al., 2006 ; Li et al., 2003 ). In tomato, two putative cobra-like genes are present within a quantitative trait locus ( fw3.2 ) associated with the control of fruit weight ( Zhang et al., 2012 ). The α−type expansin genes encode for proteins

NCED result in small quantities of carotenoids in yellow and white fruit. The LCYB gene has been reported as a major quantitative trait locus (QTL) that could increase the lycopene content in watermelon ( Liu et al., 2015 ). Obviously, these studies
