University of Campinas, UEC, Brasil


The University of Campinas, Brazil, is one of the major public universities in Brazil. The research lines of the Center for Molecular Biology and Genetic Engineering deal with several fields on human, animal, microorganisms and plant biology. The Plant Molecular Biology Laboratory (PMBL) has a strong background in the study of gene regulation and has cooperations with several research groups in Brazil, Latin America and Europe. The PMBL is one of the two laboratories directing the first genomic project in Latin America, and is the coordinator of the Brazilian Sugarcane EST project. The research center also has a deep commitment with education, and several undergraduated, master and PhD students develop their projects under the supervision of Professors that are part of the staff.

Dr. Marcelo Menossi Teixeira is a Professor at the University of Campinas. Dr. Paulo Arruda is also a Professor and is the director of the research center. In the last three years, both have been directing the research on the characterization of the molecular and biochemical basis of Aluminium tolerance in maize. These activities are being carried out in the frame of an INCO-1 project, coordinated by Dr. Pere Puigdomènech (Spain), in cooperation with the groups of Dr. Herrera-Estrella (Mexico) and Dr. Thomas Altmann (Germany). Under the direction of Dr. Menossi, several Al-induced genes were isolated and their expression patterns were characterized in two maize lines contrasting in Al resistance. Dr. Arruda directed the mapping studies and it was found that there are two main genes controlling Al resistance in these maize lines. Dr. Menossi and Dr. Arruda will develop the tasks described in the workpackages 9 and 10.

Dr. R. A. Jorge is a Professor of the Chemical Institute at the University of Campinas. He has been working with the role of organic acids in the Al resistance observed in tropical maize germplasms. He will be responsible for the characterization of the oxidative stress that takes place in response to Al in maize (workpackage 6).
