Abstract

A selectable marker, the ASA2 gene of Nicotiana tabacum, is provided for transforming plant cells. The ASA2 promoter sequence is also provided which is capable of directing tissue culture specific transcription of a downstream structural gene. Also disclosed are truncated forms of the ASA2 promoter which are capable of directing high level constitutive transcription of downstream structural genes. Constructs containing the above genes and promoters are also disclosed.
