From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees

Biological Reviews, Volume 101, Issue 1, Page 314-335, February 2026.
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

Functional genomics of a symbiotic community : shared traits in the olive fruit fly gut microbiota [PDF]

, 2019
The olive fruit fly Bactrocera oleae is a major pest of olives worldwide and houses a specialized gut microbiota dominated by the obligate symbiont “Candidatus Erwinia dacicola”. Ca. E. dacicola is thought to supplement dietary nitrogen to the host, with

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

Advanced Science, Volume 13, Issue 3, 14 January 2026.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

Hexuronate catabolism in Erwinia chrysanthemi [PDF]

Journal of Bacteriology, 1987
In the phytopathogenic enterobacterium Erwinia chrysanthemi, the catabolism of hexuronates is linked to the degradation of pectic polymers. We isolated Mu lac insertions in each gene of the hexuronate pathway and used genetic fusions with lacZ (the beta-galactosidase gene of Escherichia coli) to study the regulation of this pathway.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, Volume 13, Issue 1, 5 January 2026.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Identification of bacterial endophytes from champa rice cultivar and study of their effects on growth properties of host plant [PDF]

مجله بیوتکنولوژی کشاورزی, 2017
Endophytes are symbiont microorganisms within apoplast or symplast of plants that promote growth, control phytopathogens, increase plant resistance to stress and improve plant growth conditions. The aim of this study was identification of endophytes from

Fire blight in different production systems in Germany and strategies to control the disease [PDF]

, 2004
Fire blight, caused by the bacterium Erwinia amylovora, is a serious disease of pome fruits in many countries of the world. The disease was first recognized at the end of the 18th century in the USA.
