As part of the Pre-HLB Project, Fundecitrus and partner institutions promote professional exchanges for research on greening. In recent months, Fundecitrus received a researcher from the University of Amsterdam (Netherlands) and sent a researcher to the University of Valencia (Spain).

Relying on the expertise of more than 100 researchers and technicians from 24 institutions in ten countries, the Pre-HLB Project seeks solutions to control greening, in a European Union initiative to encourage research and innovation – although the disease is not present in Europe, the project establishes actions to prevent the arrival of greening. In Brazil, Fundecitrus, Embrapa and Unesp-Jaboticabal are part of the partnership.

Fundecitrus participates in several short, medium and long-term subprojects, focusing on research to identify and incorporate resistance to greening in commercial varieties and which also seek to understand the relationship between bacteria, insect vectors and citrus plants.

Around three years ago, Fundecitrus studies confirmed resistance to greening in Microcitrus and Eremocitrus plants. Since then, hybrid plants are being generated by crossing these resistant species with susceptible varieties and research is being carried out to identify the genes that confer resistance to the disease.

In recent exchanges, studies and analyzes are being developed on candidate genes for resistance and also on metabolic and molecular interactions (metabolomics) between bacteria/plant and bacteria/psyllid. These activities are important to accelerate the achievement of results and to integrate activities between the different research groups.   

At the end of May, a group of researchers from Spain should also visit Fundecitrus.
