张启发、黄大昉、李家洋、林敏一伙转基因推手帮，对转基因作物不可预料所有恶果“无所不知”却欺上瞒下故意掩盖！黄大昉（中国农业科学院生物技术所研究员、“国家农业转基因生物安全委员会”委员）2010年6月25日全国人大常委会《农业转基因技术和安全管理专题》讲座强调：

基因是含有特定遗传信息的DNA（脱氧核糖核酸）序列，是决定生物特性的最小功能单位。转基因育种就是利用现代生物技术手段，从一个生物体中提取结构、功能清楚的基因再转移到另一个生物体，以获得新性状，培育新品种。转基因水稻据此，必须认为张启发、黄大昉、李家洋、林敏一伙转基因推手帮，对转基因作物不可预料所有恶果“无所不知”却欺上瞒下故意掩盖！

科学证据：中国，广东，中山大学化学与化学工程学院坚持科学精神的博士导师带领的团队在国际权威性学术刊物上发表的《采用光谱与色谱分析结合化学计量学方法研究转基因稻米籽粒（Oryzasativa L.）发生的非预期成分改变》揭露：

Jiao Z et al., Unintended compositional changes in transgenic riceseeds ( Oryza sativa L.) studied by spectral and chromatographicysis coupled with chemometrics methods. J Agric Food Chem. 2010Feb 10;58(3):1746-54. doi: 10.1021/jf902676y.

Abstract

摘要

Unintended compositional changes in transgenic rice seeds werestudied by near-infrared reflectance, GC-MS, HPLC, and ICP-AEScoupled with chemometrics strategies. Three kinds of transgenicrice with resistance to fungal diseases or insect pests werecomparatively studied with the nontransgenic counterparts in termsof key nutrients such as protein, amino acids, fatty acids,vitamins, elements, and antinutrient phytic acid recommended by theOrganization for Economic Co-operation and Development (OECD). Thecompositional profiles were discriminated by chemometrics methods,and the discriminatory compounds were protein, three amino acids,two fatty acids, two vitamins, and several elements. Significanceof differences for these compounds was proved by ysis ofvariance, and the variation extent ranged from 20 to 74% for aminoacids, from 19 to 38% for fatty acids, from 25 to 57% for vitamins,from 20 to 50% for elements, and 25% for protein, whereas phyticacid content did not change significantly. The unintendedcompositional alterations as well as unintended change of physicalcharacteristic in transgenic rice compared with nontransgenic ricemight be related to the genetic transformation, the effect of whichneeds to be elucidated by additional studies.

用近红外反射法、气相色谱-质谱法、高效液相色谱法、电感耦合等离子体原子发射光谱法，并以化学计量法研究转基因稻米籽粒发生的非预期成分改变。对可抗霉菌病和抗虫转基因水稻的三种转基因稻米进行了各自与其对应非转基因稻米的重要营养物质成分的对比性研究，研究的重要营养物质成分为经济合作发展组织（OECD）推荐的蛋白质、氨基酸、脂肪酸、维生素、（微量）元素与抗营养植酸。通过化学计量学方法对成分剖面图进行区分，被区分的成分为蛋白质、三种氨基酸、两种脂肪酸、两种维生素及其他数种（微量）元素。通过分析差异分析证明这些成分存在显著区别，变化幅度为：氨基酸20-74%，脂肪酸19-38%，维生素25-57%，（微量）元素20-50%，蛋白质25%；植酸没有显著变化。转基因水稻转基因稻米与对应非转基因稻米比较的非预期成分性改变与非预期的物理特征改变，可能与基因的转入有关，需要通过更多的研究解释这些变化的作用。
