The relative ease, speed, and biological scope of clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated Protein9 (Cas9)-based reagents for genomic manipulations are revolutionizing virtually all areas molecular biosciences, including functional genomics, genetics, applied biomedical research, agricultural biotechnology. In plant systems, however, a number hurdles currently exist that limit this technology from reaching its full potential. For example,...

Targeting specificity has been a barrier to applying genome editing systems in functional genomics, precise medicine and plant breeding. In plants, only limited studies have used whole-genome sequencing (WGS) test off-target effects of Cas9. The cause numerous discovered mutations is still controversial. Furthermore, WGS-based analysis Cpf1 (Cas12a) not reported any higher organism date.

CRISPR-Cas12a (formerly Cpf1) is an RNA-guided endonuclease with distinct features that have expanded genome editing capabilities. Cas12a-mediated temperature sensitive in plants, but a lack of comprehensive understanding on Cas12a sensitivity plant cells has hampered effective application nucleases editing. We compared AsCas12a, FnCas12a, and LbCas12a for their efficiencies non-homologous end joining (NHEJ) repair profiles at four different temperatures rice. found AsCas12a more to it...

MicroRNAs (miRNAs) are small non-coding RNAs that play important roles in plant development and stress responses. Loss-of-function analysis of miRNA genes has been traditionally challenging due to lack appropriate knockout tools. In this study, single (OsMIR408 OsMIR528) gene families (miR815a/b/c miR820a/b/c) rice were targeted by CRISPR-Cas9. We showed strand conformation polymorphism (SSCP) is a more reliable method than restriction fragment length (RFLP) for identifying CRISPR-Cas9...

Abstract CRISPR-Cas12a is a promising genome editing system for targeting AT-rich genomic regions. Comprehensive engineering requires simultaneous of multiple genes at defined locations. Here, to expand the scope Cas12a, we screen nine Cas12a orthologs that have not been demonstrated in plants, and identify six, ErCas12a, Lb5Cas12a, BsCas12a, Mb2Cas12a, TsCas12a MbCas12a, possess high activity rice. Among them, Mb2Cas12a stands out with efficiency tolerance low temperature. An engineered...

Summary CRISPR ‐Cas9 and Cas12a are two powerful genome editing systems. Expression of in plants is typically achieved with a mixed dual promoter system, which Cas protein expressed by Pol II guide RNA species‐specific III such as U6 or U3. To achieve coordinated expression compact vector packaging, it desirable to express both components under single promoter. Previously, we demonstrated first‐generation transcript unit ( STU )‐Cas9 ‐Cas9‐ RZ , based on hammerhead ribozyme for processing s...

Salinity is a major abiotic stress factor that seriously affects plant growth. Many genes are involved in the response to salt with various metabolism pathways. A number of transcription family have been found be response, and NAM, ATAF CUC (NAC) factors thought act as active regulators during stress, especially stress. In this study, we detected rice NAC coding gene, OsNAC041, confirmed it influenced germination seeds under tolerance plants. OsNAC041 was primarily expressed leaves located...

Rice (Oryza sativa) responds to various abiotic stresses during growth. Plant-specific NAM, ATAF1/2, and CUC2 (NAC) transcription factors (TFs) play an important role in controlling numerous vital growth developmental processes. To date, 170 NAC TFs have been reported rice, but their roles remain largely unknown. Herein, we discovered that the TF OsNAC006 is constitutively expressed regulated by H2O2, cold, heat, abscisic acid (ABA), indole-3-acetic (IAA), gibberellin (GA), NaCl,...

Summary Cytosine base editors (CBEs) are great additions to the expanding genome editing toolbox. To improve C‐to‐T in plants, we first compared seven cytidine deaminases BE3‐like configuration rice. We found A3A/Y130F‐CBE_V01 resulted highest efficiency both rice and Arabidopsis . Furthermore, demonstrated this A3A/Y130F deaminase could be used iSpyMacCas9‐mediated at A‐rich PAMs. showcase its applications, applied for multiplexed generate microRNA‐resistant mRNA transcripts as well...

Summary PAM‐relaxed Cas9 nucleases, cytosine base editors and adenine are promising tools for precise genome editing in plants. However, their genome‐wide off‐target effects largely unexplored. Here, we conduct whole‐genome sequencing (WGS) analyses of transgenic plants edited by xCas9, Cas9‐NGv1, Cas9‐NG, SpRY, nCas9‐NG‐PmCDA1, nSpRY‐PmCDA1 nSpRY‐ABE8e rice. Our results reveal that nuclease editors, when coupled with the same guide RNA (gRNA), prefer distinct gRNA‐dependent sites. De novo...
