Promoter elements from the wheat Em gene have been characterized. These
elements are inducible by abscisic acid (ABA) and by osmotic stress. In
this study, we demonstrated that the same promoter elements function in a
distantly related plant species, the moss Physcomitrella patens. Transient
and stable expression of the [beta]-glucuronidase reporter gene was used to
determine that the heterologous wheat promoter also responds to osmotic
stress and ABA in moss. Mutational analysis of the promoter indicated that
the mechanism of gene regulation is conserved in both species. Gel
retardation and DNase I footprint analyses were conducted to characterize
further the interaction of moss transcription factors with the Em promoter.
In addition, the synthesis of stress-related polypeptides in moss was
observed. The evolutionary significance of these data and the potential for
studying the entire ABA perception-response pathway in moss are discussed.
