The Arabidopsis thaliana pan-NLRome

A.-L. Van de Weyer, F. Monteiro, O. J. Furzer, M. T. Nishimura, V. Cevik, K. Witek, J. D. G. Jones, J. L. Dangl, D. Weigel, F. Bemm

The paper defines the Arabidopsis thaliana pan-NLRome by analyzing NLR diversity across 65 accessions, finding that 40 accessions saturate the NLRome and identifying architectural diversity and selective forces.
