Myrcene is the most abundant terpene in cannabis, which is where it’s mostly found in nature. In fact, one study showed that myrcene makes up as much as 65% of total terpene profile in some strains. Myrcene smell often reminds of earthy, musky notes, resembling cloves. Also, it has a fruity, red grape-like aroma. Strains that contain 0.5% of this terpene are usually indicas with sedative effects. It has also been reported that myrcene is useful in reducing inflammation and chronic pain, which is why it’s usually recommended as a supplement during cancer treatments. Strains that are rich in myrcene are Skunk XL, White Widow, and Special Kush. Bonus tip: If you want to experience a stronger buzz from marijuana, get yourself a mango and eat it about 45 minutes before smoking. Mango contains significant amount of myrcene, so eating it before consuming cannabis will strengthen the effects of THC and increase its absorption rate.

Limonene is the second most abundant terpene in all cannabis strains, but not all strains necessarily have it. As its name says, limonene gives strains a citrusy smell that resembles lemons, which is no surprise as all citrus fruits contain large amounts of this compound. For therapeutic purposes, limonene is known to improve mood and reduce stress. Researchers also found it to have antifungal and antibacterial properties and one research even found it to have a role in reducing tumor size.

Strains that have “lemon” or “sour” in their name are usually rich in limonene. High levels of limonene can be found in strains like O.G. Kush, Sour Diesel, Super Lemon Haze, Durban Poison, Jack Herer, and Jack the Ripper.

This terpene is the most responsible for the recognizable marijuana smell with its spicy and floral notes. Linalool is also found in lavender, mint, cinnamon and coriander. What’s interesting is that just like those aromatic herbs, it has very strong sedative and relaxing properties.

Patients suffering from arthritis, depression, seizures, insomnia and even cancer, have all found aid in this amazing terpene. Some well known linalool strains are Amnesia Haze, Special Kush, Lavender, LA Confidential, and OG Shark.

Best known for its spicy and peppery note, caryophyllene is also found in black pepper, cinnamon, cloves, and spices like oregano, basil and rosemary. Beta-caryophyllene binds to CB2 receptors, which makes it an ingredient in anti-inflammatory topicals and creams. Caryophyllene is the only terpene that binds to cannabinoid receptors.

Besides its analgesic and anti-anxiety properties, some studies have found that caryophyllene has some very promising properties when it comes to alcoholism rehabilitation.
You can benefit from caryophyllene by using strains like Super Silver Haze, Skywalker and Rock Star.

Alpha-pinene and Beta-pinene
These two cannabis terpenes smell like pine trees and that’s also where they can be found in large amounts. Other plants rich in pinene include rosemary, orange peels, basil, parsley and cannabis.

Like many other, pinene terpenes have an anti-inflammatory effect on humans. But more importantly, they help improve airflow and respiratory functions, while also helping to reduce memory loss related to THC. I know that this can sound weird because we’re talking about cannabis, but if the strain is rich in alpha and beta pinene, it can actually help with asthma.

Pinene also helps patients with arthritis, Crohn’s disease and cancer. You can find pinene in strains like Jack Herer, Strawberry Cough, Blue Dream, Island Sweet Skunk, Dutch Treat and Romulan.

Alpha-bisabolol (also known as levomenol and bisabolol) has a pleasant floral aroma and can also be found in chamomile flower and candeia tree. This terpene found its use primarily in the cosmetics industry, but lately it has caught the attention of researchers since it showed medical benefits, especially in cannabis.

Alpha-bisabolol proved to be effective in treating bacterial infections and wounds and is a great antioxidant with anti-irritation and analgesic properties. It can be found in strains like Harle-Tsu, Pink Kush, Headband, OG Shark, and ACDC.


This one is a secondary terpene found mostly in flowers like jasmine, lemongrass, and tea tree oil. The smell of trans-nerolidol reminds of a mixture of rose, citrus and apples and can be described in general as woody, citrus and floral.

Trans-nerolidol is best known for its antiparasitic, antioxidant, antifungal, anticancer and antimicrobial properties. Strains like Island Jack Herer, Sweet Skunk, and Skywalker OG are rich in nerolidol.

