Characterization of URI1 in Arabidopsis thaliana and its role in stress responses
Gene transcription requires the concerted action of several protein complexes that facilitate the progression of RNA pol II. We have found that the Paf1 complex influences nucleosome accessibility through monoubiquitination of histone 2B.

The plant POLYMERASE-ASSOCIATED FACTOR1 complex links transcription and H2B monoubiquitination genome wide
The study of hormone action requires the development of biosensors that allow fast and quantitative analysis of hormone levels. Here we describe new gibberellin biosensors that work well in plant protoplasts, in collaboration with Matías Zurbriggen (CEPLAS, Germany).

Ratiometric gibberellin biosensors for the analysis of signaling dynamics and metabolism in plant protoplasts
Gibberellins regulate transcription through DELLA proteins. Here we show that one of the mechanisms relies on the ability of DELLAs to stabilize trancriptional complexes via their interaction with Mediator.

Spanish Network on the "Evolution of regulatory mechanisms in development and plant signaling"
SUMOylation is a critical modification that modulates the activity of proteins in all eukaryotes. In collaboration with Ari Sadanandom's group we have connected here the evolution of the SUMO system with developmental innovations in plants.

XVII Reunión de Biología Molecular de Plantas - Castellón de la Plana
A large representation of the lab has attended this year's Spanish Plant Molecular Biology Meeting in Castellón. We presented several posters, and Bruno's was selected for a short talk.

XVII Reunión de Biología Molecular de Plantas - Castellón de la Plana
Our lab received the prize to the best scientific image in the XVII Spanish Meeting of Plant Molecular Biology. The image of RGA protein accumulation at the shoot apical meristem was taken by Antonio and artistically rendered by Mª Eugenia Blázquez.

GIGANTEA adjusts the response to shade at dusk by directly impinging on PIF7 function
Plants respond differently to neighbour-imposed shade depending on the time of the day. We have now found a mechanism that explains this interaction between the circadian clock and the components of the shade response. Find here the details.

Former members of the Plasticity Lab
The Vascular Development and TranslaTOM teams leave the umbrella of the Plasticity Lab. Find more info on their specific activities in their corresponding websites. We will still partner in several research projects.

Light and temperature signals are integrated through a phyB-dependent gene regulatory network in rice
Arabidopsis phytochromes act as photoreceptors and thermosensors. They are the integral component of a small gene circuit that integrates light and temperature signals. In collaboration with Nelson Saibo's Lab in Lisbon, here we show that this integratory circuit is conserved in monocots too.

Shade-induced ROS/NO reinforce COP1-mediated diffuse growth
It had been predicted that the lower photosynthetic activity under shade would generate lower levels of Reactive Oxygen Species. However we have found the opposite! Together with the Casal Lab, we propose that these ROS molecules help the plant adapt their growth under shade.
