To enable the application of beneficial microorganisms in plant production systems MICRO.1 aims to improve our understanding of plant-microbe-environment interactions. At field scale we study the impact of farming practice on plant health and productivity and how the structure and function of the plant-associated microbiota serves as an intermediary in this process. At laboratory scale we use experimental systems of horticultural model plants to study the interplay between abiotic (especially drought and salinity) and biotic (especially soil-borne fungal pathogens) stress, the plant microbiota and plant health and productivity. MICRO.1 contributes to the overall goal of the institute by advancing our understanding of the impact of microorganisms on plant systems, which may accelerate the development of more sustainable horticulture.
MICRO.1 Principles of integrated pest management
MICRO.1 Principles of integrated pest management Head of RG MICRO.1: Dr Rita Grosch
Environmental stress is responsible for considerable crop yield and quality loss in plant production systems. Plant-associated microorganisms may offer a sustainable means to improve plant health and productivity, e.g. by conferring stress tolerance to both biotic and abiotic stress and by promoting plant growth, but this potential is still largely untapped.
