Abstract
Pepper is an economically important horticultural plant that has been widely used for its pungency and spicy taste in worldwide cuisines. Therefore, the domestication of pepper has been carried out since antiquity. Owing to meet the growing demand for pepper with high quality, organoleptic property, nutraceutical contents, and disease tolerance, genomics assisted breeding techniques can be incorporated to develop novel pepper varieties with desired traits. The application of next-generation sequencing (NGS) approaches has reformed the plant breeding technology especially in the area of molecular marker assisted breeding. The availability of genomic information aids in the deeper understanding of several molecular mechanisms behind the vital physiological processes. In addition, the NGS methods facilitate the genome-wide discovery of DNA based markers linked to key genes involved in important biological phenomenon. Among the molecular markers, single nucleotide polymorphism (SNP) indulges various benefits in comparison with other existing DNA based markers. The present review concentrates on the impact of NGS approaches in the discovery of useful SNP markers associated with pungency and disease resistance in pepper. The information provided in the current endeavor can be utilized for the betterment of pepper breeding in future.
Highlights
Pepper is a diploid and self-pollinating plant belonging to the genus Capsicum in the Solanaceae family
The elucidation of gene specific polymorphism and single nucleotide polymorphism (SNP) analysis associated with the capsaicin biosynthesis pathway by Reddy et al [27] aided in the development of markers related to capsaicinoid metabolic pathway in pepper
Anthracnose is a predominant fungal disease caused by Colletotrichum species in pepper plants grown worldwide; the highest rate of infection has been reported in Asia [45]
Summary
Pepper is a diploid and self-pollinating plant belonging to the genus Capsicum in the Solanaceae family. The availability of several computational methods and genotyping approaches to efficiently detect and validate SNPs in the genome aids in the identification of vital SNPs associated with trait of interest. The report suggested the importance of the nextgeneration resequencing approaches in cohort with the SNP markers for the development of novel tools for the pepper breeding. The GBS based discovery of SNP markers in a collection of Capsicum subspecies resulted in the identification of genetic diversity in 222 cultivated pepper genotypes [20]. The study has implied the advantages of SNP markers in the development of modern plant breeding in pepper with economically important horticultural traits. It can be highly appreciated that the synergistic application of SNP markers along with the modern genomics approaches and NGS technologies accelerates the improvements in the molecular-genomicsassisted plant breeding. The upcoming sections deal with the discovery of SNP markers associated with important traits in pepper
