Abstract excerpt
In seed plants, ethylene is produced from 1-aminocyclopropane-1-carboxylic acid (ACC) by the enzyme ACC oxidase (ACO). Despite the critical role of ACO in ethylene biosynthesis, the ACO gene family has not been fully characterized in Arabidopsis (Arabidopsis thaliana). This study investigated the 5 ACO genes in Arabidopsis, revealing distinct tissue-specific and developmental expression patterns. Each ACO enzyme...
