Plants Found to 'Hear' Rain, Boosting Seed Germination Speed

A new MIT-led study has found that rice seeds can sense the sound of rain, prompting them to sprout up to 40% faster.
Researchers discovered that rain-induced vibrations jostle statoliths—gravity-sensing structures in seeds—triggering accelerated germination when seeds are submerged in water.
This is the first direct evidence that plant seeds respond to natural sounds, suggesting an evolutionary advantage in sensing environmental cues like rain.
How does the sound of rain trick a seed's gravity sensors into starting growth?
Could farmers soon use 'sound irrigation' to accelerate crop germination and save water?
Is human noise pollution making plants deaf to the life-giving sound of rainfall?
If stressed plants emit ultrasonic clicks, can other plants actually hear their warnings?
Could a false rain signal trigger premature germination, dooming a seed before a drought?
What secret acoustic conversations are happening between plants, insects, and the environment?
