Methanol production is enhanced by expression of an Aspergillus niger pectin methylesterase in tobacco cells

Tobacco suspension culture cell (Nicotiana tabacum, BY2) was transformed with an Aspergillus niger pectin methylesterase (PME; EC 3.1.1.11) cDNA under the control of cauliflower mosaic virus (CaMV) 35S promoter. The transformant indicated a significant rise of PME and the level of methanol in the transformant increased by 28.7% compared to the vector control transformant. This is the first report of methanol overproduction in plant cells by means of genetic engineering. (C) 2003 Elsevier B.V. All rights reserved.
