Terpenoids are characteristic constitutive and inducible defense chemicals of conifers. The biochemical regulation of terpene formation, accumulation, and release from conifer needles was studied in Norway spruce [Picea abies L. (Karst)] saplings using methyl jasmonate (MeJA) to induce defensive responses without inflicting physical damage to terpene storage structures. MeJA treatment caused a 2-fold increase in monoterpene and sesquiterpene accumulation in needles without changes in terpene… 

Figures and Tables from this paper

Methyl jasmonate treatment of mature Norway spruce (Picea abies) trees increases the accumulation of terpenoid resin components and protects against infection by Ceratocystis polonica, a bark beetle-associated fungus.
TLDR
The observed chemical and anatomical changes in response to MJ treatment were correlated with increased resistance to C. polonica, suggesting that terpenoid oleoresin may function in defense against this pathogen.
Insect-Induced Conifer Defense. White Pine Weevil and Methyl Jasmonate Induce Traumatic Resinosis, de Novo Formed Volatile Emissions, and Accumulation of Terpenoid Synthase and Putative Octadecanoid Pathway Transcripts in Sitka Spruce1[w]
TLDR
Overall, weevils and MeJA induced similar, but not identical, terpenoid defense responses in Sitka spruce, with increased levels of weevil- and Me JA-induced TPS transcripts accompanied major changes in terpenoids accumulation in stems.
Conifer terpene synthases : functions in induced plant defense, phylogenetic analyses, & molecular modeling
TLDR
The studies presented here describe the complex changes induced after methyl jasmonate (MeJA) treatment in Norway spruce and have provided a new basis to re-examine the phylogeny of the gymnosperm TPS-d subfamily and the TPS family overall.
Effect of Drought and Methyl Jasmonate Treatment on Primary and Secondary Isoprenoid Metabolites Derived from the MEP Pathway in the White Spruce Picea glauca
White spruce (Picea glauca) emits monoterpenes that function as defensive signals and weapons after herbivore attack. We assessed the effects of drought and methyl jasmonate (MeJA) treatment, used as
The induced chemical defenses of norway spruce [Picea abies (L) Karst.] : ecological function and regulation
TLDR
Induced defenses such as formation of traumatic resin ducts, enhancement of resin flow, and increased accumulation of volatile terpenes and diterpene resin acids, all triggered by application of jasmonates, play a significant role in Norway spruce defense against multiple enemies.
Methyl jasmonate does not induce changes in Eucalyptus grandis leaves that alter the effect of constitutive defences on larvae of a specialist herbivore
TLDR
Findings concur with mounting evidence that most evergreen perennial plants lack foliar-induced defences and suggest that constitutively expressed secondary metabolites other than those commonly examined in studies of interactions between insect herbivores and Eucalyptus may be important in plant defence.
Functional Characterization of Nine Norway Spruce TPS Genes and Evolution of Gymnosperm Terpene Synthases of the TPS-d Subfamily1[w]
TLDR
Phylogenetic analyses based on the inclusion of nine additional terpene synthase (TPS) cDNAs from Norway spruce revealed that functional specialization of conifer TPS occurred before speciation of Pinaceae and the TPS-d subfamily is divided into three groups according to sequence similarities and functional assessment.

TLDR
The traumatic resin response in Norway spruce is analyzed further at the molecular genetic level and the enzyme encoded by PaJF67 forms stereospecifically (+)-3-carene, a characteristic monoterpene of constitutive and induced oleoresin defense of NorwaySpruce and other members of the Pinaceae.
Methyl Jasmonate Induces Traumatic Resin Ducts, Terpenoid Resin Biosynthesis, and Terpenoid Accumulation in Developing Xylem of Norway Spruce Stems1
TLDR
The induction of a complex defense response in Norway spruce by methyl jasmonate application provides new avenues to evaluate the role of resin defenses for protection of conifers against destructive pests such as white pine weevils, bark beetles, and insect-associated tree pathogens.

Patterns of induced and constitutive monoterpene production in conifer needles in relation to insect herbivory
TLDR
It is concluded that the volatile losses caused by tissue damage compensate for herbivore-induced monoterpene synthesis, resulting in no change in pool size, and the induction of new monoterPene synthesis may have a role in replacing monoterpenes lost through damage-induced volatilization and preventing extreme compromise of the constitutive defense system.

TLDR
The induction of predator attractants in plants by JA may be applied in biological control programs, which is discussed in this paper.
Regulation of oleoresinosis in grand fir (Abies grandis). Differential transcriptional control of monoterpene, sesquiterpene, and diterpene synthase genes in response to wounding
TLDR
The differential timing in the production of oleoresin components of this defense response is consistent with the immediate formation of monoterpenes to act as insect toxins and their later generation at solvent levels for the mobilization of resin acids responsible for wound sealing.
Differential induction of plant volatile biosynthesis in the lima bean by early and late intermediates of the octadecanoid-signaling pathway.
TLDR
The differential induction of volatiles resembles previous findings on signal transduction in mechanically stimulated tendrils of Bryonia dioica.

TLDR
Grand fir saplings are a suitable model for studies of the regulation of defensive oleoresinosis in conifers and the restoration of cyclase activity (both constitutive and wound induced) to control levels is indicated.

TLDR
The large quantitative differences between intact plants and detached leaves suggest that the results of assays using excised tissues should be cautiously interpreted when considering intact-plant models.
