Phytochromes are red/far red photosensors regulating numerous developmental programs in plants. Among them phytochrome A (phyA) is essential to enable seedling de-etiolation in continuous far-red (FR) light a condition mimicking the environment under a dense canopy. The ecological relevance of this ...

Arabidopsis fc2-1 mutants fail to properly de-etiolate after a prolonged period in the dark. Our goal was to monitor whole genome expression during the first 2 hours of de-etiolation to determine the cuase of this growth arrest. In comparison with other mutants that also affect de-etiolation, we ide...

De-etiolation consists of a series of developmental and physiological changes that a plant undergoes in response to light. During this process light, an important environmental signal, triggers the inhibition of mesocotyl elongation and the production of photosynthetically active chloroplasts, and e...

Light triggers chloroplast differentiation whereby the etioplast transforms into a photosynthesizing chloroplast and the thylakoid rapidly emerges. However, the sequence of events during chloroplast differentiation remains poorly understood. Here we used whole-seedling proteome data to quantify chan...

Lysine acetylation is one of the most important post-translational modifications and is involved in multiple cellular processes in plants. There is evidence that acetylation may play an important role in light-induced de-etiolation, a key developmental switch from skotomorphogenesis to photomorphog...

Tissue specific light response during Arabidopsis de-etiolation
The dramatic switch from skotomorphogenic to photomorphogenic development is an excellent system to elucidate both light signal transduction pathways and rapid developmental response to environmental stimuli in plants. To decipher the effects of various wavelengths of light on de-etiolation, we illu...
