The transcription factor SiROCX controls a monocot-specific CAZyme program for host cell wall remodeling during symbiotic root colonization

This study identifies SiROCX as a transcription factor regulating a monocot-specific CAZyme program for host cell wall remodeling during fungal symbiosis.

A fungal root endophyte functionally complements host immunity and mitigates natural immune variation in Arabidopsis

This study shows that the fungal endophyte Serendipita indica reduces disease susceptibility in Arabidopsis regardless of host genotype and that the immune receptor ISI contributes to root immunity but is not required for endophyte protection.

Host-adapted enzymatic deconstruction of acetylated xylan enables mutualistic colonization of monocot roots

This paper identifies a host-adapted enzymatic module in Serendipita indica that degrades acetylated xylan in monocot roots, enabling fungal colonization while suppressing immune responses.
