概括

在Physalis pubescens中进行基因编辑旨在改善诸如产量和水果特性之类的特征. 然而,正统的基因功能显著分化,仅基因编辑并不能产生优异的品种.

科学领域:

园艺科学园艺科学
植物遗传学植物遗传学
基因编辑应用程序

背景情况:

青植物 (Physalis pubescens) 是中国的关键作物,其品种,产量和水果特征都受到限制.
现有的品种,如"金1号" (JH1) 需要改进,以实现商业可行性.

研究的目的:

在P. pubescens"JH1"中利用基因编辑来增强园艺特征.
调查P. pubescens.中与番茄化相关的六个正义基因的功能.

主要方法:

基因编辑被应用于六个正系基因:卵子,化合物发光 (S),甘烯β循环酶 (LCY1),CLAVATA3 (CLV3),水果重量2.2 (FW2.2) 和过多的花器官 (ENO).
编辑突变的表型变异与已知的番茄突变表型进行了比较.

主要成果:

卵子,s和clv3中的突变显示与番茄突变的一致性.
与番茄突变种相比,lcy1,eno和fw2.2中的突变表现出不同的表型.
大多数基因编辑突变的表现比原来的"JH1"品种更差.

结论:

正义基因功能可以在密切相关的物种之间显著分离,如Physalis和西红.
对于功能丧失突变的简单基因编辑对于开发精英P. pubescens品种是不够的.
这些发现为未来的基因改进和生殖细胞在Physalis作物中的生殖质的发展提供了洞察力.

关键词:

肉体 (physalis) 是一个物体.索拉尼姆 (Solanum) 是一种有氧化物.果子的果子的果子的果子的果子功能分歧的功能分歧.基因编辑基因编辑一个正统的基因基因.

Plant Breeding and Biotechnology

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.

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

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...
