“…Beta carotene is very important in food and provides an essential nutrient to animals that consume them. Moreover, Udoh, et al [19] identified functional SNPs found in the exon region of the LYCE gene at the 1295 nucleotide position of the reference gene (cassava43823. valid.ml) nucleotide variation G/T.…”

Single nucleotide polymorphisms (SNPs) describe a change in a single nucleotide within the genome. SNPs are known as the markers of choice due to their desirable properties such as co-dominant in nature, robust, widely distributed throughout the genome, highly multiplexable, easily automated with high throughput techniques, have high reproducibility, and high efficiency for detection of polymorphism. Several studies have been successfully done for the identifications of the functional SNPs in the plant crops. However, the effects of the identified functional SNPs on plant phenotypes are not yet reviewed so far. Functional SNPs located in the coding regions of the gene can change the first or the second nucleotide sequence in the cordon which in turn alters the amino acid, its sequence, and protein structure that change the activities of the enzymes and finally results in the formation of new traits in the plants. The various desirable phenotypic variations produced within individuals of plant species include grain yields, quality traits, fruit size and shape, tolerance, resistance and adaptation to different abiotic and biotic factors, different colors of fruits and plants, flowering and ripening time. These important phenotypic traits could be improved through breeding using MAS. SNPs that are located in the coding sequence or found near to functional gene controlling desirable traits can help molecular breeder select targeted plant at the early growth stage. This makes the crop improvement program very efficient and rapid. Therefore, the application of marker technology particularly SNPs can increase the speed and efficiency of crop improvement. Therefore, the present seminar paper was targeted to review the application of SNPs in crop phenotypic traits.

“…This method of SNP discovery can only be used if there is an existing information concerning the sequence to be amplified. This method was used by Udoh et al [7] to identify SNPs causing non-synonymous changes in amino acid of phytoene synthase gene in cassava linked to expression of yellow color in roots of some cassava varieties. Also, Harjes et al [8] identified SNPs in the regulatory regions of lycopene epsilon cylase genes causing accumulation of carotenoids in maize.…”

Single nucleotide polymorphism (SNP) represent a change in a single nucleotide within the genome. This can alter the phenotype of an individual within the same species if it occurs in a coding region of the gene. The change in nucleotide can produce desirable characteristic in plants and can become an object for selection. New SNPs have been discovered and subsequently converted to molecular markers using various non-gel based and next generation sequencing platforms. Considering that SNP markers are based on target genes, its abundance in the genome, high automation and multiplexability, has made it a marker of choice and an effective tool for screening plant germplasm for desirable traits. This chapter considers SNP as molecular marker, their discovery and different SNP genotyping methods was documented. A few case studies of SNP as allele specific markers and their association with traits of interest was considered. Thus, highlighting their efficacy as useful tool for marker assisted selection and plant germplasms screening.
