Hanstein proposed a controversial "histogen" theory of this structure. Cells in the L1 division of this structure only divide anticlinally. The lower border of this structure is formed by the rib zone. The YUCCA family of flavin monooxygenases regulates the TAM biosynthetic pathway in this tissue to produce its most important signaling molecule.

In these dome-shaped structures, the corpus is covered by a thin layer called the tunica. CLAVATA restricts the size of this structure by acting in the layer of cells below it to restrict WUSCHEL. Phyllotaxy is determined in this tissue by the pattern of emergence of leaf primordia. In a phenomenon known as its "dominance", this structure restricts the growth of axillary structures by secreting auxins. For 10 points, name this collection of plant stem cells found at shoot and root tips.
