1-aminocyclopropane-1-carboxylic acid(ACC),produced from S-adenosyl-methionine(SAM)by ACC synthase(ACS),is oxidized by ACC oxidase(ACO)to produce the gaseous plant hormone ethylene in seed plants(Kende,1993).
Cysteine occupies a central position in plant metabolism because it is a reduced sulfur donor moleculeinvolved in the synthesis of essential biomolecules and defense compounds. Moreover, cysteine per se and its deriva...
In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolized by the β-cyanoalan...
The Arabidopsis FCLY gene encodes a specific farnesylcysteine (FC) lyase, which is responsible for the oxidative metabolism of FC to farnesal and cysteine. In addition, fcly mutants with quantitative decreases in FC...
