Genetically Modified (GM) Plants were first commercialized in 1996 and the number continually increases every year. In 2009, there were 134 hectares of GM plants in 25 countries. Trends in the research and development of GM plants have changed from the first-generation focus on agronomic traits, such as increased pest and disease resistance, to other areas of development, such as biopharming and bio-fuels, which have been gradually released onto the market. This has resulted in the effort to regulate the use of GM plants through guidelines and laws in many countries. To At present, Thailand uses the Plant Quarantine Act BE 2507 (1964; amendment 2010) to prevent the import of GM plants for commercial release since we still donût have specific laws for GMO regulation; however, a draft Biosafety Act has been approved by the cabinet and is now under consideration by the Office of the Council of State of Thailand.
