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

P. Sarkar, C. El-Mohtar, D. Turner, S. Welker, C. J. Robertson, V. Orbovic, Z. Mou, A. 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.

Candidatus Liberibacter asiaticus reduces callose and reactive oxygen species production in the phloem

C. Bernardini, D. Turner, C. Wang, S. Welker, D. Achor, Y. Acanda, R. Turgeon, A. Levy

This study shows that Candidatus Liberibacter asiaticus reduces callose and reactive oxygen species in the phloem, suggesting it manipulates host metabolism to evade defenses.

Phloem transport limitation in Huanglongbing affected sweet orange is dependent on phloem-limited bacteria and callose

S. Welker, M. Pierre, J. P. Santiago, M. Dutt, C. Vincent, A. Levy

This study shows that callose accumulation and CLas infection interact to limit phloem transport in HLB-affected sweet orange, with rootstock genotype modulating the extent of this limitation.
