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!

III. PCR and Primer Design
1. PCR
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.

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
.fasta format

Example 1: One cowpea EST multiple alleles
http://comp.uark.edu/~ashi/MB/example/cowpea_EST_1_0693.fasta
Example 2: cowpea ESTs with SNPs mapped to the cowpea genetic maps
http://comp.uark.edu/~ashi/MB/example/cowpea_SSR_SNP_geneticMap_marker.fasta
Example 3: Tomato Mosaic Virus resistance gene Tm-2 multiple alleles
http://comp.uark.edu/~ashi/MB/example/tomato_Tm2.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

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:
http://batchprimer3.bioinformatics.ucdavis.edu
• Web tool:
http://batchprimer3.bioinformatics.ucdavis.edu/c
gi-bin/batchprimer3/batchprimer3.cgi
• Examples
cowpea_EST_1_0693.fasta
Pick up part of the EST sequences from below file,
cowpea_SSR_SNP_geneticMap_marker.fasta
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” Linked
 Open SSRLocatorI.exe
 Format file to SSRLocator Standard in the “Create
File” button. Save a new file called
“cowpea_EST_1_0693format.fasta”
 And

Lecture 2 (08/27/2014)
IV. Project and Homework
The research project for the Fall Semester, 2014 will be
1.
SSRs and SNPs discovery and validation in chicory or other crops;
2.
Genetic diversity in cowpea or other crops;
3.
Trait : markers association analysis in cowpea;
4.
Association mapping in spinach or other crops; and
5.
QTL mapping for downy mildew resistance in spinach or others.
Each Student will work one more project.
You can work your own project!
