Abstract: Plant roots exist in a mutual interaction with the soil and organisms therein. To study root interactions among abiotic conditions, time and biotic factors we need to utilize various experimental systems. Non-invasive phenotyping quantifies growth parameters without affecting the observed plants. It facilitates studies ofgrowth rates and development of root system architecture (RSA) and links these to underlying molecular changes (phenomics). To do so we use several platforms of increasing complexity to address global challenges. Tackling the mandated reduction of N fertilizer, we show that Pseudomonas sp. in a gnotobiotic system, canhelp Brachypodium in N deficient conditions by changing RSA, supplying N, and adjusting protein and lipid abundances in inoculated plants after 3 weeks (Sanow et al., 2023, & unpublished). In collaboration with the Julich Plant Phenotyping Center, we make standard operating protocols usable with microbes. The effect oftemperature increase on RSA was investigated using the semi-open Grow Screen Agar system (Macabuhay et al., 2022) and showed that Parabulkoholderia sp. can mitigate the stress effects by changing root morphology, distribution, and increased growth rates. Algae as alternative fertilizers produce distinct root phenotype in Brachypodium in EcoFABs, and algal P is taken up (Mau et al., 2022). An ongoing study in wheat and soil-filled rhizotrons indicates that waste-water algal N is also available but nutrient uptake by the algae itself must be considered. Phenotypic, elemental, andmolecular results for wheat are available. Field work and non-invasive high-throughput root phenotyping intertwine in the Wish-Roots consortium tounderstand the effect of 20 wheat lines on soil health including microbiome.
