Genetic mutations , most often described as errors in the genetic code, are in fact the driving force behind evolution and diversity in the living world. In the complex field of cannabis, these random changes in the DNA or RNA sequence generate a variety of unique characteristics.
In this article, we will delve into the world of genetic changes in cannabis, exploring their nature, causes, consequences, and how they shape plant diversity.
What are the underlying causes of genetic mutations?
These are random alterations in the sequence of nucleotides in DNA or RNA, the molecular building blocks of life.
Every living thing, including cannabis, has a unique set of genetic instructions that determine its characteristics and function. DNA and RNA are made up of long chains of nucleotides , and most mutations result in a change to only one nucleotide out of the billions that make up the genome.
These minute variations are responsible for genetic diversity at the species level, an essential driver of evolution and adaptation.
What are the causes and repercussions of genetic mutations?
This set of phenomena arises during cell division and sometimes results from errors in the DNA replication process.
DNA repair mechanisms are normally activated to preserve genetic integrity; however, occasional errors can occur and induce mutations.
These different genetic variations can result from additions, deletions, or substitutions of nucleotide bases, thereby disrupting the sequence.
This random alteration can lead to new and sometimes surprising characteristics.
The impact of mutations varies. Several of them prove beneficial, others are harmful, while some remain imperceptible.
In general, mutations alter the structure, color, shape of leaves, germination rate, yield, and photosynthetic capacity of plants.
Many changes can be reproduced and selected to develop particular traits. For example, a favorable mutation would likely increase disease resistance or improve yield.
What are the changes occurring in the context of cannabis?
Cannabis is a plant with unique and varied properties that does not escape the forces of evolution through these genetic changes.
All these random phenomena occur during cell division, but can also be induced by exposure to chemical agents or radiation.
These genetic variations influence various aspects of cannabis, such as structure, color, leaf shape, and yield.
Some mutations can be visible, such as variety or albinism, while others, more subtle, represent the chemical composition and traits of the plant.
What are the changes in cannabis culture?
Cuttings, although identical replicas of the mother plant, are not immune to mutations. Over time, cuttings can also exhibit genetic variations.
The phenomenon of clonal degradation suggests that genetic differences become more pronounced between the mother plant and subsequent generations of cuttings, potentially affecting plant health and robustness. This genetic variation can lead to a decrease in plant quality and yield over time.
Co-founder of CBD.fr
Julien Cordobes is the editor of CBD.fr. Born in 1978 in the Paris region, he first trained in e-commerce before turning to natural health approaches, a dual perspective that now structures his way of writing about cannabidiol: reading the scientific literature as it is, without hardening the conclusions, and presenting it in a language that everyone understands.
He discovered CBD at a time when the French market was developing faster than the information available to it. He acquired CBD.fr in 2022 and then took on editorial responsibility for the blog. Since then, he has published numerous articles covering the daily use of CBD, the interpretation of laboratory analyses, the evolution of the legal framework, and precautions for use.
