Cyanide metabolism in relation to ethylene production in plant tissues.
HCN is the putative product of C-1 and amino moieties of 1-aminocyclopropane-1-carboxylic acid (ACC) during its conversion to ethylene. In apple (Malus sylvestrus Mill.) slices or auxin-treated mungbean (Vigna radiata L.) hypocotyls, which produced ethylene at high rates, the steady state concentration of HCN was found to be no higher than 0.2 micromolar, which was too low to inhibit respiratio...
متن کاملEthylene production and enzyme induction in excised plant tissues.
Excising plant tissues has been found to increase the activity of phenylalanine ammonia-lyase (EC 4.1.3.5) (1, 4, 11, 12). This increase is probably due to de novo synthesis of this enzyme, since inhibitors of protein synthesis block the rise of PAL' activity (4, 11, 12). We suggested earlier (4) that the increase of PAL in gherkin hypocotyl segments was due to the release into the medium of re...
متن کاملImproving Alstroemeria Vase Life by Plant Extracts and 8-Hydroxyquinoline Sulfate
The effects of savory, caraway, and rose extracts and 8-HQS were studied on the vase life of Alstroemeria cut flowers. The plant extracts at three levels (10, 20, and 40 %), 8-HQS at three levels (100, 200, and 300 mg l-1), and control (distilled water) with 3 % sucrose were continuously applied on the basis of a Completely Randomized Design with three replications. It was f...
متن کاملThe Inhibition of Bacteriochlorophyll Biosynthesis in Rhodopseudomonas Spheroides by 8-hydroxyquinoline.
Granick (1948, 1950, 1961) has isolated different mutants of Chlorella which are unable to synthesize chorophyll and which accumulate magnesium protoporphyrin, magnesium vinyl phaeoporphyrin a5 and a monoester of magnesium protoporphyrin, presumed to be the monomethyl ester. Granick (1961) has proposed that these compounds are intermediates in chlorophyll biosynthesis, and it has been suggested...
متن کاملSALICYLIC ACID INHIBITION OF GERMINATION, ETHYLENE PRODUCTION AND RESPIRATION IN COCKLEBUR SEEDS
Salicylic acid (SA) inhibited germination of cocklebur (Xanthium pennsylvanicum Wlr), lower seeds, which are completely after-ripened and nondormant. SA also inhibited ethylene production during a pre-germination period of the seeds. Exogenous ethylene overcame the inhibtion of the seed germination by SA. Moreover, SA reduced respiration in pre-germinating whole seeds as well as excised axial...
