TL;DR: Analysis of the mucilage microbiota of an indigenous landrace of maize grown in nitrogen-depleted soils in the Sierra Mixe region of Oaxaca, Mexico indicated that it was enriched in taxa for which many known species are diazotrophic, was enriched for homologs of genes encoding nitrogenase subunits, and harbored active nitrogenase activity.

TL;DR: Deep untargeted tandem mass spectrometry-based measurements of rapid NF-induced changes in the phosphorylation status of 13,506 phosphosites in 7739 proteins from the model legume Medicago truncatula suggest “cryptic” NF-signaling pathways, some of them being also involved in the response to symbiotic arbuscular mycorrhizal fungi.

TL;DR: It is demonstrated that HMGR1 is required to initiate Ca2+ spiking and symbiotic gene expression in Medicago truncatula roots in response to rhizobial and arbuscular mycorrhizal fungal signals and that the nuclear cation channel DMI1 is sufficient to support MVA-induced Ca2 + spiking in this heterologous system.

TL;DR: A quantitative proteomic atlas of the model legume Medicago truncatula and its rhizobial symbiont Sinorhizobium meliloti is described, which includes more than 23,000 proteins, 20,000 phosphorylation sites, and 700 lysine acetylation sites, which provides insight into mechanisms regulating symbiosis.

TL;DR: It is shown that Lipo-chitooligosaccharides are produced also by many other, non-symbiotic fungi, and regulate fungal growth and development, and LCOs may function as signals regulating fungalgrowth and development.
