‘Candidatus Liberibacter asiaticus’ Effector SDE4250 Targets Citrus Proteasome Protein RPN10 to Inhibit Salicylic Acid‐Mediated Citrus Immunity

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
SDE4250 suppressed 26S proteasome activity by targeting CsRPN10 and enhancing its degradation via the proteasome pathway. This impairment of proteasome function subsequently attenuates SA‐mediated defence responses, thereby increasing citrus susceptibility to promote CLas infection.

Molecular diagnosis of phytoplasmas.

Phytopathologia Mediterranea, 2003
Phytoplasmas are wall-less prokaryotes associated with diseases in numerous plant species worldwide. In nature they are transmitted by phloem-sucking insects. Yellowing, decline, witches’ broom, leaf curl, floral virescence and phyllody are the most conspicuous symptoms associated with phytoplasmas, although infections are sometimes asymptomatic. Since
