Metabolite biodiversity in pepper (Capsicum) fruits of thirty-two diverse accessions: Variation in health-related compounds and implications for breeding

Genome sequence of the hot pepper provides insights into the evolution of pungency in Capsicum species

“…Pepper fruit is one of the richest sources of ascorbate. The concentration of ascorbate in pepper is up to tenfold higher than in tomato 58 . Most of the pepper genes in the l-galactose pathway showed expression similar to or higher than in tomato (Supplementary Table 56).…”

An InDel in the Promoter of Al-ACTIVATED MALATE TRANSPORTER9 Selected during Tomato Domestication Determines Fruit Malate Contents and Aluminum Tolerance

“…With the currently available high-throughput genotyping technologies, genome-wide association studies (GWAS) have been developed as a powerful approach to characterize the genetic basis of complex traits and locus-locus interactions in plants (Nordborg and Weigel, 2008). More recent studies combining GWAS with metabolomics (mGWAS) demonstrate a powerful forward genetics strategy that can be used to dissect the genetic and biochemical basis of plant metabolism, including that in model species, such as Arabidopsis thaliana, tomato, rice (Oryza sativa), and Medicago truncatula, and other crop species, such as barley, perilla (Perilla ocymoides), and pepper (Capsicum annuum) (Achnine et al, 2005;Yamazaki et al, 2008;Widodo et al, 2009;Wahyuni et al, 2011;Carreno-Quintero et al, 2013;Luo, 2015). Moreover, recent studies have revealed that linkage disequilibrium mapping in combination with linkage mapping improves the ability to identify important loci.…”

Metabolomics as a Tool in Agriculture

“…Also in this family, the metabolic proile from the fruit of chili (Capsicum sp.) was determined to study its diversity, using HPLC-PDA/LC-PDA-QTOF-MS-MS [68].…”
