When Does Fungicide Use Pay Off in Maize? Evidence From Low Foliar Disease Pressure Environments in Southern Brazil

open access: yesJournal of Phytopathology, Volume 174, Issue 3, May/June 2026.
ABSTRACT Foliar fungicides are widely used in maize production in southern Brazil, yet their economic justification under low disease pressure remains uncertain. We synthesised yield and economic responses to a fungicide programme using a random‐effects meta‐analytic approach based on 19 multi‐environment trials conducted across the first and second ...

Global Status of Phytoplasma Diseases in Vegetable Crops

open access: yesFrontiers in Microbiology, 2019
The presence of phytoplasmas and their associated diseases is an emerging threat to vegetable production which leads to severe yield losses worldwide. Phytoplasmas are phloem-limited pleomorphic bacteria lacking the cell wall, mainly transmitted through ...

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

open access: yesMolecular 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.

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

open access: yesPlant 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.

Distribution of Phytoplasmas in Infected Plants as Revealed by Real-Time PCR and Bioimaging

open access: yesMolecular Plant-Microbe Interactions, 2004
Phytoplasmas are cell wall-less bacteria inhabiting the phloem and utilizing it for their spread. Infected plants often show changes in growth pattern and a reduced crop yield.
