Green light for the cell cycle.

In recent years, considerable progress has been made in unraveling the control mechanisms operating on the plant cell cycle and most of the key regulators have now been identified, including cyclin-dependent kinases (CDKs), cyclins, CDK-inhibitory proteins, the WEE kinase and proteins of the retinoblastoma-related protein (RBR)/E2F/DP pathway. The review discusses recent developments in our und...

Light Regulates the Cell Cycle in Zebrafish

The timing of cell proliferation is a key factor contributing to the regulation of normal growth. Daily rhythms of cell cycle progression have been documented in a wide range of organisms. However, little is known about how environmental, humoral, and cell-autonomous factors contribute to these rhythms. Here, we demonstrate that light plays a key role in cell cycle regulation in the zebrafish. ...

Green light for selected baby

Zain Hashmi is a three-year-old little boy from northern England with big brown eyes and a fatal disease, beta thalassaemia major. As his bone marrow is unable to produce sufficient numbers of red blood cells, he needs regular transfusions and is unlikely to survive for long unless transplanted with suitable stem cells. These could come from the bone marrow of a donor with matching tissue type,...

The effect of light on the tricarboxylic Acid cycle in green leaves: I. Relative rates of the cycle in the dark and the light.

Excised green leaves of mung bean (Phaseolus aureus L. var. Mungo) were used to determine the effect of light on the rate of endogenous respiration via the tricarboxylic acid cycle. Illumination with white light at an intensity of 0.043 gram calories cm(-2)min(-1) (approximately 8600 lux) of visible radiation (400-700 nm) gave a rate of apparent photosynthesis, measured as net CO(2) uptake, of ...

Regulation of the Chlamydomonas cell cycle by light and dark

By growing cells in alternating periods of light and darkness, we have found that the synchronization of phototrophically grown Chlamydomonas populations is regulated at two specific points in the cell cycle: the primary arrest (A) point, located in early G1, and the transition (T) point, located in mid-G1. At the A point, cell cycle progression becomes light dependent. At the T point, completi...
