Multiseriate cortical sclerenchyma enhance root penetration in compacted soils

Multiseriate cortical sclerenchyma (MCS) is a root anatomical phenotype in maize, wheat, and other cereals with utility in environments with mechanical impedance.

Metrics of phenes are more reliable, stable, and robust descriptions of root architecture than are estimates of phene aggregates.
