Methods for identifying compositions that alter wildtype expression of genes and proteins in a plant cell

摘要

A method for identifying compounds that selectively alter wildtype gene expression of a plant cell includes comparing a first expression profile from a plant cell or tissue contacted with a first test compound, an additional expression profile from the same plant cell or tissue contacted with an additional test compound, and a combined compound expression profile from the same plant cell or tissue contacted with the first test compound and the additional test compound, wherein each plant cell or tissue was contacted for a time sufficient to produce an alteration in the expression of at least one gene or gene product in the plant's cells or tissues; and wherein each expression profile comprises the expression level or pattern of at least one gene or gene product of the plant cell or tissue; and identifying a significant, unexpected alteration in the level or pattern of expression between the genes or gene products of the combined compound profile and those of the additive alterations of the first profile and the additional profile.
