    Competence for transcellular infection in the root cortex involves a post-replicative, cell-cycle exit decision in Medicago truncatula

    Competence for transcellular infection in the root cortex involves a post-replicative, cell-cycle exit decision in Medicago truncatula by Morgane Batzenschlager, Beatrice Lace, Ning Zhang, Chao Su, Anna Boiger, Sabrina Egli, Pascal Krohn, Jule Salfeld, Franck Anicet Ditengou, Thomas Laux, Thomas Ott

    Published 2025-07-01

    During root nodule symbiosis (RNS), cell-division activity is reinitiated and sustained in the root cortex to create a hospitable cellular niche. Such a temporary and spatially confined site is required to render host cells compatible with the intracellular progression of rhizobia. Although it has b...

    Published 2025-01-01

    The geometric distances of active galactic nuclei (AGNs) are challenging to measure because of their exceptionally compact structure, yet vast cosmic distances. A combination of spectroastrometry and reverberation mapping (SARM) of broad-line regions (BLRs) constitutes a novel means to probe the geo...
