Significance Multiseriate cortical sclerenchyma (MCS) is a root anatomical phenotype with utility in environments mechanical impedance. The MCS characterized by small cells thick walls outer tissue. Genotypes were associated greater lignin concentration, tensile strength, and tip bending force compared to non-MCS genotypes. improved depth plant growth under impedance the greenhouse field. heritable genetically controlled. identification of phenes their genetic control may be an important consideration for breeders improvement crop cultivars enhanced edaphic stress tolerance.
