From: Gibberellin in tomato: metabolism, signaling and role in drought responses
Low GA activity promotes drought resistance in tomato via several mechanisms. Low GA levels or activity promote ‘drought tolerance’ by osmoregulation (Omena Garcia et al., 2019). It also promotes ‘drought avoidance’ by inhibiting canopy growth, accelerating stomatal closure, reducing xylem expansion and proliferation and increasing root to shoot ratio (Nir et al., 2014,2017; Illouz Eliaz et al., 2020; Ramon et al., 2020; Shohat et al., 2020, 2021)
