Pericycle cells are
WebThe pericycle is a thick, layered tissue. It is outside the vascular strand and is located inside the endodermis. It is heterogeneous in nature. Parenchyma and sclerenchyma fibres both make up its structure. Sclerenchyma appears as semilunar or … WebThe pericycle is a vital layer which typically indicates the outer boundary of the vascular strand. In the early root, the pericycle cells have thin walls and are parenchymatous. It contributes to the formation of the vascular cambium. It is where the cork cambium also grows. The pericycle serves as the genesis of all lateral roots.

WebRecent evidence showed that the priming of pericycle cells for LR initiation takes place in the basal meristem (De Smet et al., 2007). We observed that the increase in expression of TIR1 takes place mainly in the basal part of the root, suggesting that a higher rate of pericycle cell priming might be occurring under low Pi conditions.
