Resistance genes

Pathogens are a major threat for the maturation of field crops, fruits and ornamentals. We offer genotyping services for screening programs to detect those crops resistant to some of the most common pathogens, like tomato spotted white virus or the tomato mosaic virus.

A collaboration with our partner, Sequentia Biotech in Spain, has led to the development and validation of high-quality DNA markers for a selection of resistance genes. The initial focus has been on Tomato, other species are continuously developed.

Please contact us if you want to add your favorite resistance gene to our priority list. Predictability of the markers depends on the germplasm provided by the client. Additional validation and R&D could be necessary before large scale screening services can be executed.

Currently, the following resistance genes are available:
