Gene editing in agriculture is good?5 answersGene editing in agriculture presents both opportunities and challenges. Proponents highlight its potential to enhance productivity, sustainability, and climate adaptation. However, concerns exist regarding regulatory frameworks, social acceptance, and the need for responsible innovation. Public opinion varies, with some expressing opposition due to fears of perpetuating industrialized agriculture, while others support gene editing for its potential benefits in addressing urgent issues like climate change. Social media plays a significant role in shaping discussions around gene editing in agriculture, with positive sentiments leading to increased engagement. Overall, gene editing holds promise for improving crop traits, disease resistance in livestock, and food distribution efficiency, but careful consideration of societal priorities and regulatory aspects is crucial for its safe and responsible implementation.
How biotechnology genetic engineering can help agriculture?5 answersBiotechnology and genetic engineering can help agriculture in several ways. They allow for the transfer of targeted genes from one plant to another, resulting in genetically modified organisms (GMOs). This process differs from traditional breeding and boosts crop yield effectiveness, leading to increased crop yields and lower costs for food or drug production. Genetic engineering also improves nutrient composition, food quality, and pest and disease resistance in crops. Additionally, it can enhance food security and provide medical benefits. Genetically modified crops have the potential to address hunger and malnutrition issues, contribute to environmental conservation, and increase productivity in sustainable agricultural practices. The use of molecular tools, such as the CRISPR/Cas9 platform, allows for genome editing without transgenic modifications, facilitating the development and commercialization of GM crops. Overall, biotechnology and genetic engineering offer innovative solutions to improve crop production and sustainability in agriculture.
Which cloning methods are used in crispr/cas mediated plant genome editing?5 answersCRISPR/Cas mediated plant genome editing utilizes various cloning methods. One commonly used method is the modular cloning (MoClo) based on the Golden Gate (GG) method, which allows for quick and easy assembly of genetic parts into expression units. This method has been used to develop a cloning toolkit containing modules encoding CRISPR/Cas-based nucleases and their corresponding guide RNA backbones. Another method involves the delivery of CRISPR/Cas as ribonucleoprotein, which does not require the insertion of foreign DNA and allows for precise genome editing without genome shuffle. Additionally, the tRNA-sgRNA system has been used for facile assembly of polycistronic units without the need for a PCR step. These cloning methods have been applied in plant species such as rice, wheat, maize, tomato, soybean, and Nicotiana benthamiana.
What is genetic editing techniques use in GM soy?4 answersGenetic editing techniques used in GM soy include genome editing to modify the transcription regulatory region or sequence encoding HECT E3 ligase polypeptides. Another technique involves using a hairpin RNA-encoding construct to target specific genes, such as gmFAD2-1, and employing an Agrobacterium-mediated embryonic tip system for transformation. Additionally, the technique of germ-line genetic transformation via natural pollen tubes as vectors has been used to introduce key lignification genes into the soybean genome. These techniques have been successful in modifying the expression or activity of specific genes in soybean plants, resulting in altered composition such as increased protein, decreased soluble carbohydrate, increased oleic acid, and decreased saturated fats. They have also been used to enhance the innate defense of soybean plants against pests and pathogens by improving the content and composition of lignin.
How do Agrobacterium rhizogenes and Agrobacterium tumefaciens differ in their ability to transform plants?5 answersAgrobacterium rhizogenes and Agrobacterium tumefaciens differ in their ability to transform plants. A. rhizogenes induces root proliferation in dicotyledonous plant species, resulting in "hairy roots" formation. On the other hand, A. tumefaciens transfers its own T-DNA into the plant's genome, leading to the generation of transgenic plants. A. rhizogenes transformation involves infecting stems with the bacteria, resulting in the emergence of transformed hairy roots. In contrast, A. tumefaciens transformation is achieved by infecting leaves, selecting transformed cells, and regenerating complete transformed plants. A. rhizogenes transformation is a faster alternative for studying gene expression in roots, as it allows for the detection of GUS activity in the emergence of lateral roots. Overall, A. rhizogenes and A. tumefaciens have distinct mechanisms and applications in plant transformation.
What are gene edited crops?3 answersGene edited crops are crops that have been modified using gene editing technology to introduce specific genetic changes. This technology allows for precise manipulation of the crop's genome, targeting desired traits such as improved yield, nutritional quality, and tolerance to abiotic and biotic factors. Gene editing techniques, such as CRISPR/Cas, have been used to edit genes responsible for economically valuable traits in crops, including ornamental plants. The research on gene editing in crops has focused on improving traits related to quality, such as starch, lipids, proteins, and other functional components. Gene editing can be used to create new varieties and crops with targeted genetic changes, benefiting consumers, the environment, and farmers. The regulatory approval of gene-edited crops varies by country, with some treating them as conventional crops and exempting them from restrictive policies applied to genetically modified organisms (GMOs). Overall, gene edited crops have the potential to contribute to sustainable agriculture, food security, and the improvement of specialty crops.
