Plant Breeding and Biotechnology

18.9K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

The Central Dogma

21.0K
The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Transgenic Plants

7.2K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

    科学领域:

    • 食品安全和生物技术
    • 微生物学和基因工程学
    • 食品和料中的风险评估

    背景情况:

    • 欧洲食品安全局评估了用于食品,料和环境释放的微生物的新基因组技术 (NGT).
    • 视野扫描确定了NGT修饰的微生物 (NGT-Ms),预计在10年内出现在欧盟市场.
    • 评估涵盖了可活的微生物 (4类) 和不可活的产品 (3类).

    研究的目的:

    • 提供关于NGT应用于食品,料和环境用途的微生物的科学意见.
    • 与已建立的基因组技术 (EGT) 和常规突变发生学相比,评估与NGT-Ms相关的潜在新型危险.
    • 评估现有的EFSA指南对NGT-Ms的适用性.

    主要方法:

    • 地平线扫描以识别NGT-Ms.
    • 对NGT-Ms与EGT和常规突变发生的比较危险评估.
    • 审查现有的EFSA指导文件.

    主要成果:

    • 与EGT或常规突变发生相比,NGT-Ms没有发现新的潜在危险.
    • NGT的效率,特异性和可预测性可能会导致基因组改变相关的危险减少.
    • 现有的EFSA指南部分适用,其中一些需要对NGT-Ms进行更新.

    结论:

    • 需要更新EFSA指南,因为有些指南对NGT-Ms.不够.
    • 风险评估应在通过常规突变发生,EGT或NGT修饰的微生物中保持一致.
    • 一个个案例的方法可能允许减少对特定NGT-Ms的要求.
