      abstract     = {One of the big challenges facing humanity is securing food
                      and feed for future generations in a sustainable bioeconomy.
                      The way fertilizer is used today aims at high yields without
                      adequately considering the needs of plants and the
                      preservation of our environment. The microalgae Chlorella
                      vulgaris has been successfully used as a vector system to
                      recycle phosphorus. Our group found additionally that C.
                      vulgaris can fertilize wheat and modify the root
                      architecture. The underlying mechanisms have not yet been
                      investigated, and as a consequence, we hypothesize that: (1)
                      nutrients from algae are available to wheat (Triticum
                      aestivum L.) root uptake; (2) roots respond to algae
                      fertilizer with changes in root architecture and morphology
                      that are different to conventional fertilizer; and (3)
                      active response of roots to algal nutrients is reflected in
                      an alternate mode of nutrient uptake. We are analyzing
                      single plants in highly controlled microenvironments that
                      allow the direct observation of morphological changes at the
                      root micro- and macroscales. Simultaneously, we quantify
                      changes in the phosphate pools released and transformed from
                      algal components into the medium, their uptake from the
                      medium, and their incorporation into the plant. These
                      dynamics will allow the identification of the fertilizing
                      phosphate components of the algal biomass. Their separation
                      into different organic and inorganic fractions will allow
                      the identification of the specific components available to
                      root uptake. Effects of components on roots and the
                      plant’s nutrition will be assessed by metabolomics. We are
                      using the genetic model for wheat, Brachypodium distachyon,
                      because it is suited to phenotyping, genotyping and
                      interpretation of metabolomics. A better understanding of
                      the interface between algal nutrients and the root may
                      enable future agricultural applications with sustainable use
                      of algal biomass after it has been mined for other valuable
                      compounds.},
