Abstract
In higher plants, metabolism of sugar (C) and nitrogen (N) is regulated each other. Therefore it is suggested the existence in C/N regulator which senses and controls metabolism with relative amount of C and N (C/N balance).
To clarify the regulator, we isolated C/N response mutant ssv1-D (super survival 1-D) in which SSV1 gene was overexpressed. The mutant enables to survive under high-sugar / low-nitrogen conditions while wild-type does not.
The SSV1 gene belongs to Arabidopsis ATL family. Thus functional study on ATL gene family in C/N response was examined. Detailed characterizations of ATL family will be reported.
