Summary of the CRISPR/Cas9 based steps of plant genome editing. In the first step identification of best target sites is done using various online tools and primers are designed. The target-specific sgRNA with Cas9 cassettes are cloned in binary vector. In next step cassettes are then co-transformed in vivo into the plants. The transgenic plants are confirmed for the target-specific mutations using various approaches like high-throughput sequencing approaches. The positive transformed plant is then selected for further applications and analysis.

Gene-based markers are helpful in unraveling the marker-trait association and landing onto a candidate gene than genome wide spanned SSR markers. The DMBSSR 125 marker loci can be used in development of bruchid tolerant varieties with prior validation. Further, the two candidate genes vigra. Vradi09g07610 and Vradi0111s00070 can be targeted to reveal the useful variations.

💡 Key Considerations for Designing a #Genetic Panel When designing a genetic #panel, several critical factors must be considered, including the selection of the gene list, appropriate CPT codes, #GeneticCounseling service and the reimbursement rate... As a consulting service, we meticulously analyze each panel and collaborate closely with the laboratory to ensure the development of the most clinically relevant panels while also optimizing reimbursement rates. Our primary goal in building any clinical test is to put patients first. Contact us today to develop your future in-house genetic panels! info@avicennalabconsulting.com #CLIA #CAP #COLA #Clinicallaboratory #Moleculardiagnostic #genepanel #genetics

You have a strain culture and want to know its gene pool? We use whole genome sequencing to map the full genome of organisms in culture and can help you understand the specific genes encoded by your organism. Such information can help you understand its functions and possible value. Does it possess key nitrogen fixation genes, phosphorus solubilization genes, antibiotic resistance? The analyses can also help understand the specific strain you have grown if you are unsure. Send us an email or give us a call to discuss the options.

Mitigation of TDP-43 toxic phenotype in amyotrophic lateral sclerosis models Under pathological conditions, TDP-43 aggregates sequester RNAs, other RNA-binding proteins or other proteins that can interact with TDP-43, leading to a toxic gain-of-function. When n N-terminal fragment of a protein called RGNEF (NF242) is expressed genetically or using adeno-associated viruses, it binds to TDP-43 aggregates and blocks sequestration of RNAs and proteins, thus inhibiting the toxic gain-of-function. #sciencenewshighlights #ScienceMission https://lnkd.in/d_U5hXDk https://lnkd.in/dWhhYNAH

Identification of biallelic POLA2 variants in two families with an autosomal recessive telomere biology disorder #RareDisease #Genetics They identified biallelic deleterious variants in the accessory subunit of DNA polymerase alpha 2 (POLA2) gene in five individuals from two unrelated families. All five individuals displayed abnormally short telomeres and a clinical phenotype suggesting a telomere biology disorder (TBD) with Coats plus features including retinal and gastrointestinal telangiectasias. https://lnkd.in/di5y9WqV

🥼 In a study by Toussaint et al., the Hidex Sense multimode compact plate reader has been used to identify the physiological conditions that activate competence for DNA transformation in Lactococcus lactis, the most important lactococcal species. 🦠 The Sense was used to monitor the expression of the master regulator ComX gene through luminescence. Growth (OD600) and luciferase activity were monitored at 5-minute intervals on the reader for a maximum of 24 hours. 👉 You can learn more about the study by Toussaint et al by clicking here: https://lnkd.in/emxAT49s

Inbreeding and Loss of heterozygosity explained Loss of heterozygosity (LOH) is a type of genetic abnormality in diploid organisms in which one copy of an entire gene and its surrounding chromosomal region are lost.[1] Since diploid cells have two copies of their genes, one from each parent, a single copy of the lost gene still remains. But any heterozygosity, slight differences between the versions of the gene inherited from each parent, is no longer present. Youtube video: https://lnkd.in/dDnX2RtU #nikolaysgeneticslessons

What are Additive genetic effects? Additive genetic effects occur when two or more genes source a single contribution to the final phenotype, or when alleles of a single gene (in heterozygotes) combine so that their combined effects equal the sum of their individual effects. Non-additive genetic effects involve dominance (of alleles at a single locus) or epistasis (of alleles at different loci). Youtube video: https://lnkd.in/drKhVpic #nikolaysgeneticslessons
