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.
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.
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).
