| Research Abstract |
In barley, low level of external nitrate is absorbed by high affinity transport system(HATS) which is composed of two proteins, HvNRT2 and HvNAR2. In this study, it was suggested that two proteins make complex in the isolated plasma membrane and co-localized at out most layer of the cells in root cortex. In addition, Bimolecular fluorescence complementation analysis showed that HvNRT2 and HvNAR2 interacts in the plasma membrane of the native plant cells.
