Webpericycle [ pĕr ′ ĭ-sī′kəl ] A layer of nonvascular tissue that surrounds the vascular tissues in the roots of plants and is in turn surrounded by the endodermis. WebThe Arabidopsis root is a tractable system for the study of these processes because it has a simple organization of well-defined cell types that are generated through stereotyped cell divisions. Epidermis, cortex and endodermis surround the central stele, which consists of the pericycle and vascular tissue (Figure 1a) (Dolan et al., 1993). This ...

WebPlants may also have lateral roots that branch from the main tap root. The lateral roots originate from meristematic tissue in the pericycle, which is the outermost cell layer in the vascular cylinder in the center of the root (shown below).Once they have emerged, lateral roots then display their own primary growth, continually adding length to the lateral root. WebThe Pericycle is the outermost layer of the stele and innermost layer to the endodermis which is made up of parenchymatous cells. Pericycle plays an important role in lateral …
