SAFFLOWER WITH ELEVATED GAMMA-LINOLENIC ACID

The present invention relates to compositions and methods for preparing gamma-linoleic acid (GLA) in safflower plants, particularly from seeds of safflower. Nucleic acid sequences and constructs encoding one or more fatty acid desaturase sequences are used to generate transgenic safflower plants tha...

Beschreibung
Zusammenfassung:	The present invention relates to compositions and methods for preparing gamma-linoleic acid (GLA) in safflower plants, particularly from seeds of safflower. Nucleic acid sequences and constructs encoding one or more fatty acid desaturase sequences are used to generate transgenic safflower plants that contain and express one or more of these sequences and produce high levels of GLA in safflower seeds. Provided are transgenic safflower plants and seeds that produce high levels of GLA. Additionally provided are oils produced from seeds of this invention. The invention also relates to methods of treating a variety of diseases including nervous system disorders, inflammatory conditions, cancer and cardiovascular disorders using the oils of this invention. La présente invention concerne des compositions et des procédés de préparation d'acide gamma-linolénique (AGL) dans des plants de safran, notamment dans des graines de safran. Des séquences d'acide nucléique et des constructions codant une ou plusieurs séquences de désaturase d'acide gras sont utilisées pour générer des plants de safran transgénique qui contiennent et expriment une ou plusieurs de ces séquences et produisent des taux élevés de AGL dans les graines de safran. Cette invention concerne des plants et des graines de safran transgénique qui produisent des taux élevés de AGL, des huiles produites à partir des graines selon l'invention, des méthodes de traitement de diverses maladies telles que les troubles du système nerveux, les états inflammatoires, le cancer et les troubles cardio-vasculaires au moyen des huiles selon l'invention.
