Накратко на български

„Възкресителите“ са растения, които оцеляват след пълно изсъхване и възстановяват функциите си при поливане. Анализът на техните гени помага за разбирането на механизмите за издръжливост на суша, което може да подобри качеството и добива на земеделските култури.

Resurrection plants reveal secrets of vegetative desiccation tolerance

A major challenge faced by modern agriculture is plant stress caused by the unfavourable environmental conditions. Global warming is predicted to further intensify these problems, including increasing the frequency and severity of drought stress, which seriously affect both crop quality and yield. Therefore, timely action is needed to find solutions to mitigate the consequences of water deprivation in plants. A small number of species called resurrection plants can tolerate desiccation of their vegetative organs and are a natural resource that can be tapped to solve this problem. They can withstand transition to air-dried state and completely restore physiological activities upon rehydration. Moreover, some of these resurrection species are shown to tolerate other stresses, including low temperature/freezing, severe oxidative stress, and long-term darkness. Therefore, research on resurrection plants has not only significant fundamental scientific importance, it has also immediate practical application, especially in the context of growing population and the ever-increasing demand for higher quality and sustainably produced foods. The interest in these unique plants is additionally fueled by the identification of compounds from resurrection species with medicinal (anticancer and antiviral) activities. However, still little is known about the organization of their genomes and the genetic mechanisms that determine their exotic physiology. The characterization of the genomes of resurrection species, and the identification and functional characterization of important desiccation gene networks, could bring valuable information about the molecular mechanisms of abiotic stress tolerance and identify new strategies that can be used for crop improvement. Therefore, the major goal of this project is to unravel the genetic determinants of desiccation tolerance in resurrection plants and to identify similarities and differences with model and crop species. The newly acquired fundamental knowledge on resurrection plants will be translated to economically important species. A secondary objective will be to explore the possibility of integrating seaweed based stress mitigation technology to improve crop tolerance to drought.

Цел на проекта

A major challenge faced by modern agriculture is abiotic stress caused by unfavourable environmental conditions. Global warming is expected to further intensify these problems, including frequency and severity of drought stress, which seriously affect both crop quality and yield. Therefore, timely action is needed to find solutions to mitigate the consequences of water deprivation. A small number of species called resurrection plants, which can tolerate desiccation of their vegetative organs, are a natural resource that can be tapped to solve this problem. They can withstand transition to air-dried state and completely restore physiological activities upon rehydration. In this project, we will study the genomes of several resurrection species and compare them with the genomes of desiccation-sensitive plants to identify molecular mechanisms that are involved in drought tolerance. In addition to the publicly available data of resurrection plants with already sequenced genomes, we will sequence and analyze two more- Haberlea rhodopensis and Xerophyta humilis. Comparative transcriptomics, metabolomics, and lipidomics of resurrection, model, and crop plants subjected to drought will bring further insights about the nature of drought stress tolerance. The research team involves European specialists in resurrection species, drought signaling, plant systems biology and bioinformatics, a partner from Israel experienced in lipidomics, and the leading African university with expertise in resurrection plants and bioinformatics. Next to that, an industrial partner will ensure that the knowledge gained by studying the resurrection and model species is transferred to crops. Moreover, the company will contribute with novel biostimulant based treatment technologies to mitigate stress and achieve optimal yield and net profit. An extensive mobility program will provide staff exchange to maximize research outputs and increase the human capacity of the partners.
