Exploring wild Solanum germplasm for resistance to ToBRFV (Tomato Brown Rugose Fruit Virus)
ToBRFV is a newly emerged virus that causes severe losses in tomato production. Within five years, ToBRFV infections were reported in Asia, North America and Europe. ToBRFV belongs to tobamovirus genus, however all the available tomato resistant varieties used for tobamoviruses, such as TMV and ToMV, cannot halt infections caused by this new virus. The severity of this disease, its rapid spread, and the scarcity of resistant cultivars make this virus a global threat for tomato production. Our objective is to find ToBRFV resistance in wild Solanum accessions and introgress this trait into tomato cultivars reaching the first step for creating modern resistant tomato varieties. So far, we have screened 75 Solanum accessions from which two S. pennellii found resistant to ToBRFV. Segregation populations have been obtained from these two accession that is the first step for mapping the gene responsible for the resistance trait. The identification and introgression of the resistance gene are in progress.

A Bio-inspired Multilayer Drainage System
Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY
This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735. FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
Environmental monitoring within greenhouse crops using wireless sensors
Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
