American scientists have discovered that plant seeds can perceive the sound of rain and accelerate germination in response to acoustic waves. This mechanism helps seeds choose the optimal moment for growth.
A new study has shown that the direction of plant growth is determined not only by their tendency to grow upwards, but also by the balance between two signaling systems, including the SLQ1 protein, which stimulates downward growth. This discovery challenges the traditional understanding of gravitropism and helps explain how plants develop their structure.
