Our main research line is separation of organic molecules in extraterrestrial soils and in earthly crops with the purpose of developing terraforming strategies and sustainable space technologies. We select, test, and train plants and other lower eukaryotes for space missions. In addition, we develop hardware and software solutions for solving analytical challenges in space discovery.
Effect of herbicides on soil respiration: a case study conducted at Debrecen-Látókép Plant Cultivation Experimental Station
Sándor Z, Kincses I, Tállai M et al. F1000Research 2020, 9:1348 (https://doi.org/10.12688/f1000research.27057.1)
Measuring the effect of herbicides on the natural environment is essential to secure sustainable agriculture practices. Amount of carbon dioxide released by soil microorganisms (soil respiration) is one of the most important soil health indicators, known so far. In this paper we present a comprehensive quantifying study, in which we measured the effect of 14 herbicides on soil respiration over 16 years, from 1991 to 2017, at Debrecen-Látókép Plant Cultivation Experimental Station. Investigated herbicides contained different active ingredients and were applied in various doses. It was found that 11 out of the examined 14 herbicides had a detrimental effect on soil respiration.
Determination of complex type free, non‐conjugated Oligosaccharide Glucose Unit values in tomato xylem sap for early detection of nutrient deficiency
Mátyás, B., Singer, J., Szarka, M., Lowy AD., Döncző, B., Makleit, P., Failoc-Rojas, VE., Ramirez, A., Martínez, P., Sándor, Zs., Kincses, I., Guttman, A. (2020) ELECTROPHORESIS. Accepted Author Manuscript. doi:10.1002/elps.202000254
Although knowledge on glycan biosynthesis and processing is continuously maturing, there are still a limited number of studies that examine biological functions of N‐glycan structures in plants, which remain virtually unknown. Here we report statistical correlation between nutrient (nitrogen) deficiency symptoms of crops and changes in APTS‐labeled complex type free oligosaccharides. While deficiency symptoms are predicted by multispectral images and Kjeldahl digestion, APTS‐labeled complex type free oligosaccharides are identified by their Glucose Unit (GU) values in tomato xylem sap, using capillary electrophoresis with laser induced fluorescence detection (CE‐LIF). Given the limited number of structures obtained from plants, archived in the literature, in the future we intend to create an open access database of promising indicators, namely, glycan structures that are presumably responsible for nutrient deficiency caused stress in plants (http://glycoplants.org).
Genesis1:11™ is a distant places plantation and forestation-supporting high-technology concept including but not limited to semi-capsuled ecosystems and various physical and precision software tools making it possible to inject microorganisms and to grow plant roots into extraterrestrial soils contributing to a sustainable future for the humankind in remote places (especially terraforming Mars) having extreme climatic and environmental conditions. In this paper main characteristics and utilization areas of Genesis1:11™ Rocket Capsule and technical specifications of Genesis1:11™ Rooting Pot are being discussed without claiming completeness, including a demonstration how a complex organism like a plant might provide a useful and simple host for large number of microbes.
