MCS in roots

MCS in roots

3 images in one

Called multiseriate cortical sclerenchyma by the researchers — or MCS — the phenotype is characterized by small cells with thick walls just beneath the surface of the roots, as shown by these images captured by the researchers using laser ablation tomography. Roots with the MCS genotype have a greater concentration of lignin — an organic polymer that lends rigidity.
