NONEXPRESSOR OF PATHOGENESIS-RELATED GENES control Huanglongbing tolerance by regulating immune balance in citrus plants

Poulami Sarkar, Choaa Amine El-Mohtar, Chunxia Wang…·Amit Levy

This study shows that overexpressing AtNPR1 or silencing AtNPR3/AtNPR4 orthologs in citrus enhances HLB tolerance by regulating immune balance and reducing callose and ROS accumulation.
