Pervasive RNA Regulation of Metabolism Enhances the Root Colonization Ability of Nitrogen-Fixing Symbiotic α-Rhizobia [PDF]
mBio, 2022 The rhizosphere and rhizoplane are nutrient-rich but selective environments for the root microbiome. Here, we deciphered a posttranscriptional network regulated by the homologous trans-small RNAs (sRNAs) AbcR1 and AbcR2, which rewire the metabolism of ...

The role of nutritional impairment in carbon-water balance of silver fir drought-induced dieback. [PDF]
Glob Chang Biol, 2022 Declining silver fir trees show lower foliar concentrations of essential nutrients such as P, K, Cu and Ni than non‐declining trees. This nutritional impairment exacerbates and amplifies the negative effects of drought on tree functioning and growth, considering the relationship of tree nutritional status with water‐use efficiency and growth resilience

Riboregulation in Nitrogen-Fixing Endosymbiotic Bacteria [PDF]
Microorganisms, 2020 Small non-coding RNAs (sRNAs) are ubiquitous components of bacterial adaptive regulatory networks underlying stress responses and chronic intracellular infection of eukaryotic hosts. Thus, sRNA-mediated regulation of gene expression is expected to play a

Soil nitrogen dynamics after Brachiaria desiccation
Revista Brasileira de Ciência do Solo, 2013 Brachiaria species, particularly B. humidicola, can synthesize and release compounds from their roots that inhibit nitrification, which can lead to changes in soil nitrogen (N) dynamics, mainly in N-poor soils.
