Sequences from: Enhanced climate tolerance for trees derived from microbial communities
Changing climates are pushing species outside of evolved tolerances; populations must acclimate, adapt, or migrate to avoid extinction. However, because plants associate with diverse microbial communities that shape their phenotype, shifts in microbial associations may provide an alternative source of novel climate tolerance. Here we show that tree seedlings inoculated with microbial communities sourced from drier, warmer, or colder sites displayed higher survival when facing drought, heat, or cold stress, respectively. Microbially mediated drought tolerance was associated with increased diversity of arbuscular mycorrhizal fungi, while cold tolerance was associated with lower fungal richness, likely reflecting a reduced burden of non-adapted fungal taxa. Understanding microbially mediated climate tolerance may enhance our ability to predict and manage the adaptability of forest ecosystems to changing climates.This submission represents the fungal ITS2 sequences used to derive the conclusions above.
