摘要：

Arginine decarboxylase (ADC) cDNA from oat (Avena sativa L.) was introduced into rice (Oryza sativa L.) genome by an Agrobacterium-mediated transformation method. Expression of the ADC transgene under the control of an ABA-inducible promoter led to stress-induced upregulation of ADC activity and polyamine accumulation in transgenic rice plants. Second-generation (R1) transgenic rice plants showed an increase in biomass under salinity-stress conditions, as compared to the non-transformed control plants. (C) 2001 Elsevier Science Ireland Ltd.
