Накратко на български

Автофагията при ягодите изследва как клетките рециклират компонентите си по време на узряването на плода и при недостиг на вода. Разбирането на тези процеси помага за създаването на сортове, които се справят по-добре с глобалното затопляне и сушата.

Identification of the role of autophagy during fruit ripening and stress resistance in Strawberry: Autophagy manipulation as a way to improve Strawberry fitness

Cells are small factories producing essential components for life. At certain moments they must also recycle those components in order to transform them into new building blocks or energy. This recycling process, called autophagy, it is very important for the development of life beings. Since plants cannot move, their only way to counteract stressful situation such nutrients depletion or water shortages is by modifying their metabolism and making a more efficient use of the available resources. Autophagy, by the recycling of unneeded or superfluous cellular components, has an important role in their response to these stressful situations Strawberry is one of the most important crops in the south of Spain, being the first producer in Europe early in the year. Along its ripening, the strawberry fruit undergoes a number of changes as increasing in size, increasing in sweetness, color change and softening due to degradation of cell wall components. The present situation of global warming it is already having an effect over Spanish climate, with longer and dryer summers. This situation will undoubtedly have an impact in the crop production so the increase in the knowledge about the processes that direct fruit ripening and resistance to stress is crucial in order to develop varieties with better performance against these situations. Based on previous data from the host group, we thought that autophagy could be taking place during strawberry ripening and might have a role in stress resistance. Therefore, the main objective of this project was to study autophagy during the development of strawberry fruit, with special emphasis on maturation/ripening process and in the response to abiotic stress.

Цел на проекта

Autophagy, the major catabolic pathway in eukaryotic cells, has a role in the resistance to biotic and abiotic stresses in different plant species. Plenty of studies show that blocking autophagy by knocking out some of its essential genes leads to plants highly susceptible to this stresses (including heat and drought). However, there are much less studies about the effect of autophagy induction on the response of plants to stresses. Present situation of global warming is already having an effect in agriculture due to a rise in temperature and to water shortages. Therefore, generation of crops with higher resistance to heat and drought should be a priority nowadays. In this proposal I will study the role of autophagy in the maturation of one of the most important berry fruit in EU, Strawberry (Fragaria x ananassa). I will determine the importance of this catabolic process in the response to heat/drought stress in this crop. Furthermore, I will use the diploid strawberry model specie Fragaria vesca to generate transgenic plants with increased autophagy by CRISPR/Cas9 and CRISPR/dCas9 genome editing and analyze the potential benefits regarding general development, fruit quality and stress resistance (this previously shown for Arabidopsis, tomato and apple) that this plants can have compare to wild type. This will be the first basic and applied study of autophagy in strawberry. ""FrATGaria"" will combine my experience in the autophagy field with the expertise of the host group in strawberry development and fruit ripening and will benefit from active collaboration with strawberry breeding groups. The development of this project will allow me to broaden my knowledge about plant development in response to stress strengthening not only my scientific skills but also my leadership, project managment and mentoring capabilities.""
