SUMMARY:James Dalling Seed – Fungal Relationships
DESCRIPTION:Plant-fungal interactions are ubiquitous. For a forest ecologist interested in how plant species are distributed  compete for resources  and defend against their natural enemies  fungi are difficult  if not impossible  to ignore. Furthermore  fungi are now known to infect all plant tissues – from their roots and sapwood to flowers  leaves and seeds. In many cases these internal infections of plants by ‘endophytic fungi’ occur either without adverse impacts on the plant host  or with impacts that vary depending on the identity of the host species. James will review the breadth of endophytic fungal infections  and some of the impacts these have on their hosts. He will then describe the work he and his team are conducting in lowland tropical forest in Panama on the fungi that infect seeds of tree species that depend on soil seed banks to successfully regenerate after disturbance. Using a combination of carbon-dating  seed burial experiments  fungal culturing and inoculation experiments they have found a high degree of host specificity of seed fungi. These fungal infections can be viewed as the ‘primary symbionts’ that plants encounter  with impacts on seed germination and survival that are a consequence both of the fungi themselves  as well as bacteria that live within the fungal hyphae. Understanding how seed infecting fungi impact seed survival patterns can help us understand how tropical forest diversity is maintained  and also has applications for the protection of crop seeds and the management of weed species in agricultural systems. James Dalling is a Professor of Tropical Ecology at the University of Illinois at Urbana-Champaign  and a Research Associate at the Smithsonian Tropical Research Institute (STRI) in Panama. He completed an undergraduate degree in Botany at Oxford University and a PhD at Cambridge University studying the regeneration of tropical montane forests in Jamaica. He moved to Panama as a post-doctoral researcher in 1992 and spent eight years working on seed dispersal and seedling ecology on Barro Colorado Island  a field station in the Panama Canal. This work led to the discovery that fungi are a major determinant of seed survival in the soil. His current research explores plant-mycorrhizal effects on species distributions in montane forests  the assembly of communities of wood decay fungi in terrestrial and aquatic habitats  and the host-specificity and demographic impact of seed-infecting fungi. His seed work has led to the discovery that fungi can have both mutualistic and pathogenic effects on seeds  depending on the host species they infect.    \nThis lecture was recorded and is viewable to active members who are logged in.
