概括

表达mCherry的转基因番茄植物表达了组织特异性表达,但没有足够的灵敏度来检测白或它们的蛋中的记者. 对于有效的害虫控制策略,需要进一步的研究.

科学领域:

植物生物技术植物生物技术
昆虫学昆虫学是一门学科.
分子生物学分子生物学

背景情况:

开发转基因植物以准像白 (Bemisia tabaci) 这样的害虫是一种潜在的杀虫剂策略.
这项研究评估了使用mCherry记者基因在转基因番茄植物中的两种蛋白质输送方法.

研究的目的:

用转基因番茄植物向白蛋提供杀虫剂蛋白质的两种策略的有效性进行评估.
评估mCherry记者基因在检测白及其卵中的蛋白质积累时的灵敏度.

主要方法:

通过使用数字PCR生成同卵性转基因番茄线.
采用了两种策略:一种是用糖转移酶分泌信号,另一种是以蛋白质转导域 (PTD) 和维特洛根因序列在体内准白蛋.
利用一个康梅琳娜病毒促进剂用于体特异性表达.

主要成果:

第一个策略显示mCherry的细胞积累,但没有证据在蛋中.
针对白蛋的第二个策略没有达到足够的mCherry积累,以检测成年白或它们的蛋.
消化卵中的蛋白酶活性可能会干扰蛋白质检测.

结论:

mCherry 是一个适合于番茄植物组织特异表达的记者.
报告系统的灵敏度不足以检测或蛋中的蛋白质.
同胞性转基因系对于准确的结论至关重要关于害虫控制策略.

Transgenic Plants

Transgenic Plants

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...

Plant Breeding and Biotechnology

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.
