HHS University of Göttingen. COVID-19 is an emerging, rapidly evolving situation. Rogowsky, P.M. CRISPR-Cas Technology in Plant Science. Predictions suggest that small farms in Africa and Asia will suffer especially from the effects of climate change. Genome editing techniques in particular, such as CRISPR/Cas, could help to make agriculture more productive and environmentally friendly. The CRISPR/Cas9 technology is therefore more versatile for genome editing in plants generally but particularly suitable for monocots with high genomic GC content such as rice (Miao et al., 2013). In addition, computational algorithms such as Cas-OFFinder (Bae et al., 2014), CRISPR-P (Lei et al., 2014), CRISPR-Plant (Xie et al., 2014), and CRISPR Primer Designer (Yan et al., 2015b) have been created to aid the rational design of gene-specific sgRNAs with minimal off-target probabilities based on the deciphered genome sequence. Recent advances in CRISPR/Cas genome editing enable efficient targeted modification in most crops, thus promising to accelerate crop improvement. 60, 353–360 (2017). Prior 'Common Colds': Less Severe COVID-19? Presently, the generation of random mutations at a predetermined site of the genome is well mastered, just like the targeted insertion of transgenes, although both remain restricted to species or genotypes amenable for plant transformation. CRISPR is an acronym for clustered regularly interspaced short palindromic repeats and Cas9 is a nuclease associated with CRISPRs.These 29-nucleotide (nt) repeat sequences separated by various 32-nt spacer sequences were first reported in bacteria as early as 1987 .Later, they were found in 40% of sequenced bacterial genomes and 90% of archaea . The off-site targeting is minimised to a greater extent with the advent of various in silico tools which provide a means of selecting the guide RNA of choice.

Future technologies need to reduce the negative environmental footprint and make agriculture more resilient to climate stress. PLoS One 10:e0144591, Article  Trends Plant Sci 20:426–434, Article  Finally, we discuss prospective applications of this game-changing technology. "Plant breeding and other agricultural technologies have contributed considerably to hunger reduction during the last few decades," says Matin Qaim, an agricultural economist at the University of Göttingen and one of the article's authors. Fine tuning and knock out of master switches in wild crops to increase genomic diversity and accelerate the domestication process. In genome editing, certain DNA sequences are changed or "switched off" in a very precise way without foreign genes being introduced. Plant Cell Rep 34:1473–1476, Wang X, Tu M, Wang D, Liu J, Li Y, Li Z, Wang Y, Wang X (2017) CRISPR/Cas9-mediated efficient targeted mutagenesis in grape in the first generation. ScienceDaily shares links with sites in the. The bottleneck in the application of CRISPR/Cas9 technology to a wide range of crops is clearly the regeneration of fertile plants from the cells into which the CRISPR/Cas9 tool has been introduced (Altpeter et al., 2016). Additionally, other applications of CRISPR/Cas in plant virology such as virus diagnostics and imaging are reviewed. 2019 Oct-Dec;11(4):13-21. doi: 10.32607/20758251-2019-11-4-13-21. Additionally, other applications of CRISPR/Cas in plant virology such as virus diagnostics and imaging are reviewed.

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated genes (Cas) is a prokaryotic adaptive immune system which has been reprogrammed into a precise, simple, and efficient gene targeting technology. The clustered regularly interspaced short palindromic repeats/CRISPR-associated (CRISPR-Cas) system is an immunity mechanism against the foreign genetic elements such as virus and plasmids present in bacteria and archaea.

RNA-guided Cas enzymes have been adopted as tools to manipulate the genomes of cultured cells, animals, and plants, accelerating the pace of fundamental research and enabling clinical and agricultural breakthroughs. Additionally, a Ppr-clv1 null allele took a huge effect on fruit size, with a 24% increase in fruit mass, accentuating that semi-domesticated and wild crops can be domesticated with CRISPR/Cas technology.
