Abstract
The invention relates to improved Brassica species, including Brassica juncea, improved oil and meal from Brassica juncea, methods for generation of such improved Brassica species, and methods for selection of Brassica lines. Further embodiments relate to seeds of Brassica juncea comprising an endogenous oil having increased oleic acid content and decreased linolenic acid content relative to presently existing commercial cultivars of Brassica juncea, seeds of Brassica juncea having traits for increased oleic acid content and decreased linolenic acid content in seed oil stably incorporated therein, and one or more generations of progeny plants produced from said seeds.
Claims14
An unmodified Brassica juncea oil with a fatty acid content comprising at least 70.0% oleic acid by weight and less than 3.0% linolenic acid by weight, wherein the oil comprises a polynucleotide selected from the group consisting of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:24, SEQ ID NO:26, SEQ ID NO:28, SEQ ID NO:30, SEQ ID NO:32, SEQ ID NO:34, SEQ ID NO:36, and SEQ ID NO:38.
An oil extracted from the seeds of a Brassica juncea plant that is genetically stabilized for an endogenous fatty acid content comprising at least 70.0% oleic acid by weight and less than 3.0% linolenic acid by weight,
- wherein the oil comprises a polynucleotide selected from the group consisting of SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:24, SEQ ID NO:26, SEQ ID NO:28, SEQ ID NO:30, SEQ ID NO:32, SEQ ID NO:34, SEQ ID NO:36, and SEQ ID NO:38.
A transgenic Brassica juncea plant whose seeds have an endogenous fatty acid content comprising between about 70% and 78% oleic acid by weight and between about 2% and 3% linolenic acid by weight, wherein the plant contains a fad2 or fad3 allele encoding a mutant delta-12 fatty acid desaturase.
