Morphology, phylogeography, phylogeny, and taxonomy of (Apiaceae).

Background: The genus is endemic to China and belongs to the Apiaceae family, which is widely distributed in the Himalaya-Hengduan Mountains (HHM) region. However, its morphology, phylogeny, phylogeography, taxonomy, and evolutionary history were not investigated due to insufficient sampling and lack of population sampling and plastome data. Additionally, we found that was not similar to members but resembled species in morphology, indicating that the taxonomic position of needs to be re-evaluated.

Peering through the hedge: Multiple datasets yield insights into the phylogenetic relationships and incongruences in the tribe Lilieae (Liliaceae).

The increasing use of genome-scale data has significantly facilitated phylogenetic analyses, contributing to the dissection of the underlying evolutionary mechanisms that shape phylogenetic incongruences, such as incomplete lineage sorting (ILS) and hybridization. Lilieae, a prominent member of the Liliaceae family, comprises four genera and approximately 260 species, representing 43% of all species within Liliaceae. They possess high ornamental, medicinal and edible values.

Plastid phylogenomics contributes to the taxonomic revision of taxa within the genus L. and acceptance of two new members of the genus.

Introduction: The genus L. is a taxonomically complicated taxa within Apiaceae, as its high variability in morphology. Although taxonomists have performed several taxonomic revisions for this genus, the interspecific relationships and species boundaries have not been satisfactorily resolved, especially for those endemic to China.

Background: The genus Libanotis Haller ex Zinn, nom. cons., a contentious member of Apiaceae, encompasses numerous economically and medicinally significant plants, comprising approximately 30 species distributed across Eurasia.

, a new species of Primulaceae from Tibet of China.

We present a description of a newly discovered species, , found in southern Xizang, China. Additionally, we explore distinctive morphological characteristics that aid in its taxonomy. The new species belongs to sect.

Backbone phylogeny and adaptive evolution of s. l.: New insights from phylogenomic analyses of complete plastome data.

is a taxonomically challenging taxon of Apiaceae, as its circumscription and composition remain controversial for morphological similarities with several related genera, leading to a dispute between in the broad sense and strict sense. While evidence from previous molecular studies recognized plural branching lineages within the s. l.

Morphological and molecular evidence gives insight into the taxonomic position of (Apiaceae, Selineae).

In this study, morphological and molecular evidences were combined to determine the taxonomic position of Hand.-Mazz. Morphologically, is similar to the species of the genus in having fibrous remnant sheaths at the stem base, pinnate and linear coexisted bracts, strongly compressed dorsally mericarps, filiform median and lateral ribs, winged marginal ribs, numerous vittae in each furrow and commissure, but can also be easily distinguished from members of by its hispid fruit and linear-lanceolate bracteoles.

Phylogeny and adaptive evolution of subgenus Rhizirideum (Amaryllidaceae, Allium) based on plastid genomes.

The subgenus Rhizirideum in the genus Allium consists of 38 species worldwide and forms five sections (A. sect. Rhizomatosa, A.

The plastid genome of twenty-two species from Ferula, Talassia, and Soranthus: comparative analysis, phylogenetic implications, and adaptive evolution.

Background: The Ferula genus encompasses 180-185 species and is one of the largest genera in Apiaceae, with many of Ferula species possessing important medical value. The previous studies provided more information for Ferula, but its infrageneric relationships are still confusing. In addition, its genetic basis of its adaptive evolution remains poorly understood.

Evidence from Phylogenomics and Morphology Provide Insights into the Phylogeny, Plastome Evolution, and Taxonomy of .

Pimenov is one of the segregate genera of sensu lato within the Apiaceae. The phylogenetic position and morphological delimitation of have been controversial. In this study, we used plastid genome (plastome) and nuclear ribosomal DNA (nrDNA) sequences to reconstruct the phylogeny of , along with comparative plastome and morphological analyses between and related taxa.

The phylogeny of Seseli (Apiaceae, Apioideae): insights from molecular and morphological data.

Background: The genus Seseli L., which consists of 125-140 species distributed in the Old World from western Europe and northwestern Africa to China and Japan, is one of the largest and most taxonomically difficult genera of Apiaceae Lindl. Although several previous studies have been conducted on Seseli based on limited morphological characteristics and molecular fragments, a robust and comprehensive phylogeny of Seseli remains elusive.

Plastid phylogenomic insights into relationships, divergence, and evolution of Apiales.

Members of Apiales are monophyletic and radiated in the Late Cretaceous. Fruit morphologies are critical for Apiales evolution and negative selection and mutation pressure play important roles in environmental adaptation. Apiales include many foods, spices, medicinal, and ornamental plants, but the phylogenetic relationships, origin and divergence, and adaptive evolution remain poorly understood.

Phylogenetic position of (Apiaceae, Apioideae): evidence from molecular data and carpological characters.

(Apiaceae, Apioideae) is now considered to have an East-Asia and Sino-Himalaya distribution. The genus was not recognized as a natural and separate genus and was treated as a synonym of both in and since first established, though Pimenov have made many taxonomic revisions to , phylogenetic relationships between and have been in dispute. Thirty-four plastomes and 35 nrITS from Apioideae were analysed by RAxML and MrBayes to reconstruct the phylogenetic relationships, along with carpology of 10 species and comparative analyses of 17 plastomes to investigate the evidence supporting the independence of .

The complete plastomes of seven Peucedanum plants: comparative and phylogenetic analyses for the Peucedanum genus.

Background: The Peucedanum genus is the backbone member of Apiaceae, with many economically and medically important plants. Although the previous studies on Peucedanum provide us with a good research basis, there are still unclear phylogenetic relationships and many taxonomic problems in Peucedanum, and a robust phylogenetic framework of this genus still has not been obtained, which severely hampers the improvement and revision of taxonomic system for this genus. The plastid genomes possessing more variable characters have potential for reconstructing a robust phylogeny in plants.

Phylogeny, Age, and Evolution of Tribe Lilieae (Liliaceae) Based on Whole Plastid Genomes.

Tribe Lilieae, encompassing , , , and , includes economically important crops with a horticultural and medicinal value. It is considered to be a core lineage of Liliaceae, but phylogenetic relationships within it, and the timing of the origin of individual clades, remain incompletely resolved. To address these issues, we reconstructed the evolutionary history of the tribe.

Phylogeny and Comparative Analysis for the Plastid Genomes of Five (Liliaceae).

Species of (Liliaceae) are of great horticultural importance and are distributed across Europe, North Africa, and Asia. The Tien Shan Mountain is one of the primary diversity centres of , but the molecular studies of species from this location are lacking. In our study, we assembled four plastid genomes from the Tien Shan Mountains, , , , and , combined with the plastid genome of to compare against other Liliaceae plastid genomes.
