The GMO Panel has previously assessed genetically modified (GM) carnation FLO-40685-2 and concluded that there is no scientific reason to consider that the import, distribution and retailing in the EU of carnation FLO-40685-2 cut flowers for ornamental use will cause any adverse effects on human health or the environment. On 7 November 2017, European Commission requested EFSA to analyse new nucleic acid sequencing data and updated bioinformatics data for carnation FLO-40685-2 and to indicate whether the conclusions of the GMO Panel on the previously assessed GM carnation FLO-40685-2 remain valid. The new sequencing data indicated an additional three base pairs compared to the sequencing data originally provided: one base pair addition to the polyA tail of each of the two inserted flavonoid 3',5'-hydroxylase elements and one base pair addition to the sequence of one of the two D8 promoters in locus 1. These sequence differences are located outside the coding sequence for the newly expressed proteins and the base pairs described as differences in the new nucleic acid sequencing data for carnation FLO-40685-2 were reported to have been already present in the original plant material used for the risk assessment. Thus, with the exception of bioinformatics analyses, the studies performed for the risk assessment of GM carnation FLO-40685-2 remain valid. The new sequencing data and the bioinformatics analyses performed on the new sequence did not give rise to safety issues. Therefore, EFSA concludes that the original risk assessment of carnation FLO-40685-2 remains valid.
转基因生物小组先前已对转基因康乃馨FLO - 40685 - 2进行了评估,并得出结论认为,没有科学依据可认定用于观赏的康乃馨FLO - 40685 - 2切花在欧盟的进口、分销和零售会对人类健康或环境造成任何不利影响。2017年11月7日,欧盟委员会要求欧洲食品安全局(EFSA)分析康乃馨FLO - 40685 - 2的新核酸测序数据和更新后的生物信息学数据,并指出转基因生物小组对先前评估的转基因康乃馨FLO - 40685 - 2得出的结论是否仍然有效。新的测序数据表明,与最初提供的测序数据相比,多了三个碱基对:两个插入的类黄酮3',5'-羟化酶元件中的每一个的polyA尾巴上都增加了一个碱基对,以及位点1中两个D8启动子之一的序列增加了一个碱基对。这些序列差异位于新表达蛋白质的编码序列之外,并且据报道,康乃馨FLO - 40685 - 2新核酸测序数据中描述为差异的碱基对在用于风险评估的原始植物材料中就已存在。因此,除生物信息学分析外,对转基因康乃馨FLO - 40685 - 2进行风险评估所开展的研究仍然有效。对新序列进行的新测序数据和生物信息学分析未引发安全问题。因此,欧洲食品安全局得出结论,康乃馨FLO - 40685 - 2的原始风险评估仍然有效。
