Abstract
Regulatory regions from maize .alpha.-tubulin genes are disclosed. In particular, 5' regulatory regions comprising an upstream regulatory ensemble (URE) from maize .alpha.-tubulin 1 and 3 genes is useful in tissue specific expression of heterologous genes in transformed plants. The maize .alpha.-tubulin URE comprises regulatory elements which when operably linked to a promoter and heterologous gene, confer regulated expression in roots, pollen and meristematic tissues. Expression constructs which confer tissue specific expression are also provided.
