精氨酸脱羧酶 (ADC) 是拟南芥中催化多胺 (PA) 生物合成第一步的限速酶。我们在拟南芥中产生了两个 ADC 基因 (ADC1(-/-)ADC2(-/-)) 缺陷的双突变体,并检查了它们在种子发育中的作用。来自 adc1-1 和 ade2-2 杂交的 F-2 幼苗均不具有 ADC1(-/-)ADC2(-/-) 基因型。此外,ADC1(+/-)ADC2(-/-)和ADC1(-/-)ADC2(+/-)长角果中还观察到一些异常种子。无法从 ADC1(+/-)ADC2(-/-) 和 ADC1(-/-)ADC2(+/-) 植物中获得具有 ADC1(-/-)ADC2(-/-) 基因型的存活后代。这些结果表明 AtADC 基因是产生多胺所必需的,而多胺对于拟南芥种子的正常发育至关重要。 (C) 2005 年欧洲生化学会联合会。由 Elsevier B.V. 出版。保留所有权利。
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.
