succinylacetone | treatment of wild-type seedlings with succinylacetone mimicks the sscd1 phenotypes: the treated wild-type seedlings exhibit wilted leaves and slow-growth symptoms under long-day, these symptoms are more severe under short-day. The sscd1 mutant is more sensitive to succinylacetone than the wild type under long-day | Arabidopsis thaliana |

malfunction | an Arabidopsis thaliana short-day sensitive cell death1 (sscd1) mutant displays a spontaneous cell death phenotype under short-day conditions, disruption of FAH leads to cell death, phenotype overview. The spontaneous cell death phenotype of the sscd1 mutant is completely eliminated by further knockout of the gene encoding the putative homogentisate dioxygenase, which catalyzes homogentisate into maleylacetoacetate (the antepenultimate step) in the Tyr degradation pathway. Treatment of Arabidopsis wild-type seedlings with succinylacetone, an abnormal metabolite caused by loss of FAH in the Tyr degradation pathway, mimicks the sscd1 cell death phenotype | Arabidopsis thaliana |
metabolism | fumarylacetoacetate hydrolase hydrolyzes fumarylacetoacetate to fumarate and acetoacetate, the final step in the tyrosine degradation pathway that is essential for plant survival under short-day conditions | Arabidopsis thaliana |
