Beschreibung
Zusammenfassung:	Provided are compositions comprising polynucleotides encoding glutamine synthetase (GS) polypeptides having improved properties, such as increased enzymatic activity and/or increased thermostability. Also provided are recombinant DNA constructs, plants, plant cells, seed, grain comprising the polynucleotides. Additionally, various methods of employing the polynucleotides in plants, such as methods for increasing GS activity in a plant, methods for increase seed protein content in a seed of a plant, and methods for increasing yield of a plant, are also provided herein. L'invention concerne des compositions comprenant des polynucléotides codant pour des polypeptides de glutamine synthétase (GS) présentant des propriétés améliorées, telles qu'une activité enzymatique accrue et/ou une thermostabilité accrue. L'invention concerne également des constructions d'ADN recombiné, des plantes, des cellules végétales, des graines, des céréales comprenant les polynucléotides. De plus, l'invention concerne également divers procédés d'utilisation des polynucléotides dans des plantes, tels que des procédés pour augmenter l'activité de GS dans une plante, des procédés pour augmenter la teneur en protéines de graines dans une graine d'une plante, et des procédés pour augmenter le rendement d'une plante.