Humulene was the first terpene found in hops. Its aroma contains earthy, woody and spicy notes.

Besides cannabis, it can be also found in clove, sage, and black pepper. It has a variety of medical properties. Early research has shown humulene to be anti-proliferative, meaning it prevents cancer cells from growing. Also, it proved to be effective in suppressing appetite, making it a potential weight loss tool. Furthermore, like many other cannabis terpenes mentioned above, it also reduces inflammation, relieves pain and fights bacterial infections. You can find humulene in strains like White Widow, Headband, Girl Scout Cookies, Sour Diesel, Pink Kush and Skywalker OG.

Delta 3 Carene
This terpene is found in a number of plants like rosemary, basil, bell peppers, cedar and pine. Its aroma is sweet and resembles the smell of cypress tree. When it comes to the medical side of carene, it seems to be mostly beneficial in healing broken bones. That gives hope to patients suffering from osteoporosis, arthritis and even fibromyalgia.

What is also interesting about this terpene is that it stimulates our memory and helps memory retention. This is a major point in finding a cure for Alzheimer’s disease.

The best way to describe the smell of camphene is fir needles, musky earth and damp woodlands. Camphene aroma is often mistaken with myrcene, which is that trademark marijuana smell as most of us know it. From the medical point of view, camphene has great potential. When mixed with vitamin C, it becomes a powerful antioxidant.

It is widely used in conventional medicine as a topical for skin issues like eczema and psoriasis. Its greatest potential lies in its ability to lower the levels of cholesterol and triglycerides in the blood, further lowering the risk of cardiovascular diseases. Camphene is present in Ghost OG, Strawberry Banana, Mendocino Purps.

Borneol, with its herbal minty scent, can be found in herbs like rosemary, mint and camphor.

This terpene is a good natural insect repellent which makes it great in preventing diseases like the West Nile virus, being passed by ticks, fleas, mosquitoes etc. One study found that borneol kills breast cancer cells. It’s also widely used in Chinese traditional medicine, in acupuncture to be precise. Strains high in borneol are Amnesia Haze, Golden Haze, K13 Haze.

The aroma of terpineol can be best described as floral-like, reminiscent of lilacs, apple blossom, and a little bit citrusy. Terpineol tastes like anise and mint. Terpineol has a pleasant scent, similar to lilac, and is a common ingredient in perfumes, cosmetics, and flavors.

It relaxes heavily and it’s usually the one responsible for the notorious couch lock effect. Medical benefits of terpineol also include antibiotic and antioxidant properties. It can be found Girl Scout Cookies, Jack Herer, and OG Kush strains.

This terpene got its name from sweet Valencia oranges — where it’s been found in large amounts. With its sweet citrusy aromas and flavors, it’s used as an insect repellant, too. Valencene can be found in strains like Tangie and Agent Orange.

Besides cannabis, geraniol can be found in lemons and tobacco. Its smell reminds of rose grass, peaches and plums. Geraniol has shown a lot of potential as a neuroprotectant and antioxidant.
It is present in strains like Amnesia Haze, Great White Shark, Afghani, Headband, Island Sweet Skunk, OG Shark and Master Kush.

Dimethylallyl pyrophosphate​

Dimethylallyl pyrophosphate (DMAPP; or alternatively, dimethylallyl diphosphate (DMADP); also isoprenyl pyrophosphate) is an isoprenoid precursor. It is a product of both the mevalonate pathway and the MEP pathway of isoprenoid precursor biosynthesis. It is an isomer of isopentenyl pyrophosphate (IPP) and exists in virtually all life forms. The enzyme isopentenyl pyrophosphate isomerase catalyzes isomerization between DMAPP and IPP.[1]

In the mevalonate pathway DMAPP is synthesised from mevalonic acid. In contrast, DMAPP is synthesised from HMBPP in the MEP pathway.

