The results showed that the prime symptoms of the TPD include laticifer necrosis and cambium-like meristem formation that occurs around the necrotic laticifer in the inner bark.
Ground meristem The central region of the apical meristem from which the ground tissues of pith, cortex, medullary rays, and mesophyll differentiate. In root meristem it is also called periblem.
At the point where each leaf meets the stem, there's a bud, which is a new meristem that has the potential to grow into a branch and start producing its own stem and leaves.
