Transport and Metabolism of 1-Aminocyclopropane-1-carboxylic Acid in Sunflower (Helianthus annuus L.) Seedlings.
Transport and metabolism of [2,3-(14)C] 1-aminocyclopropane-1-carboxylic acid (ACC) from roots to shoots in 4-day-old sunflower (Helianthus annuus L.) seedlings were studied. [(14)C]ACC was detected in, and (14)C(2)H(4) was evolved from, shoots 0.5 hours after [(14)C]ACC was supplied to roots. Ethylene emanation from the shoots returned to normal levels after 6 hours. The roots showed a similar...
متن کاملLipid peroxidation forms ethylene from 1-aminocyclopropane-1-carboxylic acid and may operate in leaf senescence.
An enzyme system is described which oxidizes 1-aminocyclopropane-1-carboxylic acid (ACC) to ethylene under physiological conditions. It comprises linoleic acid, pyridoxal phosphate, manganese, and lipoxygenase (linoleate:oxygen oxidoreductase, EC 1.13.11.12). It requires oxygen and is specific for manganese; it can operate but only with greatly reduced yield in the absence of pyridoxal phosphat...
متن کاملSynthesis of Deuterium - labeled 1 - Aminocyclopropane - 1 - carboxylic Acid
[ ZH2 IACC) ; 1-amino [ 2R, 3E-2H2] cyc lopropaneIcar boxy 1 ic acid (trans-[zH2]ACC) : and l-amino[2,2.3.3-~H~]cyclopropane1-carboxylic acid are described. The [2,2-2H2]and [2,2,3.3-2H4]ACC compounds were prepared from the appropriately deuterated 2-bromoethanol 4-methylbenzenesulfonates by reaction with ethyl isocyanoacetate and two moles oE sodium hydride. The transr2H2]ACC and &[2H2]ACC wer...
متن کاملEthylene Production and 1-Aminocyclopropane-1-Carboxylic Acid Conjugation in Thermoinhibited Cicer arietinum L. Seeds.
The effect of supraoptimal temperatures (30 degrees C, 35 degrees C) on germination and ethylene production of Cicer arietinum (chick-pea) seeds was measured. Compared with a 25 degrees C control, these temperatures inhibited both germination and ethylene production. The effect of supraoptimal temperatures could be alleviated by treating the seeds with ethylene. It was concluded that one effect...
متن کاملIsolation and Molecular Characterization of 1-Aminocyclopropane-1-carboxylic Acid Synthase Genes in Hevea brasiliensis
Ethylene is an important factor that stimulates Hevea brasiliensis to produce natural rubber. 1-Aminocyclopropane-1-carboxylic acid synthase (ACS) is a rate-limiting enzyme in ethylene biosynthesis. However, knowledge of the ACS gene family of H. brasiliensis is limited. In this study, nine ACS-like genes were identified in H. brasiliensis. Sequence and phylogenetic analysis results confirmed t...
