摘要：

A cell suspension culture of Phaseolus vulgaris cv Negro jamapa was established. Protoplasts isolated from this culture are suitable for transient gene expression studies after DNA transfer by either electroporation of treatment with polyethylene glycol. The optimized conditions for both methods were established, taking into consideration expression and cell viability. We have investigated two features of posttranscriptional gene regulation. We demonstrate that inclusion of the RNA leader sequence, omega (OMEGA), derived from tobacco mosaic virus, and a dicot intron in the leader region together enhance gene expression in this legume species about 10-fold.
