🎯 Summary: This video shows the research on plant disease susceptibility genes for the "Dance your PhD contest" 2019/2020. The soil is full of microbes. However, some microbes like Verticillium dahliae are pathogenic on tomato. V. dahliae causes high annual losses in many crops. Therefore, a novel breeding approach is focusing on disease susceptibility genes (S genes). S genes are genes that make a plant susceptible. They are ‘abused’ by the pathogen to establish disease. Identification of these genes is essential to understand plant – pathogen interaction. Alterations of S gene can result in loss-of-susceptibility. That’s why, targeted genome editing (CRISPR-Cas9) is used to alter S genes. Targeted alterations can positively affect plant-pathogen interaction. This is because altered S genes cannot be ‘abused’ by V. dahliae anymore to cause disease. Such loss-of-susceptibility can be used to breed for resistance. Instead of adding resistance to a plant, susceptibility is taken away from the plant. Sometimes, less is more!
