=== Active research: methyl jasmonate ===
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.<ref name=":6" /><ref name=":9" /><ref name=":10">{{Cite journal|last1=Fäldt|first1=Jenny|last2=Martin|first2=Diane|last3=Miller|first3=Barbara|last4=Rawat|first4=Suman|last5=Bohlmann|first5=Jörg|date=2003-01-01|title=Traumatic resin defense in Norway spruce (Picea abies): Methyl jasmonate-induced terpene synthase gene expression, and cDNA cloning and functional characterization of (+)-3-carene synthase|journal=Plant Molecular Biology|language=en|volume=51|issue=1|pages=119–133|doi=10.1023/A:1020714403780|pmid=12602896|s2cid=21153303|issn=0167-4412}}</ref> Methyl jasmonate is known to be able to induce defense responses in the stems of multiple ''Pinaceae'' species.<ref name=":6" /><ref name=":10" /> 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 defense mechanism.<ref name=":6" /><ref name=":9" />
