      abstract     = {Observed phenotypic variation in the lateral root branching
                      density (LRBD) in maize (Zea mays) is large (1–41 cm−1
                      major axis [i.e. brace, crown, seminal, and primary roots]),
                      suggesting that LRBD has varying utility and tradeoffs in
                      specific environments. Using the functional-structural plant
                      model SimRoot, we simulated the three-dimensional
                      development of maize root architectures with varying LRBD
                      and quantified nitrate and phosphorus uptake, root
                      competition, and whole-plant carbon balances in soils
                      varying in the availability of these nutrients. Sparsely
                      spaced (less than 7 branches cm−1), long laterals were
                      optimal for nitrate acquisition, while densely spaced (more
                      than 9 branches cm−1), short laterals were optimal for
                      phosphorus acquisition. The nitrate results are mostly
                      explained by the strong competition between lateral roots
                      for nitrate, which causes increasing LRBD to decrease the
                      uptake per unit root length, while the carbon budgets of the
                      plant do not permit greater total root length (i.e.
                      individual roots in the high-LRBD plants stay shorter).
                      Competition and carbon limitations for growth play less of a
                      role for phosphorus uptake, and consequently increasing LRBD
                      results in greater root length and uptake. We conclude that
                      the optimal LRBD depends on the relative availability of
                      nitrate (a mobile soil resource) and phosphorus (an immobile
                      soil resource) and is greater in environments with greater
                      carbon fixation. The median LRBD reported in several field
                      screens was 6 branches cm−1, suggesting that most
                      genotypes have an LRBD that balances the acquisition of both
                      nutrients. LRBD merits additional investigation as a
                      potential breeding target for greater nutrient acquisition.},
