Introduction:

The world’s rapidly expanding populations have created a sense of urgency regarding global agricultural output, which needs to expand by at least 70% by the year 2050. Plants will provide a significant proportion of the world’s food supply. This international conference focuses on a group of plant enemies that have an unique style of attack. Instead of simply removing plant tissue, survival, growth and reproduction are enhanced by manipulating the plant to create specialized nutritional resources. This attack strategy can have serious consequences for both natural and agro-ecosystems. Mechanisms of reprogramming host plants remain largely unknown but clearly involve secreted effectors that are applied during attack. Options for defense against reprogrammers include effector-triggered immunity. Historically the phylogenetically diverse plant enemies that reprogram plants have been studied by different groups. This interdisciplinary meeting will bring together the complementary strengths of key international laboratories to discuss advances in our understanding of the enemies that reprogram plants and their associated symbionts, the options that plants have for their defense, and the evolutionary potential of enemies to adapt to plant defense.

 

    Main topics of the conference:

    • Enemy attack: identity and function of effectors produced by insects, nematodes, and pathogens

    • Plant responses: phytohormone signalling, nutrient mobilization, cellular reorganization, and defence

    • Ecological consequences of reprogramming plants and cascading effects in the ecosystem

    • Contributions of microbial symbionts to plant-reprogrammer interactions
