Plants teach their descendants how to adapt to climate change, scientists say

Can a plant remember?

This may sound more like a line from a poem than scientific research.

But a new analysis suggests that floors they can pass on climate adaptation advice to their offspring.

From devastating floods to rising temperatures, the air-conditioned The crisis is changing natural habitats around the world.

In order to survive, many plants have been forced to change rapidly. fitindicates new research published in the journal Trends in Plant Science.

They then pass these new traits on to their offspring, says Federico Martinelli, a plant geneticist at the University of Florence.

“One day I thought [about] how a person’s lifestyle and experience can affect their gametes [reproductive cells] transmitting molecular marks of his life to his children”, he explains.

“I immediately thought that even more epigenetic marks should be transmitted in floorssince the plants are sessile [fixed in one place] organisms that are subject to much more environmental stress than animals during their lifetimes.

How do plants adapt to climate change and do they remember these adaptations?

Changes in the environment force animals to change, altering their hunting and hibernation patterns and changing habitats.

The plants are rooted in the place, but they also change.

For example, winters, which plants use to guide their flowering time, have become warmer and shorter in many regions.

“A lots of floors they require a minimum period of cold to start their environmental clock to define their flowering time”, says Martinelli.

“As cold seasons have shortened, plants have adapted to require fewer cold spells to delay bloom. These mechanisms allow plants to avoid flowering in periods when they are less likely to reproduce.”

Floors they don’t make memories in the same way that humans do, but they do remember. Instead of storing memories in the brain (neural networks), they store them in sophisticated cellular and molecular signaling networks.

The researchers call this a “somatic memory”, stored in the body of the plant.

“These mechanisms allow plants to recognize the occurrence of a previous environmental condition and to react more quickly in the presence of the same consequent condition,” says Martinelli.

For example, a plant you can remember to delay flowering when it is warmer.

It will pass this trait on to its offspring through something researchers call “epigenetics.”

Unlike genetic changes, epigenetic changes do not change a DNA sequence. Instead, they can change the way an organism reads a DNA sequence.

“Epigenetic modifications are inherited…thus contributing to the long-term adaptation of plant species to climate change”, write the authors of the article.

The research will help scientists understand how plant intelligence is fighting climate change.
