Targeting the “bitterness gene” by genome editing abolishes synthesis of bitter flavanones in citrus; prospects for new varieties and extended climates for cultivation Open
SUMMARY Bitterness in citrus fruit is conferred by flavanone‐neohesperidosides, whose accumulation is catalyzed by a single enzyme flavanone‐7‐ O ‐glucosides‐1,2‐rhamnosyltransferase (1,2RhaT), expressed in both leaves and fruit. To elimin…
