Oligomerisation of a plant helper NLR requires cell-surface and intracellular immune receptor activation

J. M. Feehan, J. Wang, X. Sun, J. Choi, H.-K. Ahn, B. P. M. Ngou, J. E. Parker, J. D. Jones

This study shows that helper NLR NRG1 forms oligomeric complexes with EDS1 and SAG101 at the plasma membrane upon co-activation of intracellular and cell surface receptors.

Effector-dependent activation and oligomerization of NRC helper NLRs by Rpi-amr3 and Rpi-amr1

H.-K. Ahn, X. Lin, A. C. Olave-Achury, L. Derevnina, M. P. Contreras, J. Kourelis, S. Kamoun, J. D. Jones

This study shows that sensor NLRs Rpi-amr3 and Rpi-amr1 activate the helper NLR NRC2 to form a resistosome in response to Phytophthora effectors.

Sensor NLR immune proteins activate oligomerization of their NRC helper

M. P. Contreras, H. Pai, Y. Tumtas, C. Duggan, E. L. H. Yuen, A. Vergara Cruces, J. Kourelis, H.-K. Ahn, C.-H. Wu, T. O. Bozkurt, L. Derevnina, S. Kamoun

The paper shows that activation of plant NLRs Rx and Bs2 leads to oligomerization of the helper NLR NRC2, suggesting a distinct activation model compared to mammalian paired NLRs.

Mutual Potentiation of Plant Immunity by Cell-surface and Intracellular Receptors

B. P. M. Ngou, H.-K. Ahn, P. Ding, J. D. Jones

This study shows that plant immune pathways activated by cell-surface and intracellular receptors mutually enhance each other to provide effective resistance against pathogens.

Estradiol-inducible AvrRps4 expression reveals distinct properties of TIR-NLR-mediated effector-triggered immunity

B. P. M. Ngou, H.-K. Ahn, P. Ding, A. Redkar, H. Brown, Y. Ma, M. Youles, L. Tomlinson, J. D. Jones

The paper induces AvrRps4 expression in Arabidopsis to study RRS1/RPS4-mediated immunity without pathogen presence, revealing downstream immune responses.
