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

摘要

[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.

主权项

1. A modified soybean plant comprising:
a high oleic acid content; and loss of function mutations in GmFAD2-1a and GmFAD2-1b genes, wherein the loss of function mutations introduced into GmFAD2-1gene of SEQ ID NO: 1 comprise Gly103 to Val103 and Thr189 to Pro189 of SEQ ID NO: 2, and wherein the loss of function mutation of the GmFAD2-1a gene is identical to that of the GmFAD2-1a gene of M23 or KK21 line.
