Patent number: 5869719Abstract: The present invention reveals that biotin biosynthesis in a plant is enhanced when the level of one or more of the enzymes in the plant biotin biosynthetic pathway is increased. Based upon this revelation, methods that increase the level of one or more biotin biosynthetic enzymes in plant tissue are provided as a means for achieving enhanced levels of biotin in plant tissue. In particular, a method is provided for enhancing biotin levels by introducing into plant tissue a chimeric gene capable of expressing a biotin biosynthetic enzyme such as biotin synthase. Thus, transgenic plant tissue, including whole plants, having enhanced levels of biotin is likewise provided.Type: GrantFiled: April 30, 1997Date of Patent: February 9, 1999Assignee: Novartis Finance CorporationInventor: David A.

Patent number: 5824542Abstract: The present invention provides a dual method for producing male-sterile plants. Two genetically transformed plants, parents 1 and 2 are crossed to obtain male-sterile offspring. Parent 1 is transformed with an expression cassette comprising a nucleotide sequence encoding an anther-specific promoter which is operably linked to a nucleotide sequence encoding a transactivator. Parent 2 is transformed with an expression cassette comprising a target nucleotide sequence, which is capable of being activated by the transactivator, operably linked to a nucleotide sequence which encodes RNA or a polypeptide which will disrupt the formation of viable pollen. Therefore, crossing parent 1 with parent 2 results in male-sterile offspring. The male-sterile plants are useful for producing hybrid seed.The invention also provides compositions and methods for high level expression of a coding region of interest in a plant.Type: GrantFiled: May 23, 1995Date of Patent: October 20, 1998Assignee: Novartis Finance CorporationInventors: Lyle D.
