Resistance breeding is getting more important to keep agriculture sustainable. To be able to breed for resistance traits, it is essential to have the ability phenotype the plants. Infection assays (bioassays) are often not desired at a breeding company for risk of contamination and spread of disease. At Iribov we offer this service for several plant-pathogen combinations, and can develop a new protocol. We developed phytotrons where we can grow plants under controlled conditions. This way we can perform infection experiments under a broad range of environmental conditions year-round.
