概括
用Bacillus megaterium (BM) 和Trichoderma harzianum (TH) 接种花生可以增加生长中的生物质和 (Cd) 积累. 特里科德玛哈尔齐安 (TH) 特别有望增强植物提取,而不会影响核产量.
科学领域:
- 农业科学 农业科学
- 环境科学 环境科学
- 微生物学 微生物学
背景情况:
- 阿拉奇斯·海波盖亚 (Arachis hypogaea L.) (花生) 具有显著的 (Cd) 吸收能力.
- 研究微生物注射剂,以控制作物中的重金属积累至关重要.
研究的目的:
- 研究Bacillus megaterium (BM) 和Trichoderma harzianum (TH) 对花生中转移和积累的影响.

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...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
