In California's Changing Climate, Latent Pathogens Drive Novel Woody Plant Diebacks on a Large Geographic Scale

Plant Pathology, Volume 74, Issue 9, Page 2697-2714, December 2025.
Novel plant diebacks are emerging in association with reoccurring droughts in California. Field isolations and greenhouse trials show that latent pathogens and drought together, and not drought alone, cause the most severe diebacks. ABSTRACT The detection of emergent biotic and abiotic threats to plant health is challenging in an interconnected world ...

An Apple Susceptibility‐Related LRR Receptor‐Like Kinase MdRLKT21 Activates Plant Immunity by Hijacking a Trans‐Kingdom Fungal microRNA‐Like RNA

Advanced Science, Volume 12, Issue 38, October 13, 2025.
The apple susceptibility‐related LRR‐RLK MdRLKT21 competitively binds to fungal sRNA effectors and subsequently activates defenses by salvaging the expression of MdRLKT1 and MdRLKT2 and thereby releasing the resistance protein MdRFP1. These findings provide new insights into the molecular mechanism by which plants counteract pathogen‐secreted sRNA ...

Testing for the Presence of Botryosphaeria dothidea in Ceanothus spinosus

, 2017
Botryosphaeria dothidea is an opportunistic fungus found in some of the cavitated branches of the vegetation in the Santa Monica Mountains. In this study, we focused on finding the presence of Botryosphaeria dothidea in Ceanothus spinosus located on ...

Botryosphaeria species associated with diseases of grapevines in Portugal

Phytopathologia Mediterranea, 2002
Although Botryosphaeria species are known to cause cankers and dieback in many different woody hosts, their importance in grapevines has been largely ignored. Indeed, they are more often regarded as saprophytes or weak pathogens.

Class III endophytes, clandestine movement amongst hosts and habitats and their potential for disease; a focus on Neofusicoccum australe

, 2011
Neofusicoccum australe is a class III endophyte characterised by a quiescent passive life phase and an active pathogenic life phase as a latent pathogen. The latter life stage has been observed worldwide for numerous woody horticultural hosts.

Drought heightens severity of diseases caused by Botryosphaeria dothidea and Cryptostroma corticale and needs to be factored in to properly assess pathogenicity or fulfill Koch’s postulates

Journal of plant pathology
Climate change is driving the emergence of novel tree diseases at the global scale, requiring new approaches for the formal confirmation of the pathogenicity of novel pathogens on novel hosts.
