‘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.

HIGH INFECTION PRESSURE OF ESFY PHYTOPLASMA THREATENS THE CULTIVATION OF STONE FRUIT SPECIES [PDF]

Journal of Central European Agriculture, 2009
Stone fruit species are affected by severe disease caused by European stone fruit yellows phytoplasma (ESFY; ‘Candidatus Phytoplasma prunorum’). ESFY phytoplasma is transmitted to the host plants of Prunus spp. by the vector Cacopsylla pruni. The disease

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, Volume 24, Issue 5, Page 2939-2955, May 2026.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

‘Candidatus Liberibacter Asiaticus’ Effector SECP8 Subverts Salicylic Acid‐Mediated Citrus Immunity via a Two‐Pronged Impairment of CsTCP15 Dimerization

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2335-2349, April 2026.
ABSTRACT Citrus Huanglongbing (HLB), a devastating disease caused by the unculturable bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), poses a severe threat to global citrus production. CLas secretes effectors to suppress host immune responses and facilitate its colonisation. Previously, the CLas effector SECP8 (CLIBASIA_05330) has been identified

Differential Symptomology, Susceptibility, and Titer Dynamics Manifested by Phytoplasma-Infected Periwinkle and Tomato Plants

Plants
Phytoplasmas are intracellular pathogenic bacteria that infect a wide range of plant species, including agriculturally important crops and ornamental trees. However, our understanding of the relationship between symptom severity, disease progression, and

Cytopathological evidence for transport of phytoplasma in infected plants

Acta Societatis Botanicorum Poloniae, 2014
Pleomorphic phytoplasmas were observed in sieve tubes, companion cells and in phloem parenchyma of Tagetes patula L., Helichrysum bracteatum Willd. and Gladiolus sp. L. plants with morphological changes typical for phytoplasma infection.
