Abstract
... The development of the suspensor in Sedum acre L. and S. hispanicum L. was investigated using cytochemical methods and light microscopy. After the first division of the zygote, two cells of unequal size are formed: the large basal cell (BC) and the smaller apical one. The basal cell grows enormously ...

... Rho, Rac, and Cdc42 have all been reported to regulate the JNK and MAP kinase cascades (Hall, 1998). This means that they regulate gene transcription in even a more direct way than through their effects on adhesion complexes (Hall, 1998). Evidence for other mechanisms in which Rho family proteins di ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
