Abstract

The effect from changing of the light spectra concerning the red-blue relation and the percentage in dark red (700 nm ± 30) on the building of the storage organ of vegetables were confirmed in several scientific works. This effect can be accompanied by an increased antioxidant concentration in the storage organ. In the field tests carried out by the IASP 2015 with kohlrabi and radish different light spectra were generated by transparent coloured foils (red, green, yellow and colourless). These light spectra were applied temporary only during certain development stages of the plants to induce plant reactions. The experiments revealed that this light impulse has above all an influence on the content of the antioxidants and the sugar concentration of the storage organs. Effects on the size of the organs (bulb of kohlrabi, root of radish) were insignificant. It became apparent that a change of the light spectrum makes sense in some development stages of the plants only. At the same time it was found that the coloured foils have different effects on the content of the antioxidants in the examined cultures. For example, the riboflavin content in the kohlrabi under the green foil was positively influenced. It was five times as much as in the control. In radish more riboflavin was synthesized under the red foil, it was 48% more than in the control. [ABSTRACT FROM AUTHOR]

4. Wechselwirkung von Riboflavin, Isoriboflavin und 2-Thiouracil auf die Induktion zweidimensionalen Wachstums von Farnprothallien.

Abstract

The inhibition of cell division induced by 2-thiouracil in prothallia of Dryopteris filix-mas and Anemia phyllitidis is reversed by riboflavin as well as by its physiological inactive analogue isoriboflavin. This antagonism is not due to an in vivo interaction as stated by Yeoh and Raghavan, but is rather caused by an in vivo sensibilisation of photo destruction of the inhibitor during early phase of spore germination. Riboflavin as well as isoriboflavin strongly inhibit cell divisions in the prothallia of Anemia phyllitidis. In spite of a significantly reduced growth rate no retardation of the onset of the 2-dimensional differentiation, as related to a critical cell number, can be stated in the Anemia prothallia.

Abstract

Die Lumazinsynthase ist das vorletzte Enzym der Biosynthese von Riboflavin. Sie katalysiert die Umsetzung der Edukte 3,4-Dihydroxy-2-butanon-4-phosphat und 5-Amino-6-ribitylamino-2,4(1H,3H)-pyrimidindion zu 6,7-Dimethyl-8-ribityllumazin. Im Rahmen dieser Arbeit wurden Lumazinsynthasen aus verschiedenen Mikroorganismen und Pflanzen auf ihre enzymkinetischen Parameter, sowohl im Single Turnover als auch im Steady State und auf ihre Quartärstrukturen untersucht. Daneben bietet sich das Enzym aus B. subtilis, aufgrund seiner 60meren, ikosaedrischen Struktur als Basis für die Entwicklung von Lumazinsynthasekapsiden an, die auf der Oberfläche verschiedene funktionelle Einheiten tragen. Es konnte anhand mehrerer Konstrukte gezeigt werden, dass diese als Abstandshalter, Koppler oder Vernetzer in biophysikalischen Systemen eingesetzt werden können. Lumazine synthase catalyses the penultimate step in the biosynthesis of riboflavin. The enzyme catalyses the formation of 6,7-dimethyl-8-ribityllumazine from the substrates 3,4-dihydroxy-2-butanone 4-phosphate and 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione. This work presents the analysis of steady state kinetics as well as single turnover kinetics and studies on the quartenary structure of lumazine synthases from several microorganisms and plants. In addition, the icosahedral structure of the lumazine synthase from B. subtilis offers a basis for the development of lumazine synthase capsids with a functionalised surface. Several mutants were shown to serve as spacer, coupler or cross linking agent in biophysical experiments.
