Abstract
Male-sterile plants can be produced by increasing the endogenous concentration of avidin in the plant tissues. This effect can be achieved by producing transgenic plants containing an expression vector in which a promoter is operably linked to a DNA sequence encoding avidin. Methods for restoring male fertility are disclosed. Additionally, methods for production of seeds with one or more desired grain traits are provided.
