“…Prior studies have shown that transgenic plants that have an expanded RSA have improved water homeostasis (Hetherington & Woodward, ; Malamy, ; Masle, Gilmore, & Farquhar, ; Yu et al, ). As a major environmental stress, drought imposes adverse effects on plant growth and development (Denby & Gehring, ; Liu, Qin, Han, Xiang, & Zhao, ; Tan, Li, & Ma, ). Plants need to reallocate energy to increase stress tolerance, and they adjust growth and development during stress‐inducing conditions (Ahuja, de Vos, Bones, & Hall, ; Skircyz & Inzé, ) using diverse mechanisms for coping at the morphological, anatomical, and cellular levels (Bray, ).…”
