CC-NLRs exhibit diverse conformations in the resting state. Figure depicts different NLR resting and activated states. While ZAR1 exists as a monomer bound to its guardees in its resting state, several forms have been observed for the NRC2 helper, including dimers, tetramers, and filaments. While filament-like structures were observed via confocal microscopy for NRC2 upon overexpression in planta, these structures were not detected for its paralog NRC4, suggesting a potentially different resting state configuration for NRC4. Our work suggests that the Pik CC-NLR pair forms a hetero-complex bound to the plasma membrane in its resting state. How effector binding to the integrated domain (ID) of the Pik-1 sensor leads to the activation of the complex remains to be determined.

Autophagy restricts symbiosis-associated cell death and regulates colonization by Serendipita indica in Arabidopsis Autophagy acts as a pro-survival mechanism in plant roots during beneficial fungal colonization by restricting fungal proliferation and immunometabolic cel

My former colleague Patricia Zecua, me and the Zuccaro group published a new story about how autophagy restricts cell death and regulates root colonization by beneficial fungi:

Fig. 1 (shortened, full legend in paper): CSEP0162 interacts with the C-terminus, but not ‘full-length’ HvMON1 in Y2H. The yeast strain Y8930 was transformed with constructs fusing either CSEP0162, CSEP0105, or HvCCZ1 with the GAL4 DNA-binding-domain (BD) (pDEST-AS2-1 vector, cloned from respective pENTR clones using Gateway LR cloning). The yeast strain Y8800 was transformed with either empty vector pDEST-ACT2, or constructs fusing either amino acids 22–598 of HvMON1 or the C-terminus (amino acids 539–598) of HvMON1 with the activation domain (AD) (pDEST-ACT2 vector, cloned from the respective pENTR clones using Gateway LR cloning). Transformed strains were mated in the listed combinations and plated on dropout (DO) medium lacking leucine (L) and tryptophan (W). Drop test was performed by adjusting cultures to OD600 = 1.0 (100), and with further serial dilutions (10–1 and 10–2). Growth on these plates indicates the presence of both constructs.

Two residues reprogram immunity receptors for nitrogen-fixing symbiosis Receptor signalling determines cellular responses and is crucial for defining specific biological outcomes. In legume root cells, highly similar and structurally conserved chitin and Nod factor receptor kinases activate immune or symbiotic pathways, respectively, when chitinous ligands are perceived1. Here we show that specific amino acid residues in the intracellular part of the Nod factor receptor NFR1 control signalling specificity and enable the distinction of immune and symbiotic responses. Functional investigation of CERK6, NFR1 and receptor variants thereof revealed a conserved motif that we term Symbiosis Determinant 1 in the juxtamembrane region of the kinase domain, which is key for symbiotic signalling. We show that two residues in Symbiosis Determinant 1 are indispensable hallmarks of NFR1-type receptors and are sufficient to convert Lotus CERK6 and barley RLK4 kinase outputs to enable symbiotic signalling in Lotus japonicus.

Very nice work -> Two residues reprogram immunity receptors for nitrogen-fixing symbiosis

Symbiotic diversification relies on an ancestral gene network in plants | bioRxiv Symbioses have been fundamental to colonization of terrestrial ecosystems by plants and their evolution. Emergence of the ancient arbuscular mycorrhizal symbiosis was followed by the diversification of alternative intracellular symbioses, such as the ericoid mycorrhizae (ErM). We aimed at understanding how these diversifications occurred. We sequenced the genomes of ErM-forming liverworts, and reconstituted symbiosis under laboratory conditions. We demonstrated the existence of a nutrient-regulated symbiotic state that enables ErM and underlies intracellular colonization of plant tissues. Comparative transcriptomic analyses identified an ancestral gene module associated with intracellular symbiosis beyond ErM. Genetic manipulations in the liverwort Marchantia paleacea, phylogenetics and transactivation assays demonstrated its essential function for intracellular symbiosis. We conclude that plant have maintained, and convergently recruited, an ancestral gene module for intracellular symbioses.
