polyphyletic or paraphyletic genera, and the character of dimerous versus trimerous flowers is of only limited phylogenetic value.
Complete chloroplast genome sequences of two endangered Phoebe (Lauraceae) species
The analysis showed the extremely conserved structure of chloroplast genomes with surprisingly little variations at the LSC/ir and SSC/IR boundaries, suggesting an extraordinarily low level of sequence divergence.
Phylogeny and Historical Biogeography of Lauraceae: Evidence from the Chloroplast and Nuclear Genomes
Findings support Laurasian ancestry for most extant Lauraceae, with their considerable neotropical representation primarily derived from Early Miocene radiation of the Ocotea complex upon reaching South America.
Comparative analysis of complete chloroplast genome sequences of two tropical trees Machilus yunnanensis and Machilus balansae in the family Lauraceae
To better understand the mutation patterns in the chloroplast genome of Machilus, the complete plastomes of two species were sequenced and 297 mutation events, including one micro-inversion in the ccsA-ndhD region, were accurately located.
