Abstract:
The legume tribe Amorpheae comprises eight genera and ca. 240 species exclusive to the New World. We performed parsimony and maximum likelihood phylogenetic analyses based on sequence data from the nuclear gene CNGC4, the chloroplast trnK/matK genes and the nuclear ribosomal ITS regions. Our goal was to infer the generic-level phylogenetic relationships of the tribe with an expanded sampling on Dalea, a genus that comprises nearly 70 % of the species of the tribe. We corroborated that the tribe Amorpheae is formed by the Daleoid clade, comprising Dalea, Marina, and Psorothamnus, and the Amorph

Abstract:
This study addresses the phylogenetic relationships within the genus Dianthus in South Africa, employing a molecular analysis approach and the distribution pattern of the representatives of the genus. A robust phylogenetic tree comprising three plastids (trnH-psbA, trnK-matK, and trnK-psbA) and a nuclear region was assembled based on 94 taxa of Dianthus and Petrorhagia species using Mr Bayes analysis. Furthermore, distribution maps for each Dianthus species were generated using QGIS. Our results have revealed Dianthus as monophyletic when Petrorhagia is used as an outgroup. Four strongly suppo

Abstract:
Parsimony and SplitsTree analyses of ITS and 5′ trnK/matK sequence data were used to assess the extent of hybridisation and its evolutionary significance in the New Zealand endemic genus Hoheria A.Cunn. The seven species of Hoheria form a monophyletic group along with the New Zealand endemic genus Plagianthus J.R.Forst. &amp; G.Forst. and the Australian endemics Asterotrichion Klotzsch. and Gynatrix Alef. This strongly supported clade is sister to a clade of Australian species of Lawrencia Hook. The inferred evolutionary history of Hoheria suggests that the extant species are derived from a co

Abstract:
Natural hybridization has been considered a source of taxonomic complexity in Cryptocoryne. A combined study of DNA sequencing data from the internal transcribed spacer (ITS) of nuclear ribosomal DNA and the trnK-matK region of chloroplast DNA was used to identify the parents of Cryptocoryne putative hybrids from Peninsular Malaysia. Based on the intermediate morphology and sympatric distribution area, the plants were tentatively identified as the hybrid Cryptocoryne ×purpurea nothovar. purpurea. The plants were pollen sterile and had long been considered as hybrids, supposedly between two rel

Cananga odorata (Lam.) Hook.f. &amp; Thomson, a member of the Annonaceae family, has become widespread from the Indo-Malayan region to northern Australia and Malaysia. This plant has economic value because it produces essential oils used in the perfume and food industries. No research existed yet related to DNA barcoding to see intraspecific variations in C. odorata.

AbstractMolecular autograph of trn/mat-K gene was used as one of the important candidate marker in addressing the questions of systematics and barcoding of medicinal plants. Features of trn/mat-K gene in Isodon rugosus (Lamiaceae) were assessed for the first time (NCBI GenBank Accession Number: MH939199.1). Sequence of 756 bp length was amplified by the universal matK primers (matK472F and matK1248R) in the cpDNA of the plant. It was reported to contain trnK gene (&gt;1…..50; &gt;746…..756), partial sequence; and matK gene (&gt;51…..745), partial coding DNA sequence. Alignment search and analy

Abstract:
The first species of the genus Pteroglossa is recorded from Peru. Pteroglossa acalcarata, a new orchid species from the eastern slope of the Peruvian Andes, is described and illustrated. It is similar in overall floral morphology to Pteroglossa macrantha, which is its closest relative according to a phylogenetic analysis of nucleotide sequences of plastid matK-trnK region presented here. However, P. acalcarata is distinguished from P. macrantha by its pubescent petals (vs. glabrous), inconspicuous lateral lobes of the labellum free from the sides of the column and absence of a spur.

The recent call to reconstruct a detailed picture of the tree of life for all organisms has forever changed the field of molecular phylogenetics. Sequencing technology has improved to the point that scientics can now routinely sequence complete plastid/mitochondrial genomes and thus, vast amounts of data can be used to reconstruct phylogenies. These data are accumulating in DNA sequence repositories, such as GenBank, where everyone can benefit from the vast growth of information. The trend of generating genomic-region rich datasets has far outpaced the expasion of datasets by sampling a broade
