“…Large‐scale QTL identification and genome‐wide association study (GWAS) strategies have been previously adopted to detect QTLs or genes associated with the control of variations in CAPD content among inter‐ and intraspecific varieties, and the detected QTLs varied among the populations used for analysis (Blum et al ., ; Ben‐Chaim et al ., ; Ogawa et al ., ; Nimmakayala et al ., ; Han et al ., ). Although the functions of AT3 , Kas , CoMT , AMT and CaMYB31 are related to CAPD biosynthesis (Stewart et al ., ; Abraham‐Juarez et al ., ; Gururaj et al ., ; Arce‐Rodríguez & Ochoa‐Alejo, ), only a few CAPD content‐related QTLs have been cloned and functionally verified based on fine mapping (Cheng et al ., ; Lee et al ., ; Nimmakayala et al ., ; Han et al ., ). Recently, recombinant inbred lines (RILs) and F 2 plants derived from a cross between the nonpungent C. annuum accession ‘YCM334’ and the pungent C. annuum cultivar ‘Tean’ were used to identify the nonpungency locus Pun3 on chromosome 7 (Han et al ., ).…”
