Review of Short Phrases and Links

    This Review contains major "Pericycle"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. The pericycle is a cylinder of parenchyma cells that lies just inside the endodermis and is the outer most part of the stele (biology) of plants. (Web site)

Pericycle

  1. The outer part, known as the pericycle, surrounds the actual vascular tissue.
  2. In roots, the cork cambium originates in the pericycle, a component of the vascular cylinder.
  3. As the stele increases in diameter, the cortex, pericycle and endodermis are lost.
  4. In plants undergoing secondary growth, the pericycle contributes to the vascular cambium often diverging into a cork cambium. (Web site)
  5. Cork cambium forms from the pericycle of the stele and produces the periderm, which becomes secondary dermal tissue. (Web site)

Root

  1. C, cortex; En, endodermis; Ep, epidermis; L, lateral root cap; p, pericycle. (Web site)
  2. In the enhancer trap line J0121, GAL4 expression is specific to 2–3 root pericycle cell files adjacent to the xylem poles. (Web site)
  3. A lateral root forms as a clump of cells in the pericycle, then elongates and pushes through the cortex until it emerges from the primary root. (Web site)

Transport

  1. The final step from the cytoplasm of the pericycle cells to the xylem is probably accomplished once again by active transport. (Web site)
  2. This supposition implies that high auxin levels in the pericycle would be actively reinforced by the locally increased auxin transport potential. (Web site)

Pericycle Cells

  1. Therefore, lateral root initiation can only take place when cell cycle activation is accompanied by cell fate respecification of pericycle cells. (Web site)
  2. Finally, the LIN1 gene may limit the ability of auxin to stimulate pericycle cells. (Web site)
  3. Some unknown signal triggers groups of pericycle cells to reenter the cell cycle and become lateral root founder cells. (Web site)

Xylem

  1. In Arabidopsis thaliana, lateral root founder cells originate from pericycle cells adjacent to xylem poles.
  2. GFP expression in J0121 root tissues occurs in mature xylem-pole pericycle cells, i.e. (Web site)
  3. In addition to the genes preferentially expressed in the wild-type pericycle, 73 genes were preferentially expressed in rum1 pericycle cells. (Web site)
  4. In Arabidposis, the pericycle cells in this position are marked by expression of CyclinA2 (Beeckman et al., 2001). (Web site)
  5. Auxin from the aerial tissues travels to the root and induces cell division in certain pericycle cells. (Web site)
