BACKGROUND Microbial interactions have shaped plant diversity in terrestrial ecosystems.
By forming mutually beneficial symbioses, microbes helped plants colonize land more than …

This is the opening paper in the special issue of Fungal Diversity, which collates the data on
defining species. Defining and recognizing species has long been a controversial issue …

BACKGROUND Although plants are dependent on the capture of a number of elemental
nutrients from the soil, the principal nutrients that limit plant productivity are nitrogen (N) and …

Testing of ecological, biogeographical and phylogenetic hypotheses of mycorrhizal traits
requires a comprehensive reference dataset about plant mycorrhizal associations. Here we …

Ferns are the closest sister group to all seed plants, yet little is known about their genomes
other than that they are generally colossal. Here, we report on the genomes of Azolla …

Plant roots exhibit diverse root functional traits to enable soil phosphorus (P) acquisition,
including changes in root morphology, root exudation and mycorrhizal symbioses. Yet …

Hornworts comprise a bryophyte lineage that diverged from other extant land plants> 400
million years ago and bears unique biological features, including a distinct sporophyte …

INTRODUCTION Access to nutrients such as nitrogen is required for plant growth. Legumes
and nine additional plant families benefit from the nitrogen-fixing root nodule (NFN) …

Arbuscular mycorrhiza (AM) symbioses contribute to global carbon cycles as plant hosts
divert up to 20% of photosynthate to the obligate biotrophic fungi. Previous studies …

BACKGROUND Among the extensive cortège of plant-associated microorganisms (the so-
called plant microbiota), mutualistic fungal and bacterial symbionts are striking examples of …
