eserved in vacuoles of polyphenolic parenchyma cells (PP) in the secondary phloem.

Induced defenses
Induced defense responses need to be activated by certain cues, such as herbivore damage or other biotic signals.

A common induced defense mechanism used by Pinaceae is resins. Resins are also one of the primary defenses used against attack. Resins are short term defenses that are composed of a complex combination of volatile mono- (C10) and sesquiterpenes (C15) and nonvolatile diterpene resin acids (C20). They are produced and stored in specialized secretory areas known as resin ducts, resin blisters, or resin cavities. Resins have the ability to wash away, trap, fend off antagonists, and are also involved in wound sealing. They are an effective defense mechanism because they have toxic and inhibitory effects on invaders, such as insects or pathogens. Resins could have developed as an evolutionary defense against bark beetle attacks. One well researched resin present in Pinaceae is oleoresin. Oleoresin had been found to be a valuable part of the conifer defense mechanism against biotic attacks. They are found in secretory tissues in tree stems, roots, and leaves. Oleoresin is also needed in ord
 er to classify conifers.

Active research: methyl jasmonate (MJ)
The topic of defense mechanisms within family Pinaceae is a very active area of study with numerous studies being conducted. Many of these studies use methyl jasmonate (MJ) as an antagonist. Methyl jasmonate is known to be able to induce defense responses in the stems of multiple Pinaceae species. It has been found that MJ stimulated the activation of PP cells and formation of xylem traumatic resin ducts (TD). These are structures that are involved in the release of phenolics and resins, both forms of def
