Early gibberellin responses in Arabidopsis

The aim is to identify early gibberellin responsive genes in a gibberellin deficient strain such as ga1-3. Such genes are likely regulated by DELLA proteins which are master gibberellin repressors. DELLA proteins are rapidly degraded after gibberellin treatment, but their direct target genes still need to be elucidated. Keywords: hormone response, gibberellin treatment A set of 4 biological replicates was generated for each treament. Arabidopsis seedlings were treated with water or 2 uM GA4 and whole shoots collected after 1h. A comparison of water vs. GA4 treated samples should render a list of early gibberellin responsive genes.
