Gibberellin requirement for Arabidopsis seed germination is determined both by testa characteristics and embryonic abscisic acid.

Plant physiology - 1 Feb 2000

Debeaujon I, Koornneef M

Abstract excerpt

The mechanisms imposing a gibberellin (GA) requirement to promote the germination of dormant and non-dormant Arabidopsis seeds were analyzed using the GA-deficient mutant ga1, several seed coat pigmentation and structure mutants, and the abscisic acid (ABA)-deficient mutant aba1. Testa mutants, which exhibit reduced seed dormancy, were not resistant to GA biosynthesis inhibitors such as tetcyclacis and...
