Lycopersicon esculentum Miller Transformation

Lycopersicon esculentum Miller Transformation Inquiry

Lycopersicon esculentum Miller, also known as tomato, belongs to the tomato family Solanaceae, and is an annual or perennial herbaceous plant. Lycopersicon esculentum Miller is rich in nutrients and has unique flavor, like carotene, lycopene and other nutrients, which are strong antioxidants that can effectively remove free radicals in the body, prevent and repair cell damage, and inhibit the spread and replication of cancer cells. Favored by consumers, it is now widely grown as an important edible fruit and vegetable in the world. In recent years, research on genetically modified Lycopersicon esculentum Miller has become a hot field to improve Lycopersicon esculentum Miller disease resistance, insect resistance, herbicide resistance, salt tolerance, cold tolerance, storage tolerance, fruit flavor, lycopene yield, etc.

Lycopersicon esculentum Miller transformation

Lifeasible provides one-stop services, covering all steps including experimental design, vector construction, plasmid transformation, positive transplant screening and characterization of transgenic Lycopersicon esculentum Miller. We offer Lycopersicon esculentum Miller transformation using various genetic engineering technologies as follows:

Through the quantitative overexpression of genes related to lycopene, anthocyanin, malic acid and other chemical components in Lycopersicon esculentum Miller, the production of specific compounds can be increased. We could help you overexpress many enzymes of the Rohmer pathway which might be critical for lycopene biosynthesis, SlMYB12 gene that has an important effect on the color of Lycopersicon esculentum Miller, and many other genes related to important traits of Lycopersicon esculentum Miller.

RNAi technology is widely used in the field of gene editing, it refers to the phenomenon of highly conserved, induced by double-stranded RNA (dsRNA), homologous mRNA high-efficiency and specific degradation in the evolutionary process. Through RNAi technology, the silencing of multiple genes in Lycopersicon esculentum Miller can be mediated.

Virus induced gene silencing (VIGS) means that after viruses carrying target gene fragments infect plants, they can induce plant endogenous gene silencing and cause phenotypic changes, and then study the function of target genes based on phenotypic variation. The VIGS technology is a method of transient transformation and underlying molecular basis may be post-transcriptional gene silencing. Silencing and functional analysis of target genes in Lycopersicon esculentum Miller through VIGS can help you save time and achieve valuable information for gene functional analysis. With wealth of experience in VIGS, the scientists in Lifeasible provides you customized protocol for VIGS in Lycopersicon esculentum Miller. We could achieve the transformation for Lycopersicon esculentum Miller with different genetic backgrounds.

The discovery of the CRISPR/Cas9 system provides us with a very powerful and convenient gene editing tool. By using CRISPR technology, we can knockout Lycopersicon esculentum Miller genes in different ways, including frameshift mutations, multiple deletion of fragments, knockout of non-coding genes, knockout of multiple copies of genes, etc.

CRISPR system has strong scalability, and this scalability can be used to develop more useful gene editing tools. we have developed many methods that can improve gene knock-in efficiency and achieve precise editing of the Lycopersicon esculentum Miller genome. For the gene knock-in process, most of CRISPR gene knock-in is done through HDR. However, NHEJ and HDR will occur at the same time due to DNA breaks. Therefore, we have developed different methods to increase the probability of HDR, thereby improving the efficiency of gene knock-in.

CRISPR Single base editing technology is a hot area of life science research today. As a company that has been cultivating gene editing technology for decades, Lifeasible cougld help you achieve the conversion from C to T or A to G in Lycopersicon esculentum Miller using CBE and ABE, both of which rely on the DNA positioning capabilities of the CRISPR/Cas9 system. During single base editing, the C base deaminase or A base deaminase is located at a specific position in the genome, and it catalyzes the deamination reaction of C or A at a specific position and turns it into U or I. Then it is treated as T or G in the process of DNA replication, realizing the conversion from C to T or A to G.

As a variant of CAS protein after domain inactivation, dCAS9 still retains the ability to recognize and bind to specific DNA sequences, so it can derive many important functions. One of them is CRISPR Interference. There are many ways to participate in the inhibition of gene expression. For the inhibition of Lycopersicon esculentum Miller genes, we can provide a variety of solutions, including dCas9 binding to targeted DNA and realizing Inhibition of gene transcription through steric hindrance. In addition, gene knockdown can also be achieved by recruiting a fusion protein to the start site of gene transcription.

CRISPRa technology uses the powerful capabilities of Cas9 and sgRNA to fuse or recruit multiple proteins to enhance gene transcription. For Lycopersicon esculentum Miller genes, we provide VPR technology, SAM technology and Suntag technology to allow the CRISPR system to carry more activation element and achieve a stronger activation effect after synergistic amplification.

The study of gene function has always been the core subject of biological research. The earliest genetic screening system established through forward genetics is very inefficient and has a huge workload. However, the reverse genetic screening system based on CRISPR technology can complete very low-cost mutation library construction work. The gene mutation library construction technology we provide for Lycopersicon esculentum Miller including gene knockout library construction, gene knockdown library construction, and gene activation library construction. Moreover, single-cell sequencing is available for mutation screening.

DNA-free gene editing technology has received extensive attention from the industry in recent years. We provide DNA free Lycopersicon esculentum Miller genome editing services, including transient expression of CRISPR/Cas9 plasmid DNA, in vitro transcription of CRISPR/Cas9, and pre-assembled ribonucleic acid composed of purified Cas9 protein and sgRNAs complex. These technologies can avoid the integration of foreign DNA and genome, and reduce off-target effects. In addition, compared with traditional techniques, these techniques can avoid the use of hybridization or backcrossing to isolate CRISPR/Cas9 chimeras, so they are cheaper and have shorter experimental cycles.

Genetic Transformation Process for Lycopersicon esculentum Miller

So far, the most advanced and widely used method for the development of genetically modified Lycopersicon esculentum Miller is Agrobacterium-mediated transformation. Briefly, the foreign target gene is transferred and integrated into plant cells through Agrobacterium, and then transformed plants are regenerated through techniques such as tissue culture.
