Research Abstract |
Molecular mechanisms underlying the sensing and signaling of available nitrogen have been unclear in plants. In this study, two important findings were obtained as described below. OsACR9 may be assembled into the glutamine-signal transduction system on ammonium assimilation in roots and re-utilization of recycling nitrogen in young organs of rice plants. OsACTPK1 could be involved in the regulation of ammonium absorption and assimilation in roots of rice seedlings grown under sufficient or excess ammonium conditions.
