Generation of novel bpm6 and dmr6 mutants with broad‐spectrum resistance using a modified CRISPR/Cas9 system in Brassica oleracea

Using an optimized CRISPR/Cas9 system to knock out the BTB-POZ and MATH domain gene BoBPM6 and the DOWNY MILDEW RESISTANCE 6 gene in Brassica oleracea resulted in new lines with broad-spectrum disease resistance.
