Design of a Seed-Specific Chimeric Promoter with a Modified Expression Profile to Improve Seed Oil Content.

ABSTRACT: Increasing the yield of plant oil is an important objective to meet the demand for sustainable resources and energy. Some attempts to enhance the expression of genes involved in oil synthesis in seeds have succeeded in increasing oil content. In many cases, the promoters of seed-storage protein genes have been used as seed-specific promoters. However, conventional promoters are developmentally regulated and their expression periods are limited. We constructed a chimeric promoter that starts to express in the early stage of seed development, and high-level expression is retained until the later stage by connecting the promoters of the biotin carboxyl carrier protein 2 (BCCP2) gene encoding the BCCP2 subunit of acetyl-CoA carboxylase and the fatty acid elongase 1 (FAE1) gene from Arabidopsis
