摘要

The gene of the first key enzyme of poly-β-hydroxybutyrate synthesis, 3-ketothio- lase, has been amplified and cloned from chromosomal DNA of Alcaligenes eutrophus H16 by PCR. DNA sequencing results show that phbA cloned in pBluescriptSK~+ has an identical se- Quence with that reported previously except for one baser pair. The plant constitutive expression Vector has been constructed and tobacco has been transformed in order to examine the phbA Gene function and the efficiency of ctp gene product.
