| Abstract: | After growth for 26 d in water, rice seedlings were transferredto a medium containing 1 mM NH4Cl. The mRNA for NADH-glutamatesynthase was markedly increased in the roots within 3 h. Methioninesulfoximine completely inhibited this accumulation, suggestingthat NH4+ is not a direct inducer of this process. (Received July 11, 1997; Accepted September 10, 1997) |
