Arabidopsis seeds

ABA produce more mature seeds showing primary dormancy than the wild-type plants. A reduced dormancy often occurs in seeds of ABA-insensitive mutants. Gibberellin A (GA) is absolutely required for germination of the wild-type Arabidopsis seeds. Seeds of ethylene-insensitive and GA-insensitive mutants are supersensitive to exogenous ABA, which suggests that in imbibed seeds ethylene and GA may directly counteract the action of ABA in dormancy maintenance. ...

The identification and isolation of genes involved in flavonoid biosynthesis has benefited from the fact that many of the flavonoids are colored compounds. Mutant phenotypes are therefore often easily identifiable based on variation in color. In Arabidopsis many of the genes involved in flavonoid bioysnthesis have been uncovered based on the change in seed coat (testa) color. Wild-type Arabidopsis seeds have a brown color, and mutations in flavonoid biosynthetic genes result in yellow or pale brown color because the underlying cotyledons are visible. These mutants are referred to as...

The concentration of ABA increases in late embryo development shortly before the onset of desiccation and seed dormancy [42,81], ABA inhibits precocious germination of immature embryos in culture [70]. Genetic studies have shown that ABA is involved in dormancy and ABA deficient and ABA-insensitive mutants have been isolated [44]. Reciprocal crosses of wild type and ABA-deficient aba mutants of Arabidopsis showed that there are two different pools of ABA in Arabidopsis seeds. The embryonic ABA is...
