دانلود Cyclin-Dependent Kinases and Cell Division in Plants—The Nexus

Abstract

Cell division is one of the most conspicuous features of life, and thus several elements of the control of cell division are common to both prokaryotes and eukaryotes (Amon, 1998; Leatherwood, 1998). The degree of evolutionary conservation is especially striking among eukaryotes, where progression through the successive phases of the cell cycle (S, G2, M, and G1) in species as diverse as yeast and humans is driven by a common class of heterodimeric serine/threonine protein kinases. These kinases consist of a catalytic subunit, termed cyclin-dependent kinase (CDK), and an activating subunit, cyclin reviewed in Nigg, 1995.
