Plants can form an immunological memory known as defense priming, whereby exposure to a priming stimulus enables quicker or stronger response to subsequent attack by pests and pathogens. Such priming of inducible defenses provides increased protection and reduces allocation costs of defense. Defense priming has been widely studied for short-lived model plants such as Arabidopsis, but little is known about this phenomenon in long-lived plants like spruce. We compared the effects of pre-treatment…

Molecular underpinnings of methyl jasmonate-induced resistance in Norway spruce.
The most detailed insights yet are provided into the mechanisms underlying induced resistance in a long-lived gymnosperm, suggesting that priming of inducible defenses is part of a complex mixture of defense responses that underpins the increased resistance against bark beetle colonization observed in Norway spruce.
Variation in Methyl Jasmonate-Induced Defense Among Norway Spruce Clones and Trade-Offs in Resistance Against a Fungal and an Insect Pest
It is found that MeJA treatment increased resistance to H. abietis and E. polonica, but the extent of protection will depend on the importance of constitutive and induced resistance for the Norway spruce clone in question, and variation in chemistry was mostly explained by differences between clones.
Bark Beetle Attack History Does Not Influence the Induction of Terpene and Phenolic Defenses in Mature Norway Spruce (Picea abies) Trees by the Bark Beetle-Associated Fungus Endoconidiophora polonica
Terpenes and phenolics are important constitutive and inducible conifer defenses against bark beetles and their associated fungi. In this study, the inducible defenses of mature Norway spruce (Picea
Primary and secondary host selection by Ips typographus depends on Norway spruce crown characteristics and phenolic-based defenses.
A Battle for the Forest: Spruce Castles and Bark Beetle Attacks
It is found that spraying spruce trees with a natural chemical, called methyl jasmonate, can boost tree defenses and protect the trees against a bark beetle attack.
What Happens to Wood after a Tree Is Attacked by a Bark Beetle?
Wood-decay fungi that colonize wood after infestation of a tree with bark beetles can cause significant changes in the structure and properties of the wood, and these changes are predominantly negative, in the form of reducing moduli of rupture, modulus of elasticity, discolouration, or, over time, weight loss.
Pathophysiology and transcriptomic analysis of Picea koraiensis inoculated by bark beetle-vectored fungus Ophiostoma bicolor
This study showed that O. bicolor was a weakly virulent pathogen of spruce, and that the virulent of the five O. Bicolor strains showed differentiation; and a positive correlation between fungal virulence and release of monoterpenoids was observed.
Seasonal timing and recurrence of methyl jasmonate treatment influence pine weevil damage to Norway spruce seedlings
It is indicated that MJ can be applied in line with nursery practices (before winter storage) and provides adequate protection for two growing seasons and this reduction in damage was comparable to that provided by a currently used physical protection method against pine weevil feeding.
Chemical signal interactions of the bark beetle with fungal symbionts, and host/non-host trees
It is put forward a hypothesis that host plants are ecological and evolutionary determinants of bark beetle-fungus symbioses in terms of their complex signaling interactions and convergence and mutualism patterns in the evolution of I. subelongatus and E. fujiensis with respect to host tree volatiles.


Inducibility of chemical defenses in Norway spruce bark is correlated with unsuccessful mass attacks by the spruce bark beetle
The results show that the potential of individual P. abies trees for inducing defense compounds upon I. typographus attack may partly determine tree resistance to this bark beetle by inhibiting its mass attack.
Exogenous application of methyl jasmonate elicits defenses in Norway spruce (Picea abies) and reduces host colonization by the bark beetle Ips typographus
The terpenoid and phenolic constituents of conifers have been implicated in protecting trees from infestation by bark beetles and phytopathogenic fungi, but it has been difficult to prove these
Induced Terpene Accumulation in Norway Spruce Inhibits Bark Beetle Colonization in a Dose-Dependent Manner
This is the first study demonstrating a dose-dependent relationship between induced terpenes and tree resistance to bark beetle colonization under field conditions, indicating that terpene induction may be instrumental in tree resistance.
Conifer Defense and Resistance to Bark Beetles
Anatomical and chemical defenses of conifer bark against bark beetles and other pests.
This review focuses on bark defenses, a front line against organisms trying to reach the nutrient-rich phloem, and questions about their coevolution with bark beetles are discussed.
Priming for enhanced defense.
This review covers recent advances in disclosing molecular mechanisms of priming, which include elevated levels of pattern-recognition receptors and dormant signaling enzymes, transcription factor HsfB1 activity, and alterations in chromatin state.
Mechanical injury and fungal infection induce acquired resistance in Norway spruce.
Norway spruce trees pretreated by wounding and fungal infection showed highly enhanced resistance to a subsequent challenge inoculation with the pathogenic bluestain fungus Ceratocystis polonica, for the first time the effectiveness of the constitutive and inducible defenses has been shown to depend on prior wounding and infection in conifers.
Defense Priming: An Adaptive Part of Induced Resistance.
Priming is an adaptive strategy that improves the defensive capacity of plants and can be durable and maintained throughout the plant's life cycle and can even be transmitted to subsequent generations, therefore representing a type of plant immunological memory.
Costs and benefits of hormone-regulated plant defences
By combining molecular knowledge and ecological relevance of defence mechanisms, one can gain fundamental insight into how and why plants integrate different immune signals to cope with their natural multitrophic environment in a cost-effective manner.
