Determine a mechanism that allows plants to respond to continuous environmental stress
In the current context ClimateWhere environmental conditions cannot be predicted increasingly and extreme, select Resistance mechanisms The plants have a key to ensuring crops and food security. Now, a team of scientists from the Ptoleanal and Mediterranean Institute has discovered Hortoprumanto La Majura (mixed CSIC Center and Malla Malla) is a molecular mechanism used by plants Stay in persistent stress conditions.
The search, whose details were published on Monday in the magazine The facts of the National Academy of Sciences (PNAS), presented in cooperation with Biological Research Center Margareta Salas, with the regular regular school in Lyon (France) and with Rocamstad’s research, in the United Kingdom. The study focuses on proteins in points called “Communication sites”They are the small areas inside the vegetable cells that unite the outer membrane (plasma) for the interior (retina) without merged.
These proteins work Bridges between both membranesMaking “highways” to transport fats that act as signs that warn the factory that it must adapt to respond to unfavorable environmental conditions. This is a continuous recycling system from fat These signal particles are allowed not to exhaust them And that the plant is always “alert.” The goal of the team, from now on, is to try to modify, improve or improve this recycling mechanism, or set molecular methods such as Jin edition Or looking for plants that have a variation in this response.
In nature, plants do not grow in “optimum conditions” because “in the morning They do not have the same temperature This is at night, nor is this the same in January as in August. The factory is always subject to environmental stress, that is, all of these cases that prevent the plant from growing with its maximum potential. ”Miguel Angel Potila explains to EF The temperature, light and soil formationEtc.
The researcher says that knowing what the natural mechanisms of defense or protection that the factory enjoys are necessary to repeat them in crops and get these stress cases better. When the plant is affected by stress, it stimulates an automatic response, Alert It is produced by fats that are the plasma membrane, which is the outer part of the cell. By using genetics, molecular techniques, advanced skilled and fat analysis, the authors discovered that these fats It is constantly recycled Moving from the outer to the inner membrane thanks to a specific protein that transports them to the plasma membrane.
In this way, the factory gets these fat molecules – otherwise they will end – can renew and continue blood circulation. ” Keep making your mission: To notify the factory that you must adapt to harmful climatic conditions and implement adaptation mechanisms, to summarize the bottle. For example, in front of dehydration, these plant molecules are active To close menstruation and not to lose water Or, if the roots do not find water, send a signal until the root continues until you find high humidity areas, “the researcher explains.
