Fig. 3From: Applications of CRISPR/Cas genome editing in economically important fruit crops: recent advances and future directionsStrawberry fruit structure and a model illustrating the regulatory pathway during fruit initiation and growth. A Double fertilization promotes biosynthesis of auxin and GA in the seed. Auxin and GA can stimulate receptacle development after being transported to the receptacle. B A diagram of receptacle illustrating the regulatory mechanism of fruit set. FveRGA1 is shown as a central player. The red lines indicate regulatory actions post-fertilization. Positive (arrows) or negative (bar) regulations are indicated. Adapted from (Feng et al. 2019; Zhou et al. 2021; Guo et al. 2022)Back to article page
