Abstract
Novel methods for the expression of non-native genes in flax seeds and the seeds of other plant species are provided. The methods involve the use of seed-specific promoters obtained from flax. Additionally provided are novel flax seed-specific promoters, chimeric nucleic acid constructs comprising novel flax seed-specific promoters, transgenic plant cells, transgenic plants and transgenic plant seeds containing novel flax seed-specific promoters. The promoters and methods are useful, for example, for altering the seed oil and protein composition in flax seed or other plant seeds.
