Plants react to rain almost “panic”

According to a study published in the journal PNAS, plants react to rain in a near-panic way. Scientists have revealed complex chemical signals that help plants withstand the risk of rain. Scientists note that when water is sprayed on plants, a protein called Myc2 activates a chain reaction, and thousands of genes behave to prepare a defense system for plants, warning signs that travel between leaves, inducing a series of protective effects.

Why do plants panic about rain? This sounds strange, and the reason is that rain causes disease to spread between plants.

The splashing droplets contain bacteria, viruses, or fungal spores. If a plant starts to defend itself, the likelihood of spreading the disease decreases.
