Climate change impacts plants and alters their growth

The incredible ability of plants to live on the Earth is to grow for hundreds of years. They are always directed towards the sun, which gives them the energy they need to sprout.

Changes in their environment, such variations in temperature, light, and humidity, are the main causes of this growth. New stimuli, such as climate change, are disrupting normal growth.

As a doctoral candidate in biochemistry at the University of Québec in Montréal, I am interested in the structure of plant proteins, and study the ways plants adapt to environmental stresses(droughts and colds, deficiencies) molecular levelTo select more resilient varieties for agriculture.

Pando has a longevity unmatched

The The oldest forest on the planetPando is an 80,000 year old tree. It is located in Utah. It contains 40,000 genetically similar (clones), quaking, ortrembling, aspen tree clones. The colony communicates through a single root network.

Pando is believed to be the oldest living organism on the planet. This colony was founded in It took 30,000 years for the first to be discovered. Homo sapiensLocated in Europe. Pando, therefore has been witness to the whole of modern human life. The empires of China, Rome and Japan, World warsAnd also to the greatest achievements of humanity.

Nevertheless, the colony’s Poplars have not grown continuously for 80,000 years. Their thriving population is a testament to their ability to The seasons orchestrate development. They must, however, control their development according to their physical and developmental capabilities to face external aggressions. The external environment can be disrupted and the Climate crisis currently directlyThis regulation affects normal growth.

The secret to plant growth lies in the cell

New organs are created by plants, such as the leaves. Flowers or roots, if necessary to respondTo an external stimulusEnvironment. A change in the light exposure time during spring is one example. Triggers for flowering.

These stimuli activate the DNA by targeting it. Certain genesEach organ is necessary for the growth of an adult plant. DNA is a code that codes for the plant’s physical peculiarities. It can be compared to a dictionary of genetic information. These genes are living words that must also be understood to understand their meaning. Information they contain.

The gene reading phenomenon is responsible for all stages of plant development and growth, including seed germination, flower reproduction, and the formation stems, roots, and leaves. Each word requires specific activators to read it. These activators are required to position themselves at the front line of the gene to express and read the gene if the environment is favorable to growth. The gene encodes a specific growth pattern for the organ..

DELLA proteins determine growth

Because of this, plants can’t afford to keep growing indefinitely. Energy costs for growth. Similar to animals that hibernate in the winter, plants stop growing in the winter. becoming dormantTo survive the season. To do so, plants block the reading of genesThanks to safeguards called DELLA proteins.

These proteins are only found in plants and have been constant throughout evolution. They are particularly abundant in mosses and ferns, conifers, flowering plants, and conifers. DELLAs can be found in the cell nucleusThey are the closest to DNA. They are constantly produced and can block gene activators.

To mature, plants need to destroy the DELLAs that release activators. Plants are capable of releasing activators. This system allows for the labelling of these proteinsTo influence their fate in the cell according their needs. The cell adds small amounts of money to DELLAs to make them less desirable. proteinubiquitin to its surface. Ubiquitin acts as a postage stamp, telling the cell to deliver the DELLAs at a new destination, a “cellular garbage can,” where they will be destroyed.

Climate stress blocks DELLA degradation

Droughts and floods are on the riseAll over the globe. Their inmobility is what makes them so unique. These external attacks are too much for plants to resist. These new environmental parameters can cause stress to wild plants and agricultural crops. Disrupting their growthThey must use energy to survive and not grow, and must not degrade DELLA proteins.

Scientists have now named SUMO a cousin to ubiquitin. This allows the DELLA proteins of the cell to be labelled in a different way. SUMO replaces ubiquitin and acts as a life-buoy to ensure it doesn’t get degraded.

In fact, SUMO labelling occurs exactly where ubiquitin should have been added. SUMO does not allow plants to add ubiquitin. Survive adverse climates events.

It is crucial to understand and investigate the plant growth mechanism in order to maintain sustainability in agricultural crops in the current climate crisis. Researchers are working hard to identify and select the best plant growth mechanisms. PlantsSUMO can be activated quickly in order to allow growth under adverse conditions.
