A Method to Reduce off-Targets in CRISPR/Cas9 System in Plants.

One of the strategies to reduce the off-target mutations in CRISPR/Cas9 system is to use the temperature-independent gene transformation method. Mesoporous silica nanoparticles (MSNs)-gene delivery system is temperature-independent; thus, it can transfer the interesting plasmid (pDNA) to the target plant at different temperatures, including 37 °C. Due to the high activity of SpCas9 at 37 °C compared to lower temperatures, on-target mutagenesis increases at 37 °C.

Analyses of Lysin-motif Receptor-like Kinase () Gene Family in Allotetraploid L. and Its Progenitor Species: An In Silico Study.

The LysM receptor-like kinases (LysM-RLKs) play a crucial role in plant symbiosis and response to environmental stresses. , , and are utilized as valuable vegetables. Different biotic and abiotic stressors affect these crops, resulting in yield losses.

Identification, evolution, expression, and docking studies of fatty acid desaturase genes in wheat (Triticum aestivum L.).

Backgrounds: Fatty acid desaturases (FADs) introduce a double bond into the fatty acids acyl chain resulting in unsaturated fatty acids that have essential roles in plant development and response to biotic and abiotic stresses. Wheat germ oil, one of the important by-products of wheat, can be a good alternative for edible oils with clinical advantages due to the high amount of unsaturated fatty acids. Therefore, we performed a genome-wide analysis of the wheat FAD gene family (TaFADs).

In Silico Analyses of Autophagy-Related Genes in Rapeseed ( L.) under Different Abiotic Stresses and in Various Tissues.

The autophagy-related genes (ATGs) play important roles in plant growth and response to environmental stresses. () is among the most important oilseed crops, but are largely unknown in this species. Therefore, a genome-wide analysis of gene family () was performed.

A novel, simple, and stable mesoporous silica nanoparticle-based gene transformation approach in .

In this study, a novel and stable gene transformation system was developed under control of () as an inducible promoter using the Mesoporous Silica Nanoparticles (MSNs). The functionalized MSNs with a proper particle size were synthesized and attached to a recombinant construct (pDNA) containing gene under the control of promoter (pPZP122:::MSN [pDNA: MSN]) following transformation of tomato plants through injection of the pDNA: MSN complex into tomato red fruit at early ripening stage and then, putative transgenic seeds were collected. As an initial selection, gentamicin-resistant seedlings of T (24.

Strategies to Increase On-Target and Reduce Off-Target Effects of the CRISPR/Cas9 System in Plants.

The CRISPR/Cas9 system (clustered regularly interspaced short palindromic repeat-associated protein 9) is a powerful genome-editing tool in animals, plants, and humans. This system has some advantages, such as a high on-target mutation rate (targeting efficiency), less cost, simplicity, and high-efficiency multiplex loci editing, over conventional genome editing tools, including meganucleases, transcription activator-like effector nucleases (TALENs), and zinc finger nucleases (ZFNs). One of the crucial shortcomings of this system is unwanted mutations at off-target sites.

Studying genetic variability of pomegranate (Punica granatum L.) based on chloroplast DNA and barcode genes.

Chloroplast DNA has been used extensively to analyze plant phylogenies at different taxonomic levels because of its size, organization and sequence conservation. In the present research, two chloroplastic regions, petA–psaJ, trnC–trnD and four DNA barcodes (trnH–psbA, ITS, rbcL, matK), were used to introduce suitable regions for the assessment of genetic diversity among P. granatum L.
