[Problem] Providing soybean including oleic acid that will exceed the heretofore developed high-oleic soybean without using gene engineering technology. [Means to Solve the Problem] The present invention provides a GmFAD2-1b gene loss of function mutation and a type of soybean that includes a GmGAD2-1b gene loss of function mutation.

Mutation that increases the oleic acid content in soybean oil and responsible gene thereof

The present invention provides a method of transforming common ice plant by gene transfer using a microorganism belonging to the genusand a method of producing a transformed common ice plant. The present invention also provides a stable transformed common ice plant.

Method of constructing transgenic ice plant

A soybean oil of a decreased content of polyunsaturated fatty acids is produced by hybridizing, selecting and raising a soybean mutant KK21 characterized by a gene having a sequence of base given by the sequence No. 1 of the sequence listing, a soybean mutant M23 characterized by deletion of a gene having a sequence of base given by the sequence No. 2 of the sequence listing, a soybean mutant M24 characterized by a gene having a sequence of base given by the sequence No. 3 of the sequence listing, a soybean mutant M5 characterized by a gene having a sequence of base given by the sequence No. 4 of the sequence listing, a soybean mutant J18 characterized by deletion of a gene having a sequence of base given by the sequence No. 5 of the sequence listing, and one or two kinds or more of these soybean mutants.

Soybean mutant strain and soybean oil therefrom

The present invention provides a method of producing diacylglycerol characterized by inactivating the function of a gene which encodes diacylglycerol acyltransferase having the function of enzymatically reacting with diacylglycerol to create triacylglycerol in a seed, so as to allow diacylglycerol to be accumulated in the seed.
