Description Gene families, like the conserved transcription factor families, evolve through gene duplications and share moderate similarity
between member genes. Lack of genomic data makes it difficult to design high-specificity primers to the target genes.
Furthermore, many primers under-perform in highly sensitive assays like quantitative PCR due to issues of thermodynamic
nature, thereby increasing the cost and time for analysis. A methodology involving intra-species and inter-generic bioinformatic
sequence comparison combined with thermodynamic estimation of primer performance was used for one-time design of
gene specific primers for different WRKYs, Mitogen Activated Protein-kinases and N-methyltransferases of Coffea canephora
without the aid of genome sequence resources. Out of a total 37 primer sets including 31 pairs of primers for WRKY from
34 mined WRKY Unigenes/ESTs and six pairs for genes coding for MAP kinases and NBS-LRR proteins, 32 sets exhibited
high specificity of amplification upon genome analysis as well as in the high-resolution melt analysis. Furthermore, PCR
optimization strategies-both in silico and experimental-indicated a superior performance of the primer sets for different
applications like quantitative PCR and rapid amplification of cDNA ends. Only one set of primer resulted in mis-priming
upon confirmation by DNA sequencing of the cloned amplicons. The intra-species differences and inter-generic similarities
ensure high specificity of primers in all cases studied. The procedure allowed design of primers for the use in different
downstream applications with high performance, specificity, yield and ease-of-use.
