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2023, $\&$ unpublished).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. (OK is funded by
