Research Summary:

Academic Interests: Molecular Genetics and Systems Biology dissection of complex plant biological processes involved in plant abiotic stress interaction and crop yield.

Research Focus & Techniques of Expertise: Research in the Pereira laboratory is focused on the identification of genes for crop traits and their utilization in rice and other plants. Our objective is to develop an understanding of the molecular genetic basis of crop traits, studied in an interdisciplinary approach, utilizing the rapidly increasing information in plant genomics and other high-throughput technologies.

Present research is on analysis of the rice, maize and Arabidopsis stress transcriptome and integration of the data into gene coexpression/interaction networks. Identification of gene modules involved in stress response lead to the selection of candidate genes that are used for validation by knockout mutants, overexpression lines, genome-wide association and allele expression analysis. Regulatory genes have been identified for grain yield and lignocellulose-biomass synthesis, and are being followed up by analysis of the underlying protein-protein and protein-DNA interaction network.
