Synthesis 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 کاملInterference of phenolic compounds with the 1-aminocyclopropane-1-carboxylic Acid assay.
The yields of ethylene from endogenous and exogenous 1-aminocyclo-propane-1-carboxylic acid (ACC) in avocado (Persea Americana Mill.) fruit pedicel extracts were very low when assayed by the method of Lizada and Yang (1979 Anal Biochem 100: 140-145). Addition of phenolic compounds, which are present in avocado tissues, to the assay mixture significantly reduced the conversion efficiency of ACC ...
متن کاملEthylene Evolution following Treatment with 1-Aminocyclopropane-1-carboxylic Acid and Ethephon in an in Vitro Olive Shoot System in Relation to Leaf Abscission.
1-Aminocyclopropane-1-carboxylic acid (ACC) supplied via the cut base of detached olive shoots caused a burst of ethylene from leaves, but other cyclopropanes tested did not exhibit this effect. Ethephon (ET) and another ethylene-releasing compound caused a prolonged increase in ethylene evolution. ACC had only a very limited effect on leaf abscission regardless of concentration, whereas shoots...
متن کاملPotamogeton pectinatus Is Constitutively Incapable of Synthesizing Ethylene and Lacks 1-Aminocyclopropane-1-Carboxylic Acid Oxidase.
A highly sensitive laser-driven photoacoustic detector responsive to [less than or equal to]2.1 nmol m-3 ethylene (50 parts per trillion [v/v]) was used for ethylene analysis. Dark-grown plants of Potamogeton pectinatus L. growing from small tubers made no ethylene. Exposure of shoots to white light, wounding, submergence in water followed by desubmergence, partial oxygen shortage, indole aceti...
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...
