“…Additionally, it has been shown that several Cys-rich peptides also have a role in plant development, pollen recognition and guidance, and seed development (Marshall et al, 2011;Qu et al, 2015) (Figure 2). In this section, we highlight some typical representatives of those Cys peptides, but refer to excellent recent reviews for a more complete overview on Cys-rich peptides (Marshall et al, 2011;Beale and Johnson, 2013;Richardson and Torii, 2013;de Souza Cândido et al, 2014;Murphy and De Smet, 2014;Nawrot et al, 2014).…”
