Like us, plants need water to survive. But this does not mean that the green leaves of trees, shrubs or flowers are enjoying the rain more than people. When the sky appears gray clouds and it starts raining, the reaction of plants on the water droplets that fall from the sky, instant, overwhelming and close to reaction “panic”. To such conclusion scientists from the University of Western Australia. Results published in the journal PNAS. Oddly enough (it is believed that water should bring the plants life, not death), experts believe that moisture is the main pathway for spreading diseases among plants. The longer the leaves remain wet, the greater the likelihood that they will settle the pathogen.
What happens to the plants when it rains?
When a raindrop falls on a leaf, tiny droplets of water ricochet in all directions. These droplets can contain bacteria, viruses or fungal spores. One drop can spread to a distance up to 10 meters and infect a large number of plants. Agree, this is quite frustrating. It turns out that the response of plants to precipitation similar to how people react to the coughing or sneezing of others: it is frustrating and makes taking a defensive stance.

Using spray canisters, which spray like rain, an international team of researchers saw a rapid Domino effect of microscopic changes in the plantsthat run powerful protein Myc2. Although the changes were instant, re-engagement eventually led to the stunting of plants and delayed flowering. When activated Myc2, thousands of genes come into action, preparing the protection of plants, write in their work, scientists. These warning signals are propagated from leaf to leaf and cause a number of protective reactions.
Just it was discovered that at least 20 protein-related genes are directly channeled and regulated by Myc2 after spraying water. Moreover, the same signals that these plants are used for the dissemination of information among the leaves, was also used to communicate with nearby vegetation. One of many chemical substances, produced in response to the falling of the leaves, is jasmonic acid, which regulates many physiological processes associated with plant growth and stress. Plus, when the chemicals jasmonate are in the air, they can also share with other plantswhat is happening and how to handle it. In other words, the plants protect themselves and the adjacent vegetation. What other amazing facts do you know about plants? Share them with members of our Telegram chat.
Earlier this month, another team of researchers found that when plants are exposed to, they develop a universal “language”to warn others. The paper was published in the journal Current Biology. The researchers note that despite the fact that rain is for the plants deadly, occasionally dripping water can lead to disease development. That is why plants, you might say, panic.
