Crop breeding aims to balance disease resistance with yield, however single resistance (R) genes can lead to resistance breakdown and R gene pyramiding may impact growth fitness. Here we report that the rice Pigm locus contains a cluster of genes encoding nucleotide-binding leucine-rich repeat (NLR) receptors that confer durable resistance to the fungus Magnaporthe oryzae without yield penalty. ...
