The plants that live on Earth have the amazing power to grow continuously for hundreds of years, and constantly in the light of the sun, to give them the necessary energy to grow.

The reason for this growth is changes in their environment, such as different types of light, temperature and humidity. But new incentives from the current changes are halting the normal growth of the plants.

As a doctoral doctor in biochemistry at the University of Québec in Montréal, I love the nature of plant proteins, and study the ways in which plants adapt to environmental stressors (drought). , cold, deficiencies) at the molecular level in order to select the resilient. different ways of farming.

Pando is a different length

The oldest forest in the world, called Pando, is 80,000 years old. In Utah there are 40,000 genetically identical (clones) of the vibrate, and vibrate, aspen trees. The colony communicates through a single source network.

Pando is considered to be the oldest living thing in the world. This colony was founded 30,000 years ago Homo sapiens live in Europe. Thus, Pando describes the whole of modern human life: the empires of China and Rome, the world wars and the most important human activities.

However, the poplars of the colony did not grow continuously for 80,000 years. On the other hand, their growth is regulated by the seasons. On the other hand, they need to control their growth according to their physical fitness and ability to withstand outdoor activities. By disrupting the development of the external environment, climate change is directly related to this natural growth regulation.

The secret of the plant’s growth was planted in the room

Plants develop new bodies such as leaves, flowers or roots, as they need to respond to external stimuli from the environment. For example, changing the light season to spring will stimulate the flower.

These promoters create DNA by inducing specific genes for the development of each organ to form a mature plant. DNA is compared to a dictionary of genes that contains the code for the physical characteristics of a plant. These genes are living words that need to be read to express their meaning, and the knowledge within them.

From fruit development to flowering to the formation of stems, roots and leaves, all stages of growth and development depend on an event. read gene. In order to read genes, specific stimuli are needed for each word. If the environmental conditions change and are conducive to growth, then these stimuli place themselves in front of the gene to read and express it, leading to the specific growth of the body that is recorded by the gene. gene.

DELLA proteins regulate growth

Plants cannot grow forever because of the energy cost of growth. In addition, as the animals hibernate, the plants cease to grow during the winter, and become dormant to survive the summer. To do this, plants restrict the reading of genes thanks to proteins called DELLA proteins.

Found only in plants, these proteins are retained during growth. They are found on mosses, ferns, conifers and flowering plants. DELLAs are located in the cell nucleus, very close to DNA. They are often used and can block gene expression.

In order to mature, the plants need to remove the DELLAs to release the nutrients. Plants have developed a system for the registration of these proteins to enhance their effect in the cell according to their needs. To lower DELLA levels, the cell connects a small protein, called ubiquitin, to its skin. Ubiquitin acts as a message board telling the phone to give DELLAs a new journey, a “phone trash can,” where they will be humiliated.

The pressure of the air is holding back the DELLA damage

Droughts and droughts are increasing around the world. Because of their inability, the plants cannot survive these external attacks. These new environments encourage wild and agricultural crops by stopping their growth, which means they need to conserve energy before they can grow. and DELLA proteins should not be degraded.

This requires that the DELLA protein be labeled in a different way, through its ubiquitin relative, called SUMO by scientists. SUMO replaces ubiquitin, which serves as a non -degradable life -sustaining pill.

In fact, the SUMO label is made in the same place where the ubiquitin is added. The passage of SUMO does not allow the addition of ubiquitin, which allows plants to survive adverse events.

In the current climate crisis, it is important to research and understand this type of crop production with the hope of continuing the sustainability of agricultural crops. Researchers are working hard to isolate and select plants that can quickly cure SUMO in order to grow under natural conditions.
