Concentration Gradients of trans-Zeatin Riboside and trans-Zeatin in the Maize Stem: Measurement by a Specific Enzyme Immunoassay.
A sensitive, specific enzyme immunoassay (EIA) for trans-zeatin riboside (ZR) and trans-zeatin (Z) in the 0.3 to 30 picomole range has been described. The reliability of the method for measuring ZR + Z in partially purified extracts of Zea mays L. tissues was verified by highperformance liquid chromatography. EIA measurements showed that there was a concentration gradient of ZR + Z along the le...
متن کاملEffects of zeatin riboside, mannitol and heat stress on eggplantn (Solanum melongena L.) anther culture
In this research, the effects of zeatin riboside (0.6, 0.8, 1, 1.2 and 1.4 mg l-1), duration of heat stress of 35 °C (6, 8, 10 and 12 days) and mannitol (0, 10, 20, 30 and 40 mg l-1) on anther culture of four eggplant cultivars were investigated in independent experiments. These experiments were performed according to a factorial arrangement in a randomized complete blocks design layout. The re...
متن کاملInfluence of Endogenous Cytokinins on Reverse Mobilization in Cotyledons of Cicer arietinum L: Reproduction of Endogenous Levels of Total Cytokinins, Zeatin, Zeatin Riboside, and Their Corresponding Glucosides.
The embryonic axis plays an essential role in the mobilization of the main reserves of the cotyledons of seeds of Cicer arietinum L. cv Castellana. This control by the axis of the metabolism of the storage products of the cotyledons largely takes place through the cytokinins, which are transported from the embryonic axis to the cotyledons where the mobilization of reserves begins. The principal...
متن کاملComparative Activity of Isomers of Zeatin and Ribosyl-Zeatin on Funaria hygrometrica.
The activities of isomers of zeatin, ribosyl-zeatin, and 6-(gamma,gamma-dimethylallylamino) purine (i(6)Ade) on the moss Funaria hygrometrica are compared by measuring the ability of the cytokinins to induce callus or gametophores. The cis- and trans-ribosyl-zeatins were inactive, and therefore this kind of bioassay cannot be used as evidence for the presence or absence of a cytokinin in tests ...
متن کاملThe rms7 Mutant of Pea Has Elevated Indole-3-Acetic Acid Levels and Reduced Root-Sap Zeatin Riboside Content
Rmsl i s one of the series of five ramosus loci in pea (Pisum sativum 1.) in which recessive mutant alleles confer increased branching at basal and aerial vegetative nodes. Shoots of the nonallelic rms l and rms2 mutants are phenotypically similar in most respects. However, we found an up to 40-fold difference in root-sap zeatin riboside ([9R]Z) concentration between rms l and rms2 plants. Comp...
