Do plants also have fever?

One hundred thousand whys? What does it mean to keep getting points like this?

Belgian scientists have discovered that when plants are infected by viruses, the temperature of leaves and other parts of the plant will rise, causing "fever" symptoms. This phenomenon is similar to when a person's body temperature rises abnormally before an illness such as influenza occurs.

Scientists from Ghent University in Belgium introduced in the latest issue of the journal "Nature Biotechnology" that they used infrared photography to study tobacco infected with tobacco mosaic virus. At least eight hours before any discernible outward symptoms of infection appear, localized "hot spots" actually appear on the tobacco leaves. The temperature rise in these localized "hot spots" on tobacco leaves can reach up to 0.3 to 0.4 degrees Celsius.

Scientists from Ghent University believe that the reason why plants have a "fever" is probably related to the closing of stomata on the surface of leaves. After plants are infected by viruses, the accumulation of salicylic acid in their bodies will increase. Scientists analyzed that salicylic acid will cause the stomata on the surface of plant leaves to close. Since the stomata play a similar role in plants to human sweat glands, after they close, the plant's water loss will decrease, resulting in a "fever" in the plant.
