MetabolomicsFruit setting rewires central metabolism via gibberellin cascades
Fruit set is the process whereby ovaries develop into fruits after pollination and fertilization. The process is induced by the phytohormone gibberellin (GA) in tomatoes, as determined by the constitutive GA response mutant procera However, the role of GA on the metabolic behavior in fruit-setting o...

TranscriptomicsNatural variation of gibberellin responses in Arabidopsis thaliana
To assess natural variation in the ability to respond to changes in gibberellin metabolism, we examined the effect of the ectopic expression of GA20ox1 in 10 Arabidopsis thaliana accessions. RNA-seq was performed on the sixth leaf, which was micro-dissected (size < 0.25 mm2) at the beginning of the ...

TranscriptomicsTranscription profiling of Arabidopsis early gibberellin responses
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 n...

TranscriptomicsTranscription profiling of Arabidopsis transgenic lines with a gibberellin non responsive DELLA protein vs control to identify DELLA protein direct targets
The aim of this study is to identify early DELLA protein-responsive genes using a Dexamethasone (DEX)-inducible system. Two transgenic lines were used: one induces the expression of a dominant, gibberellin non-responsive DELLA protein (rga-delta17); the other is a control line that carries the same ...

TranscriptomicsBrassinosteroid, gibberellin, and phytochrome impinge on a common transcription module in Arabidopsis
Brassinosteroid (BR) and gibberellin (GA) promote many similar developmental responses in plants; but their relationship remains unclear. Here we show that BR and GA act interdependently through a direct interaction between the BR-activated BZR1 and GAinactivated DELLA transcription regulators. GA p...

TranscriptomicsGenome-wide identification of Vitis vinifera microRNAs reveals their differential regulation by gibberellin
MicroRNAs (miRNAs) play a important part in post-transcriptional gene regulation and have been shown to control many genes involved in various biological and metabolic processes. There have been extensive studies to discover miRNAs and analyze their functions in model plant species, such as Arabido...

TranscriptomicsNext Generation Sequencing of tomato WT, M82 and pro∆GRAS mutant treated with Gibberellin
The goal of this study was to search for DELLA-independent GA-regulated genes in tomato. RNA deep sequencing (RNA-seq) was performed to GA-treated M82 and pro∆GRAS mutant. Using a two fold increased or decreased cutoff we identified 81 GA-up regulated and 15 GA-down regulated genes, from which five ...

TranscriptomicsTranscriptome changes associated with relief of sly1-2 seed dormancy through after-ripening or overexpression of the gibberellin-receptor GID1b
Seed dormancy is the inability for seeds to germinate even under favorable conditions. In the Arabidopsis Landsberg erecta (Ler) ecotype, 2 weeks of dry storage, called after-ripening, is sufficient to relieve seed dormancy. Such seed is referred to as after-ripened (AR) and has a hi...

TranscriptomicsTranscription profiling of Arabidopsis thaliana early response to the phytohormone Gibberellin (GA)
The phytohormone GA controls multiple important developmental processes in plants such as germination, elongation growth and flowering time. In this experiment, we look for early GA response genes in 7 day-old light-grown Arabidopsis seedlings. To this end we compare four data sets: (1) a GA biosynt...
