Abstract : |
The relationship between light and NR synthesis was studied in excised Lentil leaves. In light, there was about 10 to 12 fold increases in the NR level as compared to the dark (as a controls). In the dark, a significant amount of intracellular nitrate was detected, but there was very little NR activity. Sucrose did not have any effect on NR synthesis. Measurement of the decay rates of NR in the dark and light showed that NR activity disappeared faster in light than in the dark. Exposure to short duration`s of blue, red and white light caused an increase in the NR synthesis. So the process of nitrate reduction influences NR synthesis., |
