Excited to share this new Tansley article from our lab! We discuss how plants differentiate between different microsymbionts to ensure beneficial symbiosis outcomes, comparing nodulation and AM symbiosis. @newphyt.bsky.social

it was great to collaborate with @lmueller.bsky.social to help characterize the Medicago crn mutant!

🌱 EDITOR'S CHOICE 🌱 Plant interactions with beneficial AM fungi are regulated by complex signaling pathways. The pseudokinase CORYNE negatively regulates the symbiosis by integrating plant responses to multiple abiotic and biotic cues - Orosz et al. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Fig. 1 (shortened, full legend in paper): Medicago truncatula CRN impacts inflorescence development. (A) Close-up of R108 wild-type flower. One hundred percent of inflorescences produced a solitary flower in our growth conditions. (B) Dissected wild-type flower. Std, standard petal; fused keel and two wing petals; c+s, carpel and stamen. (C) Close-up of inflorescence produced by crn. Note the additional undeveloped bud (arrowhead). In our growth conditions, 91% of crn mutants produced two flowers per inflorescence; the remaining 9% produced solitary flowers similar to the one shown in (A). (D) Dissected crn flower. Flower organ number and morphology appeared similar to the R108 wild type shown in (B). (A–D) Scale bars: 0.5 mm. (E) Scanning electron microscopy images of R108 and crn inflorescence apices. In M. truncatula, the primary inflorescence meristem (I1) produces a secondary inflorescence meristem (I2) and leaf primordium (L).

Great review from @lmueller.bsky.social -> Signaling peptides control beneficial and pathogenic plant-microbe interactions | Journal of Experimental Botany | Oxford Academic

Signaling peptides control beneficial and pathogenic plant-microbe interactions

Interactions between organisms, such as those between plants and microbes, require extensive signaling between and within each organism to detect and recognize the partner and elicit an appropriate response. Multiple families of small signaling peptides regulate plant interactions with beneficial or pathogenic microbes, and sometimes both. Some of these signaling peptides transmit information between different cells or organs of the host and allow plants to orchestrate a coordinated response towards microbial mutualists or pathogens. However, not only plants produce signaling peptides required for the interactions. Microbes themselves also secrete peptide signals, which are detected by host receptors and required for infection. Among these are microbial peptides mimicking those of plants, allowing mutualistic or pathogenic microbes to hijack endogenous plant signaling pathways and evade the host immune system. In this review, we provide a comprehensive summary of current knowledge on host- and microbe-derived signaling peptides and their cognate receptors regulating mutualistic and parasitic plant-microbe interactions. Furthermore, we describe how microbes hijack endogenous host signaling pathways, and discuss possible crosstalk between the plant signaling pathways controlling mutualism with those modulating immune responses to pathogens.

Proud to present the first data paper from the lab, published today in @pnas.org. We describe a new mechanism for CLE peptides as local symbiosis-amplifying signals, promoting plant interactions with beneficial arbuscular mycorrhizal fungi. Congratulations @sagarbashyal.bsky.social et al.!

Matt Salomon and I just published a commentary on @lizkoziol.bsky.social’s recent paper in New Phyt on AMF products. These products are lacking - but whose responsibility is it to further their quality and function for agriculture - academia or industry? nph.onlinelibrary.wiley.com/doi/10.1111/...
