A central role of abscisic acid in stress-regulated carbohydrate metabolism.

<h4>Background</h4>Abiotic stresses adversely affect plant growth and development. The hormone abscisic acid (ABA) plays a central role in the response and adaptation to environmental constraints. However, apart from the well established role of ABA in regulating gene expression programm...
