Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

The Common Bean miR172c microRNA, a Relevant Regulator of the N-Fixing Symbiosis, Is Activated by SPL and AGL/MADS-Domain Transcription Factors. [PDF]

Physiol Plant
ABSTRACT Nitrogen‐fixing symbiosis (NFS) between rhizobia and legume plants is a complex and tightly regulated process. Modules of microRNAs (miRNAs) and their targets from different legumes, such as miR156‐SPL and miR172‐AP2‐1, form part of complex cascades relevant for the regulation of NFS.
