Title	The promoter of the gene ltr1 from barley confers a different tissue specificity in transgenic tobacco
Journal	Molecular and General Genetics
Year	1995
Volume	248
Pages	592-598
Author	Diaz I Royo J O'Connor A Carbonero P
Abstract	Tissue-specific expression of the gene coding for trypsin inhibitor BTI-CMe in barley (Itr1) occur during the first half of endosperm development In transgenic tobacco, the Itr1 promoter drives expression of the beta-glucuronidase reporter gene not only in developing endosperm but also in embryo, cotyledons and the meristematic intercotyledonary zone of germinating seedlings A promoter fragment extending 343 bp upstream of the translation initiation ATG codon was sufficient for full transgene expression, whereas, the proximal 83 bp segment of the promoter was inactive Possible reasons for the differences in expression patterns are discussed
