A chimeric expression per motors of commelina yellow mottle virus and cassava vein mosaic virus

摘要

The present invention relates to chimeric promoters comprising at least one nucleic acid sequence, derived from a first plant promoter comprising a plant vascular expression promoter region, said plant vascular expression promoter region being replaced with a nucleic acid sequence, derived from a second plant promoter and comprising a plant green tissue expression promoter region. The invention also relates to a process for manufacturing these promoters, and expression cassettes, vectors, and transgenic plants and seeds containing them.
