Накратко на български

Бактериите в дивите алпийски растения се анализират, за да се разбере как помагат на ябълките да издържат на замръзване. Това е важно, защото естествените микроорганизми могат да намалят щетите от пролетните слани и да подобрят реколтата по устойчив начин.

Understanding the role of microbiome interactions in the freezing stress tolerance of plants

Climate change-associated extreme weather events such as spring frosts have increased in frequency and intensity over the past decades in Europe. Freezing stress is one of the main limiting factors for the production of many fruit crops including apple (Malus × domestica, Rosaceae family). Current methods used by growers to prevent or reduce freezing damage include mainly physical approaches, which have several limitations in terms of cost, efficacy, and environmental impact. Thus, the development of natural approaches for the mitigation of frost damage on crops will provide a sustainable tool for growers with beneficial impacts on society (i.e., high quality and quantity of fruits) and the economy (i.e., sustainable use of natural resources). The use of natural plant-beneficial microorganisms is a promising approach against freezing stress. Plants growing in cold regions, such as Alpine regions, are hypothesized to survive freezing stress thanks to their symbiotic relationship with endophytic microorganisms. However, the structure and function of endophytic microbial communities associated with such plants are poorly understood. FreezingBioprotector project aims to taxonomically and functionally characterize the endophytic bacterial communities associated with wild alpine Rosaceae plants, to develop new microbial-based products for freezing protection of apple. The overall objectives of this project that were each addressed by a work package (WP) are (i) characterising the bacterial communities associated with Dryas octopetala anthosphere and identifying potential bacteria for freezing protection (WP1) (ii) identifying novel bacterial strains by a rapid-throughput screening for their ice-active traits and environmental stress tolerance (WP2) and (iii) identifying bacterial strains with freezing protection abilities on strawberry and feasibility checking of industrial production (WP3).

Цел на проекта

Current methods used by growers to prevent or reduce freezing damage include mainly physical approaches, which haveseveral limitations in terms of cost, efficacy and environmental impact. The use of natural plant beneficial bacteria is apromising approach against freezing damage. With the aim of developing new microbial-based products for freezingprotection of apple, the goal of this project is to taxonomically and functionally characterise the bacterial communitiesassociated with the anthosphere of a wild cold-adapted rosaceous plant (Dryas octopetala) and to assess their freezingprotection abilities on apple. To achieve these goals, we will use the combination of high-throughput sequencing and rapid throughput screening of bacterial isolates with interdisciplinary approaches of molecular biology, bioinformatics, microbiology and plant physiology. In particular, bacterial taxa associated with D. octopetala flowers under freezing stress tolerance will be identified and targeted isolation methods will be used to recover psychrophilic bacteria. Screening of bacterial isolates will be carried out to examine their ice-active traits (ice recrystallization inhibition and ice shaping) and environmental stress tolerance (drought, starving and UV). Efficacy tests of the isolates for their freezing protection abilities on apple will be performed, followed by feasibility checking of industrial production of the best candidates. The scientific outcomes of this project will contribute in the development of a microbial product for freezing protection of fruit crops that will be further developed for the EU market, which agrees with the promotion of sustainable biological methods. FreezingBioprotector will be fundamental to my professional career development by broadening my expertise in microbial ecology and crop protection, as well as transferable skills on teamwork, leadership, analytical thinking and project management that will be essential for my future research career.
