Various aspects of plant development are controlled by plant hormones, which have been extensively studied. In recent years, however, considerable progress has been made in the study of their action during development and ripening in dry fruits as well as fleshy fruits. A complex network of more than one plant growth hormone is involved in controlling various aspects of fruit development, and there is growing evidence that the relative role of plant hormones is not limited to a particular stage. Despite the extensive coverage in some areas, gaps remain in our understanding of hormonal networks and the interplay between different hormones during fruit growth, maturation, and other aspects of ripening. To understand their mechanism of action in fleshy fruits, we examine the relative role of plant hormones in tomato fruit development. To gain a deeper understanding of hormonal crosstalk during fruit development in other species, pertinent pieces of evidence are also discussed.