At present, it is believed that there is crossover between the two pathways in organisms that use both pathways to create terpenes and terpenoids, such as in plants, and that DMAPP is the crossover product.
3-methylbut-2-en-1-yl diphosphate
Other names
Dimethylallyl diphosphate; isoprenyl pyrophosphate; isoprenyl diphosphate

Isoprene is produced and emitted by many species of trees (major producers are oaks, poplars, eucalyptus, and some legumes).

Isoprene emission in plants is controlled both by the availability of the substrate (DMAPP) and by enzyme (isoprene synthase) activity. In particular, light, CO2 and O2 dependencies of isoprene emission are controlled by substrate availability, whereas temperature dependency of isoprene emission is regulated both by substrate level and enzyme activity.

Isoprene emission appears to be a mechanism that trees use to combat abiotic stresses.[


The isoprene skeleton can be found in naturally occurring compounds called terpenes (also known as isoprenoids), but these compounds do not arise from isoprene itself. Instead, the precursor to isoprene units in biological systems is dimethylallyl pyrophosphate (DMAPP) and its isomer isopentenyl pyrophosphate (IPP). The plural 'isoprenes' is sometimes used to refer to terpenes in general.

Examples of isoprenoids include carotene, phytol, retinol (vitamin A), tocopherol (vitamin E), dolichols, and squalene. Heme A has an isoprenoid tail, and lanosterol, the sterol precursor in animals, is derived from squalene and hence from isoprene. The functional isoprene units in biological systems are dimethylallyl pyrophosphate (DMAPP) and its isomer isopentenyl pyrophosphate (IPP), which are used in the biosynthesis of naturally occurring isoprenoids such as carotenoids, quinones, lanosterol derivatives (e.g. steroids) and the prenyl chains of certain compounds (e.g. phytol chain of chlorophyll). Isoprenes are used in the cell membrane monolayer


So if you have a strain that is known to produce a certain terp, can you really target them and enhance that particular terp?

I've been gathering as many research papers on Cannabis, terps and their effects together as I can find (for free). There's a lot of research that still needs to be done, especially for the recreational aspect, IMO.

Evolution of plant transcriptional regulation​

Transcription factors and transcriptional regulatory networks play key roles in plant development and stress responses, as well as their evolution. During plant landing, many novel transcription factor families emerged and are preferentially wired into the networks of multicellular development, reproduction, and organ development, contributing to more complex morphogenesis of land plants.

CoRR hypothesis​

The CoRR hypothesis states that the location of genetic information in cytoplasmic organelles permits regulation of its expression by the reduction-oxidation ("redox") state of its gene products.
CoRR is short for "co-location for redox regulation", itself a shortened form of "co-location (of gene and gene product) for (evolutionary) continuity of redox regulation of gene expression".
Control of gene expression by redox potential and the requirement for chloroplast and mitochondrial genomes"

Yes, I believe so. I think strains can be modified, evolved or even artificially assisted to uptake specific preconfigured ratios of a Supramolecular chemical species. No doubts whatsoever in my mind that some of my cultivars are evolving. If the plant is exposed to certain biologically active conditions, agents, enzymes, fungi, bacteria, viruses, protozoa eventually those functions will become incorporated into the (DNA) genetic makeup of the specific cultivar in question.

I think the best way to approach something like this is to start with the actual terpene we are targeting, then deconstruct it (into substrate) then enable the plant to re-uptake it again. Seems to me to be the easiest place to start using an approach such as this. That's why if you note, in the above post I have listed all the relevant "terpenes" and other plants that they exist in.... ie. lavender, lemon grass, sage, cloves, mint, whatever...

If these products are first purified, then decomposed, they should be readily available for uptake again in an extremely accurate ratio config.

However it seems Bacteria, Fungi, enzymes and other microorganisms appear to hold many of the keys thrusting evolution forward....


Cyanobacteria and the evolution of photosynthesis​

Cyanobacteria remained principal primary producers throughout the Proterozoic Eon (2500–543 Ma), in part because the redox structure of the oceans favored photoautotrophs capable of nitrogen fixation. Green algae joined blue-greens as major primary producers on continental shelves near the end of the Proterozoic, but only with the Mesozoic (251–65 Ma) radiations of dinoflagellates, coccolithophorids, and diatoms did primary production in marine shelf waters take modern form. Cyanobacteria remain critical to marine ecosystems as primary producers in oceanic gyres, as agents of biological nitrogen fixation, and, in modified form, as the plastids of marine algae.

