First Detection of Eutypella parasitica in Western North America: Novel Host Records From Asymptomatic Acer macrophyllum and A. circinatum

Forest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT Eutypella parasitica, causal agent of Eutypella canker of maple, is native to eastern North America and has been introduced into Europe, where it affects several Acer species. During an unrelated pathogenicity experiment, E. parasitica was unexpectedly isolated from asymptomatic bigleaf maple (Acer macrophyllum) and vine maple (A.

Dieback of Eucalypt Mini‐Stumps Caused by Chrysoporthe Species.: Pathogen Detection in Symptomatic and Asymptomatic Host and Pathogen Transmission in Mini‐Clonal Hedge

Forest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT The fungus Chrysoporthe cubensis has been reported to cause significant losses in eucalypt mini‐clonal hedge systems in Brazil, where the disease is characterized by wilting, xylem lesion and dieback of mini‐stump. This study aimed to investigate the occurrence of Chrysoporthe species occupying an endophytic niche in asymptomatic mini‐stumps ...

‘Candidatus Liberibacter asiaticus’ secretory protein SDE5640 activates host autophagy dependent on PSMD10 to mediate PBA1 degradation

The Plant Journal, Volume 128, Issue 1, October 2026.
Significance Statement In healthy citrus cells, CsPSMD10 directly binds CsATG8 and targets it for ubiquitin‐dependent degradation by the intact 26S proteasome, maintaining low free CsATG8 levels and suppressing autophagy to preserve immune homeostasis.

CsGATA5‐CsTRYS/CsTDC2 module coordinates tryptophan‐mediated wound healing in postharvest citrus fruit

The Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY The wound healing process in postharvest citrus fruit represents a crucial physiological mechanism that effectively resists external stress and minimizes quality deterioration. Nevertheless, the molecular mechanisms involved in wound healing by GATA transcription factors in citrus remain largely unexplored.
