Precision genome editing is highly desired for crop *** recently emerged CRISPR/Cas technology offers great potential applications in precision plant genome engineering.A prime editing(PE)approach combining a reverse transcriptase(RT)with a Cas9 nickase and a“priming”extended guide RNA(gRNA)has shown a high frequency for precise genome modification in mammalian cells and several plant ***,the applications of the PE approach in dicot plants are still limited and *** designed and tested prime editors for precision editing of a synthetic sequence in a transient assay and for desirable alleles of 10 loci in tomato by stable *** data obtained by targeted deep sequencing also revealed only low PE efficiencies in both the tobacco and tomato *** assessment of the activities of the PE components uncovered that the fusion of RT to Cas9 and the structure of PE gRNAs(pegRNAs)negatively affected the cleaving activity of the Cas9 *** self-complementarity between the primer binding sequences(PBSs)and spacer sequence might pose risks to the activity of the Cas9 ***,modifying the pegRNA sequences by shortening or introducing mismatches to the PBSs to reduce their melting temperatures did not enhance the PE efficiency at the MADS-box protein(SlMBP21),alcobaca(SlALC),and acetolactate synthase 1(SlALS1)*** data show challenges of the PE approach in tomato,indicating that a further improvement of the PE system for successful applications is demanded,such as the use of improved expression systems for enriching active PE complexes.

this paper presents a new classification for 3-DOF planar parallel manipulators （PPM） with symmetrical configurations and workspace, and the resulted general forms of kinematic model. Under the proposed scheme, 3-DOF PPMs can be classified into two categories. Following this classification, the forward kinematics of Category 1 and Category 2 are derived and presented in this study, which are featured with a sixth order polynomial and a second order polynomial, respectively. the presented forward kinematic models are ready to be computerized and implemented unlike the classifications and models derived by other researchers requiring much more derivation before th.y could be implemented.
