      abstract     = {Background and AimsRoot cortical senescence (RCS) is a
                      poorly understood phenomenon with implications for
                      adaptation to edaphic stress. It was hypothesized that RCS
                      in barley (Hordeum vulgare L.) is (1) accelerated by
                      exogenous ethylene exposure; (2) accompanied by differential
                      expression of ethylene synthesis and signalling genes; and
                      (3) associated with differential expression of programmed
                      cell death (PCD) genes.MethodsGene expression of root
                      segments from four barley genotypes with and without RCS was
                      evaluated using quantitative real-time PCR (qRT-PCR). The
                      progression of RCS was manipulated with root zone ethylene
                      and ethylene inhibitor applications.Key ResultsThe results
                      demonstrate that ethylene modulates RCS. Four genes related
                      to ethylene synthesis and signalling were upregulated during
                      RCS in optimal, low nitrogen and low phosphorus nutrient
                      regimes. RCS was accelerated by root zone ethylene
                      treatment, and this effect was reversed by an ethylene
                      action inhibitor. Roots treated with exogenous ethylene had
                      35 and 46 $\%$ more cortical senescence compared with the
                      control aeration treatment in seminal and nodal roots,
                      respectively. RCS was correlated with expression of two
                      genes related to programmed cell death (PCD).ConclusionsThe
                      development of RCS is similar to root cortical aerenchyma
                      formation with respect to ethylene modulation of the PCD
                      process.},
