Under the Japanese biosafety regulatory framework for transgenic plants, data for assessing a transgenic plant's impact on biodiversity must be submitted in order to obtain approval for a confined field trial. We recently reported the development of four novel transgenic clones expressing the bacterial () gene, i.e., codAH-1, codAH-2, codAN-1, and codAN-2, and evaluated their abiotic tolerance by semiconfined screen house trial cultivation. Here we evaluated the impacts of the transgenic clones on productivities of harmful substances from those clones to affect soil microorganisms and/or other plants in the environment. A comparison of the assessment data between the transgenic trees and non-transgenic comparators showed no significant difference in potential impacts on biodiversity. The results contribute to sound-science evidence ensuring substantial equivalence between transgenic and non-transgenic .
在日本转基因植物生物安全监管框架下，为获得田间封闭试验的批准，必须提交用于评估转基因植物对生物多样性影响的数据。我们最近报道了四个表达细菌（）基因的新型转基因克隆的开发，即codAH - 1、codAH - 2、codAN - 1和codAN - 2，并通过半封闭温室试验栽培评估了它们的非生物耐受性。在这里，我们评估了转基因克隆对这些克隆产生的有害物质生产力的影响，这些物质会影响环境中的土壤微生物和/或其他植物。转基因树木与非转基因对照之间的评估数据比较表明，对生物多样性的潜在影响没有显著差异。这些结果为确保转基因和非转基因之间实质等同性的可靠科学证据做出了贡献。
