Wickramanayake Good morning, everyone! Nice to see you again! I am Ainong Shi, as you know, the teacher for this class. I speak “Chinese English” in the class, and apologize for my strong accent. I am the vegetable breeder in the Department of Horticulture. My hobby is “watching Chinese Kung Fu Movies”. Please introduce yourself!

5 III. PCR and Primer Design
Developed in 1983 by Kary Mulli, who won the Noble Prize for the PCR technology. PCR (polymerase chain reaction) is a technology used to amplify a single copy of DNA segment to millions of copies. And then you can see by eyes or machines. The PCR reaction consists of Denaturation, Annealing, and Extension. Fig from https://www.neb.com/)

6 III. PCR and Primer Design
2. PCR Primer Design Dozens of PCR primer design programs and tools are available for free to use from the Internet. We only discuss three tools: BatchPrimer3 Primer-BLAST SSRLocator >FG938745_UCRVU09_UCR 707 TTTTTTTTTTTTTTTTTACCCAGAAACAGCTTAGAGCGTGAAAGCAAACACTAATGAACAAACCTTGAAAAGGCTTTATATATATACACAGTACACTTAGCAAAAGCACGCCCATACCTGCGTTTTTACATATTTACATCTAACCGACCATAACCATAAACACTGGACAAACTAAGACTCAGCTGTTAAACCACACAAAGCTACCACCATTTCAACCGCTTAACTCATGAACTCATACATATATATATATATATATATATATATATATATATATATATACACACACATATATATGCACAAAAAGGTAAACAAAAATGATACAGCATGACCAAAAAAGGCAGAGGAAAGCAAACTATATTTTCATTCTTTTAGTGATCATGGAGAGTCATTTCTCACACATCGAAAGGAGAAGAAGAGCTTGGTCTGTTCTGGCGAGTCTTCTCGAACGCATCCGATGTCGACCTTCTTCGAAACCGGAAGGACTCTCTAGCTCCTGAAAACGGAGACACCGGAGGAGTAGAACCGGCGGGTGAAGCCGGCGCCGATCCACTCTGACTCTGATATCCGGGTGGCTTCACGATCATGATACTACGTGTAACTCTCATCGCGTCTTCCGGCGAATCCTCACCGTATGACTTCA CGCTTCCGCCGTCTGATTCCTTGCCAGAG .fasta format Example 1: One cowpea EST multiple alleles Example 2: cowpea ESTs with SNPs mapped to the cowpea genetic maps Example 3: Tomato Mosaic Virus resistance gene Tm-2 multiple alleles

7 Tomato Mosaic Virus resistance gene tm2,Tm-2, and Tm-2a [fasta]
Primer Design using Primer-BLAST Design PCR primers using Primer3 and search the forward and reverse primers in all available in GenBank. For example: Tomato Mosaic Virus resistance gene tm2,Tm-2, and Tm-2a [fasta] Shi et al Molecular Markers for Tm-2 Alleles of Tomato Mosaic Virus Resistance in Tomato American Journal of Plant Sciences 2: [pdf]

8 Primer Design using BatchPrimer3
BatchPrimer3 is a tool for designing various primers including for SSRs It can be used for SSR discovery as well Tool website: Web tool: Examples cowpea_EST_1_0693.fasta Pick up part of the EST sequences from below file, cowpea_SSR_SNP_geneticMap_marker.fasta

9 Primer Design using SSRLocator
Install SSRLocator in C: as showing C:\SSRLocatorI Copy your data file with fasta format (.fasta) into the SSRLocatorI folder such as “cowpea_EST_1_0693.fasta” Open SSRLocatorI.exe Format file to SSRLocator Standard in the “Create File” button. Save a new file called “cowpea_EST_1_0693format.fasta” And more ……. Linked

10 Molecular Plant Breeding
Fall 2014 HORT6033 Molecular Plant Breeding Lecture 2 (08/27/2014) IV. Project and Homework The research project for the Fall Semester, 2014 will be SSRs and SNPs discovery and validation in chicory or other crops; Genetic diversity in cowpea or other crops; Trait : markers association analysis in cowpea; Association mapping in spinach or other crops; and QTL mapping for downy mildew resistance in spinach or others. Each Student will work one more project. [pdf] You can work your own project!

11 Molecular Plant Breeding
Fall 2014 HORT6033 Molecular Plant Breeding Lecture 2 (08/27/2014) Homework Discuss SSRLocator installation Discuss how to download cowpea ESTs from GenBank Design allele-specific primers for tm-2, Tm-2, and Tm-2a Read the article Shi et al American Journal of Plant Sciences 2: [pdf]
