The plant microbiome plays a major role in crop health and productivity, and this PMBWC 2027 session explores plant–microbe interactions and how microbial communities can be managed and engineered. Plants live closely with large communities of bacteria and fungi in the soil around their roots, inside their tissues and on their leaves. These microbes influence nutrient uptake, growth and disease resistance. Research shows that the plant's own genetics affects which microbes it hosts. Studies have shown that resistant and susceptible varieties of the same crop can attract very different microbial communities, and these differences can affect how well the plant resists disease. Understanding these relationships makes it possible to design microbial treatments, choose varieties that support helpful microbes and manage soils in ways that improve plant health.
This session covers root, leaf and internal plant microbiomes, plant–microbe signalling, synthetic microbial communities and breeding for beneficial microbial associations. The focus is on using knowledge of plant–microbe interactions to improve crop health and productivity.
