The tubB1 beta-tubulin gene of Glycine max (previously named s beta 1) is highly expressed only in rapidly elongating regions of etiolated seedling hypocotyls and this expression is strongly downregulated when the seedlings are exposed to light. Primer extension demonstrated that the gene was transcribed in these tissues and contained two sites of transcriptional initiation. To determine the mechanism regulating tubB1 expression, a chimeric reporter gene was constructed by fusing 5' upstream… CONTINUE READING
