Polymerase chain reaction (PCR) is a powerful method to produce linear DNA fragments. Here we describe the Tma thermostable DNA ligase-mediated PCR production of circular plasmid (PPCP) and its application in directed evolution via in situ error-prone PCR. In this thermostable DNA ligase-mediated whole-plasmid amplification method, the resultant DNA nick between the 5' end of the PCR primer and...
We have used random oligonucleotide mutagenesis (or saturation mutagenesis) to create a library of point mutations in the alpha 1 protein domain of a Major Histocompatibility Complex (MHC) molecule. This protein domain is critical for T cell and B cell recognition. We altered the MHC class I H-2DP gene sequence such that synthetic mutant alpha 1 exons (270 bp of coding sequence), which contain ...
Mutagenesis is an important tool for breeding and genomic research. In this study, the germinated seeds isolated microspores of a double haploid line ‘FT’ were treated with EMS, respectively, aim comparing effects two approaches on generating mutants in Chinese cabbage. For microspore EMS mutagenesis, 0.12% 20 min, total 1268 plantlets obtained, 15 M1 screened mutation frequency 1.2%. seed 7800...
