ST-LS1 is a light-inducible, single-copy gene from potato that is expressed only in photosynthetic tissues. Various sequences derived from the 5'-upstream region of this gene were fused to the coding region of the chloramphenicol acetyltransferase (CAT) gene and to the gene 7 termination region of the transfer DNA (T-DNA) from the Agrobacterium Ti plasmid pTiACH5 and transferred to tobacco using Ti-plasmid vectors. After regeneration of whole plants, tissues were assayed for the expression of the CAT gene. Sequences derived from the 5'-upstream region of the ST-LS1 gene comprising positions -334 to +11 were sufficient to confer a leaf/stem-specific as well as a light-inducible expression of the CAT gene. Destruction of chloroplasts by treatment with the herbicide norfluorazon and subsequent exposure to light drastically reduced the expression of the CAT gene indicating that this upstream sequence most likely interacts with a chloroplast-dependent signal. When sequences from position -98 to position +675 were fused to a truncated inactive fragment of the cauliflower mosaic virus 35S promoter in a head-to-head manner, the corresponding chimeric genes were again expressed in photosynthetic tissues only, indicating that these sequences have enhancer-like properties.
