| Research Abstract |
Abscisic acid (ABA) is a plant hormone that plays important roles on the regulation of seed dormancy and germination. By using mass spectrometry, we revealed that ABA is synthesized both in maternal and zygotic tissues, and ABA synthesized in maternal tissues is transported to the embryos during Arabidopsis seed development. We identified genes regulated by ABA in tissue specific manners by microarray analysis, and showed that ABA synthesized in different tissues has different physiological functions.
