Sufficient Conditions under Which a Transitive System Is Chaotic
Let (X, T ) be a topologically transitive dynamical system. We show that if there is a subsystem (Y, T ) of (X, T ) such that (X×Y, T ×T ) is transitive, then (X, T ) is strongly chaotic in the sense of Li and Yorke. We then show that many of the known sufficient conditions in the literature, as well as a few new results, are corollaries of this statement. In fact the kind of chaotic behavior w...
متن کاملAsparagine synthetase1, but not asparagine synthetase2, is responsible for the biosynthesis of asparagine following the supply of ammonium to rice roots.
Asparagine is synthesized from glutamine by the reaction of asparagine synthetase (AS) and is the major nitrogen form in both xylem and phloem sap in rice (Oryza sativa L.). There are two genes encoding AS, OsAS1 and OsAS2, in rice, but the functions of individual AS isoenzymes are largely unknown. Cell type- and NH4(+)-inducible expression of OsAS1 as well as analyses of knockout mutants were ...
متن کاملAsparagine biosynthesis in soybean nodules.
Asparagine biosynthesis in soybean (Glycine max [L.] Merr.) nodules has been difficult to demonstrate due to the poor conversion of suspected immediate precursors to asparagine and the instability of the key enzyme asparagine synthetase. The present study was designed to explore the effects of two ammonium assimilation inhibitors on the metabolism of (14)CO(2) to [(14)C]asparagine and to demons...
متن کاملAsparagine biosynthesis by the Novikoff Hepatoma isolation, purification, property, and mechanism studies of the enzyme system.
An enzyme system that catalyzes the conversion of Laspartate-W to asparagine-W in the presence of glutamine, ATP, and Mg++ has been purified 108-fold from a homogenate of the Novikoff hepatoma. ATP is converted to adenosine 5’-phosphate and inorganic pyrophosphate, and substitution of hydroxylamine for glutamine yields P-aspartylhydroxamate. The data suggest that the synthesis of asparagine in ...
