外媒报转基因木瓜“崩溃”,看农官今后咋吹

  吕永岩按语:转基因木瓜以解决木瓜环斑病为名,转入多种抗生素抗性基因,对人体有巨大潜在危害,国外没人食用,只能做生物燃料。如今转基因导致新谱系病毒出现,转基因木瓜抗性崩溃,完全失败。这又一次证明转基因技术只能戕害人类和环境,给转基因利益集团带来巨大商业利益,不能解决任何实际问题。转基因随着时间的推移,只能丧钟不断。试看转基因农官这下还有啥话说?

  中国转基因番木瓜抗病毒性状崩溃

  【译者点评:人类不可能发明一种植物,没有天敌,专供人类。转基因反自然反科学,不符合达尔文的演化理论。】

  基因观察网消息,转基因番木瓜抗环斑病毒,常常被当做基因工程的一项成功范例。但新研究(英文摘要见后)表明,在中国,这种转基因番木瓜的抗性崩溃,原因是出现了新谱系病毒的压力。

  该研究指出,虽然这种番木瓜种植在夏威夷,抗性仍然保持,但并没有拯救夏威夷的木瓜产业。许多国家不愿食用,大约三分之一的木瓜因损毁被遗弃。美国农业部科学家找到了途径,把没人愿意吃的木瓜制作生物燃料。

  另外,开发了一种非转基因的抗病毒番木瓜,进一步表明了转基因并无需求。

  Virus resistance breaks down in Chinese GM papaya

  Published: 07 August 2018

  Ringspot virus-resistant GM papayas are often cited as a genetic engineering success. But a new study (abstract below) reports that in China, the virus resistance in GM papaya has broken down under pressure from a new lineage of the virus.

  The study reports that the GM virus-resistant papaya planted in Hawaii retains its virus resistance. But this has not saved the Hawaiian papaya industry, since many countries don't want GM papaya and up to a third of the crop is thrown away because it's bruised or mis-shapen. As a result, USDA scientists have been looking at ways to make the unwanted GM papayas into biofuel.

  In addition, a non-GM virus-resistant papaya has been developed, suggesting that the GM version is not needed.
