Gibberellins: Biosynthesis and Methods| Plant Hormones

Brassinosteroid and gibberellin promote many similar developmental responses in plants; however, their relationship remains unclear.

The biosynthesis of gibberellins requires the action of plastid‐localised terpene cyclases, membrane‐bound cytochrome P450 monoxygenases and soluble 2‐oxoglutarate‐dependent dioxygenases.

The hormone-mediated control of plant growth and development involves both synthesis and response. Previous studies have shown that gibberellin (GA) plays an essential role in Arabidopsis seed germination. To learn how GA stimulates seed germination, we performed comprehensive analyses of GA biosynthesis and response using gas chromatography–mass spectrometry and oligonucleotide-based DNA microarray analysis. In addition, spatial correlations between GA biosynthe-sis and response were assessed by in situ hybridization. We identified a number of transcripts, the abundance of which is modulated upon exposure to exogenous GA. A subset of these GA-regulated genes was expressed in accordance with an increase in endogenous active GA levels, which occurs just before radicle emergence. The GA-responsive genes identified include those responsible for synthesis, transport, and signaling of other hormones, suggesting the presence of uncharac-terized crosstalk between GA and other hormones. In situ hybridization analysis demonstrated that the expression of GA-responsive genes is not restricted to the predicted site of GA biosynthesis, suggesting that GA itself, or GA signals, is trans-mitted across different cell types during Arabidopsis seed germination.
