Regulation of metabolism by modification of the level of trehalose-6-phosphate by inhibition of endogenous trehalase level

摘要

A method of modification of the development and/or composition of cells, tissues, or organs in vivo in plants by inhibiting the level of an endogenous trehalase is provided. The cells, tissues, or organs have been genetically altered to comprise a DNA sequence encoding a trehalase inhibitor. The DNA sequence is capable of expressing an RNA that is at least partially complementary to an RNA produced by a DNA sequence encoding the endogenous trehalase. Alternatively, the DNA sequence comprises a DNA sequence which is identical to a DNA sequence encoding the endogenous trehalase. The modification is other than to increase production or accumulation of trehalose.
