Abstract
A rice plant material having improved resistance against biotic stress factors, including rice brown planthopper and rice blast fungus, is achieved by overexpressing a FatB gene in the rice plant material to cause an increase in oil or triacylglycerol content in the rice plant material.
Claims43
A rice plant material, wherein the rice plant material exhibits overexpression of a FatB gene selected from the group consisting of FatB2, FatB6, FatB11 and a combination thereof.
A rice plant material, having a FatB gene adapted for overexpression of a FatB enzyme selected from the group consisting of FatB2 as defined in SEQ ID NO:
- 42 or 48, FatB6 as defined in SEQ ID NO:
- 44 or 50, FatB11 as defined in SEQ ID NO:
- 46 or 52, a FatB enzyme having at least 80% sequence identify with a FatB enzyme as defined in SEQ ID NO:
- 42, 44, 46, 48, 50 or 52, and a combination thereof.

(canceled)
A method of improving resistance of a rice plant material against a biotic stress, the method comprising overexpressing a FatB gene in the rice plant material.
The method according to claim 39 or 110, wherein
- the rice plant material is an Oryza sativa plant material or an O. glaberrima plant material;
- and
- overexpressing the FatB gene comprises introducing a CT-rich motif into a promoter of an O. sativa or O. glaberrima FatB gene.
