CRISPRCas9 is a simple twocomponent system that allows researchers to precisely edit any sequence in the genome of an organism This is achieved by guide RNA, which recognizes the target sequence, and the CRISPRassociated endonuclease (Cas) that cuts the targeted sequence Researchers across the globe who are adopting this technology are bound to come across an important term PAM sequence This system consists of the Cas9 endonuclease in complex with a small guide RNA (gRNA) that is engineered to target a specific site in the genome The target site is defined by a nucleotide guide sequence at the 5′ end of the gRNA, making programming of Cas9 nucleases can be programmed with single guide RNAs (sgRNAs) to mediate gene editing High CRISPR/Cas9mediated gene knockout efficiencies are essential for genetic screens and critically depend on the properties of the sgRNAs used The specificity of an sgRNA is defined by its targeting sequence Here, we discovered that two short sequence

PAM (seed region) are especially important for target site recognition In many cases, offtarget mutations happen at sites where the gRNA seed region has no mismatches but the nonseed region does 3, 15 To knock out a specific region in the genome, such offtarget effects should be avoided Reducing such risk is espeIf gRNA expression is too high, reduction can be accomplished by inclusion of a UUU stretch in the seed region, which may lead to partial transcriptional termination and lower expression levels (Wu et al 14) Given the higher degree of specificity in plants, it is unlikely that gRNA expression levels are a general concernFigure 2A) The PS1–gRNA seed region (22 nt) was predicted to pair with the template strand of OsMPK5, and would guide Cas9 to make DSB at a KpnI site

Herein, unlike previous engineering of gRNA that generally focused on the RNA part only but neglected RNA–protein interactions, we aimed at the interactive sites between 2′OH of ribose in the seed region of gRNA and the Cas9 protein and identified that chemical modifications at specific sites could be utilized to regulate the Cas9 activity It was suggested that the gRNA sequence of CRISPRCpf1 should be divided into seed (6 nt in the 5' PAMproximal end) and nonseed (14 nt in the 3' PAMdistal end) regions (Kim et al, 17b, 18) The tolerant ability of mismatches in the seed region is lower than that in the nonseed regionCasbased technology is gRNA design The DNA, unwound by Cas9, is probed by the gRNA sequence adjacent to the PAM13,14 The first few nucleotides are referred to as the ''seed'' sequence, where Cas9 is most sensitive to mismatches If there is full seed region complementarity, Cas9 is more likely to remain bound to the

 It is, in fact the, the "central seed" binding region in the gRNA with 8 central bases (11–18 nts) which upon complementing SS region in theThe complex then scans the DNA for a complementary sequence to the nucleotides on its 5′ end, termed the guide region (spacer region), with an adjacent upstream protospacer adjacent motif (PAM) sequence (5′NGG3′ in S pyogenes) ( Jiang and Doudna, 17 ) The PS1–gRNA seed region (22 nt) was predicted to pair with the template strand of OsMPK5, and would guide Cas9 to make DSB at a KpnI site The PS2– and PS3–gRNA seeds region ( and 22 nt, respectively) were predicted to pair with the coding strand of OsMPK5, and PS3–gRNA would guide Cas9 to make DSB at a SacI site Subsequently, three gRNA–Cas9

The seed sequence is essential for the binding of the miRNA to the mRNA The seed sequence or seed region is a conserved heptametrical sequence which is mostly situated at positions 27 from the miRNA 5´end Even though base pairing of miRNA and its target mRNA does not match perfect, the "seed sequence" has to be perfectly complementaryWong et al further analyzed the dataset of Doench et al and reported that nucleotides at position 18– are the seed region of the gRNA This region and the nucleotides located at 51–53 should be unbound and accessible to form efficient gRNAs If the seed region would bind to position 51–53 of the gRNA, it would be nonfunctional The 3′ end of the guide sequence, also known as the "seed region", plays a critical role in recognition of target sequence Thus, based on structural analysis, accessibility of the last three bases in the seed region was a prominent feature to differentiate functional sgRNAs from nonfunctional ones (Fig 1b )

The sequence beyond the seed region also confers target specificity However, two mismatches (eg, in the case of egfp OT1) could be tolerated These results are consistent with a recent study by Fu et alIn addition, we examined UUU in the gRNA seed region, which are the 6 nucleotides in the 5' PAMproximal region 41, and found that more inefficient gRNAs contains UUU in the seed region than efficient ones with an enrichment ratio of 029 (P = 907E02), which is consistent with previous CRISPRCas9 research 48Guide RNA (gRNA) is a piece of RNAs that function as guides for RNA or DNAtargeting enzymes, which they form complexes with Very often these enzymes will delete, insert or otherwise alter the targeted RNA or DNA They occur naturally, serving important functions, but can also be designed to be used for targeted editing, such as with CRISPRCas9 The mismatch intolerant seed region of
