摘要： Described is a technology, such as implemented in a computational software program, by which a minimal polynomial is efficiently determined for a radical expression over the ring Z of integer numbers or the ring Q of rational numbers. The levels of the radical are grouped into a level permutation group that is used to find a level permutation set. An annihilation polynomial is found based upon the level permutation set. The annihilation polynomial is factored, and a selection mechanism selects the minimal polynomial based upon the annihilation polynomial's factors.

摘要： Described is a technology, such as implemented in a computational software program, by which a minimal polynomial is efficiently determined for a radical expression based upon its structure of the radical expression. An annihilation polynomial is found based upon levels of the radical to obtain roots of the radical. A numerical method performs a zero test or multiple zero tests to find the minimal polynomial. In one implementation, the set of roots corresponding to a radical expression is found. The annihilation polynomial is computed by grouping roots of the set according to their conjugation relationship and multiplying factor polynomials level by level. A selection mechanism selects the minimal polynomial based upon the annihilation polynomial's factors.

摘要： Provided is a peptide, peptide multimer or fusion protein containing such peptide which binds to the gut of sap-sucking insects, e.g., aphids. When bound, this peptide inhibits the binding of targeted virus to the insect gut. When this peptide or tandem repeat peptide is expressed (or is expressed as part of a fusion protein) in the fluids of transgenic plants, it is taken up by the insect with the sap, binds to gut receptors and thereby inhibits transmission of the virus from plant to plant via the insect vector. Thus, the use of such transgenic plants blocks or reduces the transmission of the targeted virus and others which share the peptide binding site within the insect gut among plants susceptible to the virus and thereby reduces losses due to viral infection.

摘要： Provided are chimeric aphicidal and insecticidal toxin proteins comprising peptide, peptide multimer or fusion protein containing such peptide which binds to the gut of sap-sucking insects, e.g., aphids, thrips, leafhoppers, or other target interest. When bound, this peptide mediates the binding of the chimeric aphicidal or other insecticidal protein to the target insect gut. Also described are coding sequences, vectors, and transgenic plants genetically modified to contain and express such aphicidal or insecticidal proteins. Thus, the use of such transgenic plants reduces economic loss due to feeding by the target insect and also reduces loss due to plant diseases spread by the target insect.
