Plant Growth: Jogging the Cell Cycle with JAG
In yeast, cell growth and division are coordinated by size checkpoints in the cell cycle. Recent work suggests that a similar mechanism acts in plant meristems to limit cell-size variation.
متن کاملPlant growth: Roots in the cell cycle
Overexpression in transgenic plants of a B-type cyclin--thought to regulate cell-cycle progression to mitosis--causes structures such as roots to grow faster than normal, indicating that the rate of cell division may be a constraint on plant growth.
متن کاملThe plant cell cycle.
Cell division in plants is controlled by the activity of cyclin-dependent kinase (CDK) complexes. Although this basic mechanism is conserved with all other eukaryotes, plants show novel features of cell-cycle control in the molecules involved and their regulation, including novel CDKs showing strong transcriptional regulation in mitosis. Plant development is characterized by indeterminate growt...
متن کاملUpdate on Plant Cell Cycle Control Switching the Cell Cycle. Kip-Related Proteins in Plant Cell Cycle Control
During the development of multicellular organisms, many different cell types are created. These display characteristic cell cycle programs that can radically change during the organism’s lifetime (Jakoby and Schnittger, 2004; Fig. 1). Usually, in younger and less differentiated tissues, a proliferative cell cycle mode occurs. In this mitotic cell cycle program, DNA replication (also known as th...
متن کاملGrowth during the cell cycle.
During the cell cycle, major bulk parameters such as volume, dry mass, total protein, and total RNA double and such growth is a fundamental property of the cell cycle. The patterns of growth in volume and total protein or RNA provide an "envelope" that contains and may restrict the gear wheels. The main parameters of cell cycle growth were established in the earlier work when people moved from ...
