摘要：
The invention relates to isolated and characterized full-length plant promoters from Eucalyptus. The promoters regulate expression of the cellulose synthase (CesA) family of genes, which are involved in wood and fibre formation in trees. The CesA promoter set of the invention offers regulatory sequences of varying strengths which also have the potential to direct tissue-specific expression of transgenes in the same ratios and with a similar tempero-spatial profile as in Eucalyptus spp. The promoters as described herein can be used to express transgenes in a very specific ratio that mimics the ratio of the CesA genes and allow modular expression of such transgenes. The invention also relates to expression cassettes, vectors and transgenic plants containing said promoters, and to a method for the production of said transgenic plants and seeds.
