Biochem./physiol. Wirkung

Laccase katalysiert die Oxidation von phenolhaltigen Verbindungen, einschließlich Lignin, durch die Reduktion von Sauerstoff zu Wasser. Die Gegenwart von Vermittlern ermöglicht auch die Oxidation von nicht phenolhaltigen Verbindungen. Die primäre Funktion von Laccase ist der Abbau von Lignin in Pilzen.

Multicopper oxidases can act on a broad spectrum of phenolic and non-phenolic compounds. These enzymes include laccases, which are widely distributed in plants and fungi, and were more recently identified in bacteria. Here, we present the results of biochemical and

Increasing grain yields is a major focus of crop breeders around the world. Here we report that overexpression of the rice microRNA (miRNA) OsmiR397, which is naturally highly expressed in young panicles and grains, enlarges grain size and promotes panicle

Laccases, as early as 1959, were proposed to catalyze the oxidative polymerization of monolignols. Genetic evidence in support of this hypothesis has been elusive due to functional redundancy of laccase genes. An Arabidopsis double mutant demonstrated the involvement of laccases
