In vitro transcription systems provide a powerful tool for detailed an
alysis of transcription reactions including initiation, elongation, an
d termination. Despite problems inherent to plant cells, efforts have
been made to develop plant in vitro transcription systems in the past
decade. These efforts have finally culminated in the development of re
liable in vitro systems from suspension-cell cultures of both monocot
and dicot plants. These systems can be useful in elucidating the speci
fic mechanisms involved in the process of plant transcription and thus
can potentially open a new era of transcription studies in plants.
