    Poplar (Populus trichocarpa and P. deltoides) grow in the Advanced Plant Phenotyping Laboratory (APPL) at Oak Ridge National Laboratory in Tennessee. Poplar is an important biofuel feedstock, and Populus trichocarpa is the first tree species to have its genome sequenced — a feat accomplished by JGI.

Fungal Evolution of Truffle-Like Bodies

The reproductive success of fungi is heavily influenced by climate. For those fungi that produce emergent mushroom-like fruit bodies, periods of drought or heat can severely curtail the spread of these fungi within an ecosystem due to rapid drying of the developing hymenium thus limiting spore production and dispersal. Some fungi have evolved the adaptation of producing truffle-like fruit bodies (below ground or emergent, with an enclosed spore mass) – likely in response to past extreme climatic events. This project aims to determine the molecular pathway(s) that led to the evolution of truffle-like fungal fruit bodies within globally diverse lineages of mushroom-like basidiomycete ectomycorrhizal (ECM) and saprotrophic fungi as a response to previous events of climatic extremes and change. These data will enable new avenues of research into the ecology of truffle-like fungi and will eventually further work into understanding the microbiome of forest trees.
