“…Cucumber ( Cucumis sativus L.) is a horticultural crop that is consumed worldwide (Huang et al, 2009; Yundaeng et al, 2015), and trichomes (spines) on the fruit are considered as an important commodity trait (Zhang et al, 2010; Yang et al, 2014; Li et al, 2015; Pan et al, 2015). The cucumber fruit, a pepo that develops from the ovary and receptacle, is covered with a thick cuticle, tubercules and trichomes (spines) (Roth, 1977; Wang et al, 2015). In the model plant Arabidopsis thaliana , trichome developments is initiated by a ternary complex ( GL1-GL3/EGL1-TTG1 ) from epidermal cells, which leads to the expression of GL2 and TRY (Oppenheimer et al, 1991; Galway et al, 1994; Walker, 1999; Payne et al, 2000; Szymanski et al, 2000; Larkin et al, 2003; Zhang et al, 2003).…”
