“…Other hormones, such as cytokinin (CK), brassinosteroid (BR), and gibberellin (GA), are also involved in regulating ovule initiation and contribute to gynoecium size and ovule number (Bartrina et al, 2011; Huang et al, 2013; Gómez et al, 2018). These hormones can work both independently and through crosstalk with each other to influence ovule initiation (Cucinotta et al, 2014; Marsch‐Martínez and de Folter, 2016; Deb et al, 2018; Cucinotta et al, 2020; Qadir et al, 2021; Yang and Tucker, 2021). The molecular mechanisms by which individual hormones regulate ovule initiation, as well as some crosstalk between hormones, have been well summarized in previous reviews (Cucinotta et al, 2014; Cucinotta et al, 2020; Barro‐Trastoy et al, 2020b; Qadir et al, 2021; Yang and Tucker, 2021).…”
