| Research Abstract |
In this study, we isolated one of nitrate reductase (NR), one of nitrite reductase (NiR) and five nitrate transporter (CsNRT) genes from tea plant.
The transcript levels of these genes in tea plant cultivated under different nitrogen nutrient conditions were increased with increasing nitrate concentration and decreased with increasing ammonia concentration. In addition, it was found that nitrate absorption activity of tea is lower than ammonia.
These results suggested that the causes of low nitrate absorption and assimilation activity in tea plant might be due to the transcriptional processes and the nitrate transport into shoots is limited.
