Symbiosome functionality in Medicago truncatula nodules requires continuous clearing of pectins from the symbiosome space - Nature Communications Here a mechanism for nitrogen fixation maintenance is identified in Medicago truncatula where two polygalacturoneases are expressed in nodules and secreted into the symbiosome space for clearing of ex...

Happy to share our latest paper: The symbiosome space needs to be continuously cleared from demethylated pectins to keep rhizobia happy. Former PostDoc Chao Su took this story with him when moving back to China and finished it off.

RSD‐mediated suppression of NIN and NLP2 transcription is crucial for symbiotic nitrogen fixation Indeterminate nodules establish a developmental gradient along their longitudinal axis, separating cell differentiation from symbiotic nitrogen fixation (SNF). The apex contains differentiating cell...

Glad to share the latest research from my PhD lab !!
RSD interacts with NIN and NLP2 to control cell fate in root nodules, serving as a switch between symbiont differentiation and nitrogen fixation.
