Data from: Mycelia-derived C contributes more to nitrogen cycling than root-derived C in ectomycorrhizal alpine forests

Ziliang Zhang, Richard P. Phillips, Wenqiang Zhao, Yuanshuang Yuan, Qing Liu & Huajun Yin
1. Plant roots and their associated microbial symbionts impact carbon (C) and nutrient cycling in ecosystems, but estimates of the relative contributions of root- versus microbe-derived dynamic inputs are highly uncertain. Roots release C into soil via exudation and turnover (i.e., root-derived C), but also by allocating C to mycorrhizal fungal mycelia, which exude C and undergo turnover (i.e., mycelia-derived C). Given that the relative contributions of root- and mycelia-derived C inputs are unknown, a...

Nodules harboring nitrogen-fixing rhizobia are a well-known trait of legumes, but nodules also occur in other plant lineages, with rhizobia or the actinomycete Frankia as microsymbiont. It is generally assumed that nodulation evolved independently multiple times. However, molecular-genetic support for this hypothesis is lacking, as the genetic changes underlying nodule evolution remain elusive. We conducted genetic and comparative genomics studies by using Parasponia species (Cannabaceae), the only nonlegumes that can establish nitrogen-fixing nodules with rhizobium....

Human societies depend on an Earth System that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N concentrations ([N]) and isotope ratios (15N) from more than 42,000 samples acquired over 37 years, here we show that foliar [N] declined by 8% and foliar 15N declined by 0.8 – 1.9 ‰. Examining patterns across different climate spaces, foliar 15N declined across...
