Protein-phosphatase inhibitors block root hair growth and alter cortical cell shape of Arabidopsis roots

Emerging evidence suggests that protein phosphatases play an important role in the growth and development of higher plants. We report here on the effects of okadaic acid and calyculin-A, two specific and potent inhibitors of the type-1 and type-2A families of serine/ threonine protein phosphatases, on the growth and development of Arabidopsis thaliana L… CONTINUE READING
