Tomato introgression lines

QTLs were also detected in tomato introgression lines (domestic tomatoes with single, defined chromosome regions selected from the progeny of a cross with a wild, non-pigmented variety) that correspond to candidate loci for which genes and mutants have been previously characterized. Detected QTLs included the r locus Psy), the Del locus (LcyE), and the B locus. Similar to the tissue-specific expression of maize Yl, the B locus codes a fruit-specific lycopene cyclase associated with higher levels of P-carotene. ...
