Team Leader: Maria Fátima Grossi-de-Sa
Laboratory Activities with INCT PlantStress Biotech
The Plant-Pest Molecular Interaction Laboratory (LIMPP) is coordinated by Dr. Maria Fatima Grossi-de-Sa, in which research interests involve basic and applied sciences, focusing on the plant-pest molecular interactions (pathogens and insect-pests) to develop novel crop protection strategies, mainly for cotton and soybean. The LIMPP group’s research is recognized for their expertise in plant biotechnology using functional genomics, notably working on biotechnological aspects of the RNA interfering (RNAi) mechanism applied to insect-pests and phytonematodes. Other current research interests also encompass the exploration of new plant genetic transformation and genome editing technologies, novel regulatory sequences for genetic engineering of crop plants against insect-pests and phytonematodes controls and drought tolerance, and production of recombinant proteins.
• Search for novel genes/molecules and peptides to be applied in the control insect-pests of cotton and soybean plants.
• Search for the target genes/molecules of plant parasitic nematodes (Meloidogyne spp., Rotylenchus reniformis, Aphelenchoides spp.) to be applied in gene silencing approaches.
• Search for target genes/molecules of contrasting soybean genotypes (resistant/susceptible to Meloidogyne spp.) to be applied to the genetic engineering of crop plants using genome editing technologies.
• Search for gene/molecules and small RNAs in pest and drought resistant/tolerant plant genotypes that could be involved in the response to biotic and abiotic stresses (cross-stress).
• Validation of the new prospected biotech assets using overexpression of molecules or gene silencing approaches in plant models.
• Developing the genetic engineering of crop plants (cotton, soybean, sugarcane) using molecules/dsRNAs overexpression, gene silencing, and genome editing approaches for traits that include pest control, increase in biomass, and drought tolerance.
