Regulation of endosymbioses by CEP and CLE signaling peptides in Medicago truncatula On the left (green background), regulation of nitrogen-fixing nodulation by signaling peptides in Medicago truncatula. On the right (orange background), regulation of mycorrhization by signaling peptides in M. truncatula.

Have a look to the new review from the F. Frugier’s SILEG team @IPS2ParisSaclay, published in Trends in Plant Sciences, about signaling peptides acting at the crossroad of plant root endosymbioses. #PlantSciences ips2.u-psud.fr/en/articles/...

Simplified model of Enterobacter sp. SA187 impact on Arabidopsis thaliana under low N conditions SA187 inoculation promotes plant growth under low nitrate by modulating the expression of high-affinity nitrate transporters (HATS) through both ethylene-dependent and independent pathways. NRT2.5 is strongly upregulated in presence of SA187 in an EIN2-dependent manner in both shoots and roots, while NRT2.6 shows tissue-specific regulation: downregulated in shoots, and upregulated in roots, with a partial ethylene independence.

Have a look to the new @IPS2 study from Ilyas et al. on a beneficial bacterium that improves plant growth in low fertilization conditions #PlantScience ips2.u-psud.fr/en/articles/...

Model describing the role of LD in transcription regulation A. A complex comprising LD is recruited to transcription sites thanks to its ability to interact with the MED18 subunit of the Mediator complex. RNA Pol II dephosphorylation decreases the transcription rate. B. Hypothesis concerning the role of LD during replication stress: after detecting collisions between the replication and transcription machinery, the recruitment of LD may enable the inhibition of transcription, the resolution of the transcription/replication conflict, and the replication fork restart

Plants establish beneficial interactions with both fungi and bacterial microbes that they attract from the soil rhizosphere by producing signalling molecules under conditions of nutritional deficiency. (A) arbuscular mycorrhizal (AM) symbiosis, (B) nitrogen-fixing rhizobial nodulation symbiosis, (C) other beneficial plant-fungi interactions, such as the ectomycorrhizal symbiosis (ECM) and the association with Trichoderma or Mucoromycotina ‘fine root endophytes’ (MFRE), (D) interactions with Plant Growth-Promoting Rhizobacteria (PGPR) Figure generated using BioRender (https://biorender.com/).

Cytosolic Monodehydroascorbate Reductase 2 Promotes Oxidative Stress Signaling in Arabidopsis Much remains to be discovered about how the complex plant antioxidant network interacts to determine the outcome of oxidative stress, a central factor in plant responses to the environment. This work...

I am very happy to share an article in Plant Cell & Environment interested in the roles of MDHAR in oxidative stress in #Arabidopsis. The role of the cytosolic MDAR2 is particularly intriguing. To know more: onlinelibrary.wiley.com/doi/full/10.... 1/2
