Tomato roots growth adaptation to drought
The role of abscisic acid (ABA) in regulating root (primary root elongation and lateral root number) under soil drying and after re-watering remains unclear. By using wild-type (WT) and ABA-biosynthesis mutant (not) tomato plants, we addressed the morphological and molecular mechanisms that endogenous ABA regulates root growth via auxin-dependent processes.
