Abstract excerpt
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 F2 seedlings from crosses of adc1-1 and adc2-2 had the ADC1-/- ADC2-/- genotype. In addition, some abnormal seeds were observed...
