Introduction
I am currently interested in plant phylogeny and population genetics of plants and their interface with evolution, phylogeography, and plant morphology as quantified by multivariate and geometric morphometrics. Currently PI of a molecular biology laboratory in the topics above, with emphasis in Orchidaceae, but also other relevant groups for understanding the evolution of the eastern Brazilian biota and Neotropical biogeography.

Article
Since the last classification of Orchidaceae in 2003, there has been major progress in the determination of relationships, and we present here a revised classification including a list of all 736 currently recognized genera. A number of generic changes have occurred in Orchideae (Orchidoideae), but the majority of changes have occurred in Epidendro...

A new classification for the 114 species Cattleya is proposed, based on and compatible with previously published nuclear, plastid and combined phylogenetic trees. Cattleya is divided into four subgenera, three sections and five series. A key to the infrageneric categories and a table listing all species and their placement is presented.

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 from ITS nuclear ribosomal DNA and plastid trnL intron, the trnL-F spacer, matK (gene and spacers), and rbcL regions. Despite the absence of b...

DNA barcoding involves sequencing a standard region of DNA as a tool for species identification. However, there has been no agreement on which region(s) should be used for barcoding land plants. To provide a community recommendation on a standard plant barcode, we have compared the performance of 7 leading candidate plastid DNA regions (atpF–atpH s...

Laeliinae are a neotropical orchid subtribe with approx. 1500 species in 50 genera. In this study, an attempt is made to assess generic alliances based on molecular phylogenetic analysis of DNA sequence data. Six DNA datasets were gathered: plastid trnL intron, trnL-F spacer, matK gene and trnK introns upstream and dowstream from matK and nuclear I...

O CRISPR/Cas9 é um mecanismo de memória adaptativa bacteriano que se apresenta como uma das plataformas mais eficazes de edição genética, permitindo manipular de forma precisa qualquer sequência genômica. Ao longo de uma década foram feitas inúmeras publicações utilizando esta técnica em diversos modelos biológicos, com diferentes finalidades. A Dr...

The economically important cotton and cacao family (Malvaceae sensu lato) have long been recognized as a monophyletic group. However, the relationships among some subfamilies are still unclear as discordant phylogenetic hypotheses keep arising when different sources of molecular data are analyzed. Phylogenetic discordance has previously been hypoth...

In Malpighiaceae, Hiptage represents one of the seven past dispersal events from the Neotropics to the Paleotropical region, being by far the most widely diversified and distributed genus of Paleotropical Malpighiaceae. In this study, we tested the current infrageneric classification of Hiptage with a dated and calibrated molecular phylogeny. We al...
Article
The pollination process and breeding system of Pachygenium bonariense and Pachygenium pteryganthum were documented for native populations from Rio Grande do Sul, Brazil. The flowers secrete nectar (on average with 65% to 67% of the concentration of total sugars), which is concealed into an incurved spur. Both species are pollinated by native, large...

Lippia origanoides Kunth. is a medicinal plant that is widely available in the Northeast region of Brazil and is known as “alecrim-d’angola”. However, there is no information available on the genetic variability of this species in the region. Thus, the current study was aimed to analyze the genetic diversity and structuring of L. origanoides popula...

The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...

Pseudolaelia Campos Porto & Brade (1935: 209) is a small orchid genus in subtribe Laeliinae. Its phylogenetic affinities place it near several small, endemic genera which constitute an isolated lineage in eastern Brazil, together with Adamantinia Van den Berg & Gonçalves (2004: 231), Constantia Barbosa Rodrigues (1877: 78), Isabelia Barbosa Rodrigu...

In the past two decades, Malpighiaceae has gone through unprecedented changes in classification due to molecular phylogenetic studies.

We investigated the biogeography of Stigmaphyllon, the second-largest lianescent genus of Malpighiaceae, as a model genus to reconstruct the age and biogeographic history of the Brazilian Atlantic Rainforest (BAF). Few studies to date have focused on the tertiary diversification of plant lineages in the BAFs, especially on Stigmaphyllon. Phylogenet...

In this study, we analyse a species complex in Epidendrum, a mega-diverse Neotropical orchid genus, that is formed by the 11 Brazilian species of the E. difforme group. Although this group (c. 100 taxa) exhibits relatively high levels of floral variation, the Brazilian species are similar, making delimitation problematic. Here we combine molecular...

In the present paper we provide lectotypifications for the names Prosthechea bohnkiana, P. carrii, and P. elisae, and epitypes for the first two. These typifications were necessary due to gross disagreement between the available specimens and the data provided by the authors in the protologues of these names.

We present nomenclatural and taxonomic studies of selected species and names of Neotropical Orchidaceae currently placed in Bifrenaria, Cleistes, and Pleurothallis, but once classified in ten different genera.

Understanding the composition of the type specimen of Pseudolaelia corcovadensis is very important for establishing its taxonomic circumscription.

A careful...

The taxonomy of some groups of plants is challenging, and the strict use of morphological characters may not be enough to solve problems of species delimitation.

Two of the major challenges in plant evolutionary studies are the development of orthologous molecular markers variable enough to resolve interspecific relationships and generating such data for a large number of species in 'me-ga-diverse' lineages. One such lineage is the Neotropical orchid genus Epidendrum, as our recent estimates indicate that i...

Hybridization and introgression are considered important processes in the evolution of plant species and populations. Their outcomes are unpredictable and can range from increased genetic variation that could then be selected, therefore accelerating speciation, to the opposite process, when high amounts of admixing could homogenize populations from...
