Rapid, Cf-9- and Avr9-Dependent Production of Active Oxygen Species in Tobacco Suspension Cultures
The tomato Cf-9 gene confers resistance to races of Cla-dosporium fulvum expressing the corresponding avirulence gene Avr9. The availability of transgenic tobacco lines carrying Cf-9, and the… Expand

Warm season N2-fixing legumes move fixed N from the nodules to the aerial portions of the plant primarily in the form of ureides, allantoin and allantoate, oxidation products of purines synthesized… Expand
Ureide metabolism during seedling development in French bean (Phaseolus vulgaris).
French bean (Phaseolus vulgaris) is a legume that transports most of the atmospheric nitrogen fixed in its nodules to the aerial parts of the plant as ureides. Changes in ureide content and in… Expand

An allantoate-degrading enzyme has been purified to electrophoretic homogeneity for the first time from a photosynthetic organism, the unicellular green algae Chlamydomonas reinhardtii. The… Expand
Purification and characterization of an l-amino-acid oxidase from Chlamydomonas reinhardtii
An l-amino-acid oxidase (EC 126.96.36.199) that catalyzes the oxidative deamination of twelve l-amino acids has been purified 21-fold and with 14% yield to electrophoretic homogeneity from Chlamydomonas… Expand
Urea is a product of ureidoglycolate degradation in chickpea. Purification and characterization of the ureidoglycolate urea-lyase.
A ureidoglycolate-degrading activity was analyzed in different organs of chickpea (Cicer arietinum). Activity was detected in all the tissues analyzed, but highest levels of specific activity were… Expand
Tissue abundance and characterization of two purified proteins with allantoinase activity from French bean (Phaseolus vulgaris).
Allantoinase (allantoin amidohydrolase, EC 188.8.131.52) catalyses the hydrolysis of allantoin to allantoic acid, a key reaction in the biosynthesis and degradation of ureides. This activity was… Expand
Cloning, characterization and mRNA expression analysis of PVAS1, a type I asparagine synthetase gene from Phaseolus vulgaris
Abstract. A gene encoding a putative asparagine synthetase (AS; EC 184.108.40.206) has been isolated from common bean (Phaseolus vulgaris L.). A 2-kb cDNA clone of this gene (PVAS1) encodes a protein of 579… Expand
Biochemical characterisation of an allantoate-degrading enzyme from French bean (Phaseolus vulgaris): the requirement of phenylhydrazine
In tropical legumes like French bean (Phaseolus vulgaris) or soybean (Glycine max), most of the atmospheric nitrogen fixed in nodules is used for synthesis of the ureides allantoin and allantoic… Expand
Purification and characterization of anl-amino-acid oxidase fromChlamydomonas reinhardtii
Anl-amino-acid oxidase (EC 220.127.116.11) that catalyzes the oxidative deamination of twelvel-amino acids has been purified 21-fold and with 14% yield to electrophoretic homogeneity fromChlamydomonas… Expand
