      abstract     = {The functional implications of root cortical senescence
                      (RCS) are poorly understood. We tested the hypotheses that
                      RCS in barley (1) reduces the respiration and nutrient
                      content of root tissue; (2) decreases radial water and
                      nutrient transport; and (3) is accompanied by increased
                      suberization to protect the stele. Genetic variation for RCS
                      exists between modern germplasm and landraces. Nitrogen and
                      phosphorus deficiency increased the rate of RCS. Maximal
                      RCS, defined as the disappearance of the entire root cortex,
                      reduced root nitrogen content by $66\%,$ phosphorus content
                      by $63\%$ and respiration by $87\%$ compared with root
                      segments with no RCS. Roots with maximal RCS had 90, 92 and
                      $84\%$ less radial water, nitrate and phosphorus transport,
                      respectively, compared with segments with no RCS. The onset
                      of RCS coincided with $30\%$ greater aliphatic suberin in
                      the endodermis. These results support the hypothesis that
                      RCS reduces root carbon and nutrient costs and may therefore
                      have adaptive significance for soil resource acquisition. By
                      reducing root respiration and nutrient content, RCS could
                      permit greater root growth, soil resource acquisition and
                      resource allocation to other plant processes. RCS merits
                      investigation as a trait for improving the performance of
                      barley, wheat, triticale and rye under edaphic stress.},
