Arginine decarboxylase (ADC) is a rate-limiting enzyme that catalyzes the first step of polyamine (PA) biosynthesis in Arabidopsis thaliana. We generated a double mutant deficient in Arabidopsis two ADC genes (ADC1(-/-)ADC2(-/-)) and examined their roles in seed development. None of the F-2 seedlings from crosses of adc1-1 and ade2-2 had the ADC1(-/-)ADC2(-/-) genotype. In addition, some abnormal seeds were observed among the ADC1(+/-)ADC2(-/-) and ADC1(-/-)ADC2(+/-) siliques. Viable offspring with the ADC1(-/-)ADC2(-/-) genotype could not be obtained from the ADC1(+/-)ADC2(-/-) and ADC1(-/-)ADC2(+/-) plants. These results indicate that AtADC genes are required for production of polyamines that are essential for normal seed development in Arabidopsis. (C) 2005 Federation of European Biochemical Societies.
