A DNA barcode for land plants
TLDR
The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.
An expanded plastid DNA phylogeny of Orchidaceae and analysis of jackknife branch support strategy.
TLDR
It is found that support values plateau rapidly with increased search effort, and tree bisection-reconnection swapping in a single search replicate per jackknife replicate and saving only two trees resulted in values that were close to those obtained in the most extensive searches.
Biodiversity and Conservation of Plants in Brazil
TLDR
Coordinated efforts to catalog Brazil's flora are in progress and include projects such as the conservation priority-setting workshops of the Brazilian Ministry of the Environment; development of threatened species lists for plants; and the assembly of type data on species of northeastern Brazil through the Darwin Initiative, which greatly assist in increasing knowledge.
Amazon plant diversity revealed by a taxonomically verified species list
TLDR
A comprehensive dataset of Amazonian seed plant species from published sources that includes falsifiable data based on voucher specimens identified by taxonomic specialists is assembled, providing a valid starting point for macroecological and evolutionary studies aimed at understanding the origin, evolution, and ecology of the exceptional biodiversity ofAmazonian forests.
An overview of the phylogenetic relationships within Epidendroideae inferred from multiple DNA regions and recircumscription of Epidendreae and Arethuseae (Orchidaceae).
TLDR
Phylogenetic relationships within the epidendroid orchids with emphasis on tribes Epidendreae and Arethuseae were assessed with parsimony and model-based analyses of individual and combined DNA sequence data, finding a well-resolved and supported consensus.
A phylogenetic study of Laeliinae (Orchidaceae) based on combined nuclear and plastid DNA sequences.
TLDR
By using combined plastid and nuclear DNA data in conjunction with mixed-models Bayesian inference, it is possible to delimit smaller groups within Laeliinae and discuss general patterns of pollination and hybridization compatibility.
A preliminary study of genetic variation in populations of Monstera adansonii var. klotzschiana (Araceae) from North-East Brazil, estimated with AFLP molecular markers.
TLDR
The gene pools detected within an overall pattern of clinal variation suggest distinct episodes of gene flow, possibly correlated with past humid forest expansions, and reinforce the importance of conserving the endangered brejo forests.
Molecular phylogenetics of the species-rich genus Habenaria (Orchidaceae) in the New World based on nuclear and plastid DNA sequences.
DIVERSIFICATION OF ASCLEPIADOIDEAE (APOCYNACEAE) IN THE NEW WORLD1
TLDR
Plastid sequences of trnL-F are used to estimate the age of biogeographical events in New World Asclepiadoideae and suggest that the subfamily arose somewhere in the Old World in the Late Eocene and that there were at least four independent episodes of dispersal to the New World.
Molecular and cytological examination of Calopogon (Orchidaceae, Epidendroideae): circumscription, phylogeny, polyploidy, and possible hybrid speciation.
TLDR
Using nuclear internal transcribed spacer ribosomal DNA sequences, amplified fragment length polymorphisms, chloroplast DNA restriction fragments, and chromosome counts, a phylogenetic and taxonomic study of the orchid genus Calopogon R.Br.
