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 کاملXylem Transport of 1-Aminocyclopropane-1-carboxylic Acid, an Ethylene Precursor, in Waterlogged Tomato Plants.
Waterlogging is known to cause an increase in ethylene synthesis in the shoot which results in petiole epinasty. Evidence has suggested that a signal is synthesized in the anaerobic roots and transported to the shoot where it stimulates ethylene synthesis. Experimental data are presented showing that 1-aminocyclopropane-1-carboxylic acid (ACC), the immediate precursor of ethylene, serves as the...
متن کاملEthylene synthesis regulated by biphasic induction of 1-aminocyclopropane-1-carboxylic acid synthase and 1-aminocyclopropane-1-carboxylic acid oxidase genes is required for hydrogen peroxide accumulation and cell death in ozone-exposed tomato.
We show that above a certain threshold concentration, ozone leads to leaf injury in tomato (Lycopersicon esculentum). Ozone-induced leaf damage was preceded by a rapid increase in 1-aminocyclopropane-1-carboxylic acid (ACC) synthase activity, ACC content, and ethylene emission. Changes in mRNA levels of specific ACC synthase, ACC oxidase, and ethylene receptor genes occurred within 1 to 5 h. Ex...
متن کامل1-aminocyclopropane-1-carboxylic acid (ACC) in plants: more than just the precursor of ethylene!
Ethylene is a simple two carbon atom molecule with profound effects on plants. There are quite a few review papers covering all aspects of ethylene biology in plants, including its biosynthesis, signaling and physiology. This is merely a logical consequence of the fascinating and pleiotropic nature of this gaseous plant hormone. Its biochemical precursor, 1-aminocyclopropane-1-carboxylic acid (...
متن کاملThe involvement of 1-aminocyclopropane-1-carboxylic acid synthase isogene, Pp-ACS1, in peach fruit softening.
Ethylene promotes fruit ripening, including softening. The fruit of melting-flesh peach (Prunus persica (L). Batsch) cultivar 'Akatsuki' produces increasing levels of ethylene, and the flesh firmness softens rapidly during the ripening stage. On the other hand, the fruit of stony hard peach cultivars 'Yumyeong', 'Odoroki', and 'Manami' does not soften and produces little ethylene during fruit r...
