Graduated from Federal University of Pelotas (FAEM - UFPEL, Pelotas, RS, Brazil) in 1990, received a Master degree in Genetics and Plant Breeding from University of São Paulo (Dr. Akihiko Ando and Dr. Francisco Javier Zapata-Arias Lab at ESALQ - USP, Piracicaba, SP, Brazil) in 1994 and received a Ph.D. in Plant Physiology and Biochemistry from Washington State University (Dr. Ryan Lab at IBC - WSU, Pullman, WA, USA) in 2000. In 2003 I was awarded a "Young Researcher Grant" from São Paulo Research Foundation (FAPESP, Piracicaba, SP, Brazil), at which time I joined the University of São Paulo (ESALQ -USP, Piracicaba, SP, Brazil) as associate researcher. In 2009 I joined the faculty of the Department of Biological Sciences in the same university where I am now an Associate Professor in Biochemistry. (Source: Lattes Curriculum)

Over the past few decades, functional studies have led to remarkable advances in characterizing the interactions between plants and their associated organisms, whether harmful or beneficial. The necessary simplification of study models (typically, a plant interacting with a single pathogen/insect pest or symbiotic agent) made it possible to identify the main signaling pathways (pathogenic…
RALF signaling peptides negatively regulate cell elongation and inhibit root growth. The membrane protein FERONIA has been recently identified as AtRALF1 receptor, however, this same protein has already been described as positive regulator of cell expansion, playing a role in a brassinosteroid parallel signaling pathway. Arabidopsis has nine RALF isoforms with high homology with the orig…
In our lab we are interested in two major research areas: 1) intracellular protein trafficking and, 2) plant-herbivore interactions. These topics have been successfully established over the years and we've obtained international recognition for our research. Our contribution to these fields can be seen in international peer-reviewed journals and also as a referee to world-class journals a…
Plant-insect-pathogen interactions are models for studying the complex multitrophic relationships that take place in the field. These relationships are often highly dependent on each other. This work seeks to understand the relationship between Fusarium verticillioides and Diatraea saccharalis at the molecular level using the Zea mays plant as a model. The investigation of the genes and p…
In recent decades, peptides with similar action to hormonal peptides in animals have been discovered in plants. These signaling peptides are involved with defense response, stress response, differentiation and development. An example of these signaling peptides is RALF, a ubiquitous peptide in the plant kingdom and it is involved with the regulation of cell expansion. The isoforms AtRALF2…
Peptide hormones are signals that determine the growth, development and defense in plants. RALF (Rapid Alkalinization Factor) is a peptide hormone ubiquitous in the plant kingdom and is involved in cell expansion. RALF peptides in Arabidopsis are organized in a 37 members multigene family, some of them are tissue-specific and others are expressed throughout the plant. Our main goal is to …
RALF are plant secreted peptides of approximately 5kDa that have hormonal characteristics. RALF peptide hormones were isolated and identified for the first time in tobacco using the alkalinization assay and they are involved in cell elongation. Although their mechanism of action is still unknown, the presence of RALF peptides in all plant kingdom suggests a role in basic cellular process.…

Fusarium verticillioides is a major phytopathogen affecting crops like maize (Zea mays) and other grasses, causing significant economic losses worldwide. Its infection results in various symptoms across all plant development stages, from pre- to post-harvest, leading to stalk and ear rot and the production of toxic secondary metabolites such as fumonisins. Moreover, the sugarcane borer, D…
This project is part of a PhD scholarship from FAPESP that was implemented in July 2010 under the title "RALF and the brassinosteroid receptor complex: interaction of peptide AtRALF1 and protein BAK1, a membrane protein receptor BRI1 associated kinase”. RALF peptides are signaling molecules with hormonal characteristics and since their discovery, efforts have been done towards the identif…
