Abstract
Knocking out three susceptibility genes (Pi21, Bsr-d1, and Xa5) in a rice breeding line that contains the resistance Piz-t produced enhanced broad-spectrum resistance against the fungal pathogen Magnaporthe oryzae and the bacterial pathogen Xanthomonas oryzae pv. oryzae without obvious growth penalty.
