Seed dormancy is a common phase of the plant life cycle, and several parts of the seed can contribute
to dormancy. Whole seeds, seeds lacking the testa, embryos, and isolated aleurone layers of
Arabidopsis (Arabidopsis thaliana) were used in experiments designed to identify ...

Abscisic acid (ABA) is a plant hormone that regulates seed dormancy and germination. Seeds
undergo changes in both ABA content and sensitivity during seed development and germination
in response to internal and external cues. Recent advances in functional genomics have ...

Endogenous abscisic acid (ABA) levels are regulated by both biosynthesis and catabolism of
the hormone. ABA 8'-hydroxylase is considered to be the key catabolic enzyme in many physiological
processes. We have previously identified that four members of the Arabidopsis ...
