Auxin and the Fibonacci Sequence in Gerbera Inflorescences
Gerbera inflorescences are known for their beautiful spirals, which follow the Fibonacci sequence. This sequence is a mathematical pattern where each number is the sum of the two preceding numbers. The sequence starts with 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on. Scientists have been studying the mechanism behind this pattern for years and have recently discovered that auxin plays a crucial role in creating these spirals.
What is Auxin?
Auxin is a plant hormone that regulates growth and development. It is produced in the tips of shoots and roots and moves downwards through the plant. Auxin controls cell elongation, cell division, and differentiation. It also plays a role in phototropism (the bending of plants towards light) and gravitropism (the response of plants to gravity).
The Study
A recent study published in the journal PLOS Biology has shed light on how auxin creates the Fibonacci sequence in gerbera inflorescences. The researchers used computer simulations to model the growth of gerbera inflorescences and found that auxin concentration gradients were responsible for creating the spiral patterns.
How Auxin Creates Spirals
The researchers found that auxin accumulates at the tips of developing petals and then moves downwards towards the base of the flower. As it moves downwards, it creates a concentration gradient that determines where new petals will form. Petals form at points where there is a high concentration of auxin.
The researchers also found that auxin levels oscillate in a periodic manner as new petals form. This oscillation creates waves of high and low auxin concentrations that determine the spacing between petals. The spacing between petals follows the Fibonacci sequence because each new petal forms at a point where the concentration of auxin is a certain distance from the previous petal.
Implications for Plant Growth and Development
Understanding how auxin creates spiral patterns in gerbera inflorescences could have implications for plant growth and development. By manipulating auxin concentrations, scientists may be able to create new patterns in plants or control the spacing between leaves and flowers. This could have applications in agriculture, horticulture, and even architecture.
Conclusion
In conclusion, auxin plays a crucial role in creating the Fibonacci sequence in gerbera inflorescences. By creating concentration gradients and oscillations, auxin determines where new petals will form and how they will be spaced. This discovery could have important implications for plant growth and development, as well as applications in agriculture, horticulture, and architecture.
