Abstract
The invention relates to a plant that includes a transgene encoding a heterologous polypeptide conferring on plant expressing said polypeptide resistance to a hemipteroid sap-sucking insect. The transgene is also expressed in a plant component (such as a leaf). Typically, expression of such polypeptides deters feeding by insects such as psyllids (such as an Asian citrus psyllid, the African citrus psyllid, or the American citrus psyllid). Exemplary plants useful in the invention are citrus or solanaceous plants.
Claims36
A citrus plant comprising a transgene encoding a heterologous polypeptide conferring on said plant expressing said polypeptide resistance to a hemipteroid sap-sucking insect, wherein said transgene comprises a first regulatory gene involved in basal plant resistance.

A method of making a plant resistant to citrus greening, comprising introducing into a plant cell a transgene comprising a first regulatory gene involved in basal plant resistance;
- regenerating from said plant cell a transgenic plant expressing an insect inhibitory amount of a polypeptide encoded by said transgene;
- and demonstrating Asian citrus psyllid resistance as a property of said transgenic plant, thereby making the plant resistant to citrus greening.
