Moving abscisic acid transport forward

Abscisic acid (ABA) transport in plants is necessary to regulate developmental plasticity and responses to environmental signals. Plants use ABA exporter ATP-binding cassette G25 (ABCG25) to control ABA homeostasis. Three recent papers (Huang et al., Ying et al., and Xin et al.) have revealed the structure and transport mechanism of ABCG25.