Symbiosis and the origin of chloroplasts​

Chloroplasts have many similarities with cyanobacteria, including a circular chromosome, prokaryotic-type ribosomes, and similar proteins in the photosynthetic reaction center.[17][18] The endosymbiotic theory suggests that photosynthetic bacteria were acquired (by endocytosis) by early eukaryotic cells to form the first plant cells. Therefore, chloroplasts may be photosynthetic bacteria that adapted to life inside plant cells. Like mitochondria, chloroplasts still possess their own DNA, separate from the nuclear DNA of their plant host cells and the genes in this chloroplast DNA resemble those in cyanobacteria. DNA in chloroplasts codes for redox proteins such as photosynthetic reaction centers. The CoRR hypothesis proposes that this Co-location is required for Redox Regulation.

Transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. The function of TFs is to regulate—turn on and off—genes in order to make sure that they are expressed in the right cell at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth, and cell death throughout life; cell migration and organization during embryonic development; and intermittently in response to signals from outside the cell, such as a hormone. Transcription factors are members of the proteome as well as regulome.

TFs work alone or with other proteins in a complex, by promoting (as an activator), or blocking (as a repressor) the recruitment of RNA polymerase (the enzyme that performs the transcription of genetic information from DNA to RNA) to specific genes.

A defining feature of TFs is that they contain at least one DNA-binding domain (DBD), which attaches to a specific sequence of DNA adjacent to the genes that they regulate. TFs are grouped into classes based on their DBDs. Other proteins such as coactivators, chromatin remodelers, histone acetyltransferases, histone deacetylases, kinases, and methylases are also essential to gene regulation, but lack DNA-binding domains, and therefore are not.


Transcription factors and methylated cytosines in DNA both have major roles in regulating gene expression. In the chemical sciences, methylation denotes the addition of a methyl group on a substrate, or the substitution of an atom (or group) by a methyl group. Methylation is a form of alkylation, with a methyl group replacing a hydrogen atom. It play's a significant role in modulating development of THC, among many other roles...

A cellular proteome is the collection of proteins found in a particular cell type under a particular set of environmental conditions such as exposure to hormone stimulation. The proteome is the entire set of proteins that is, or can be, expressed by a genome, cell, tissue, or organism at a certain time. It is the set of expressed proteins in a given type of cell or organism, at a given time, under defined conditions.


Regulome refers to the whole set of regulatory components in a cell. Those components can be regulatory elements, genes, mRNAs, proteins, and metabolites. The description includes the interplay of regulatory effects between these components, and their dependence on variables such as subcellular localization, tissue, developmental stage, and pathological state.

Transcription factor glossary
  • gene expression – the process by which information from a gene is used in the synthesis of a functional gene product such as a protein
  • transcription – the process of making messenger RNA (mRNA) from a DNA template by RNA polymerase
  • transcription factor – a protein that binds to DNA and regulates gene expression by promoting or suppressing transcription
  • transcriptional regulationcontrolling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA
  • upregulation, activation, or promotionincrease the rate of gene transcription
  • downregulation, repression, or suppressiondecrease the rate of gene transcription
  • coactivator – a protein (or a small molecule) that works with transcription factors to increase the rate of gene transcription
  • corepressor – a protein (or a small molecule) that works with transcription factors to decrease the rate of gene transcription
  • response element – a specific sequence of DNA that a transcription factor binds to

One of the major players in cellular regulation are transcription factors, proteins that regulate the expression of genes. Other proteins that bind to transcription factors to form transcriptional complexes might modify the activity of transcription factors, for example blocking their capacity to bind to a promoter.

Signaling pathways are groups of proteins that produce an effect in a chain that transmit a signal from one part of the cell to another part, for example, linking the presence of substance at the exterior of the cell to the activation of the expression of a gene.

The complete knowledge of the regulome will allow researchers to model cell behaviour entirely.
