Heterologous expression of recombinant alcohol dehydrogenase gene from sago palm in bacterial and plant system

Alcohol dehydrogenase (ADH) is an enzyme involved in pathways that respond to various environmental stresses such as osmotic, wound and anaerobic condition. In this study, the recombinant Metroxylon sagu Adh1 cDNA (r-msAdh1) was cloned into an expression vector; pET-41a(+) and expressed in Escherich...
