Nitrate is absolutely necessary for plant productivity but it also causes lodging, with associated fruit losses. In  collaboration with Jorge Casal's lab in Instituto Leloir (Argentina), we have found a mechanism for this excessive shoot growth. Read about it here.

PIF4 enhances the expression of SAUR genes to promote growth in response to nitrate

Plants and microorganisms have a long-standing relationship. Here we review recent work that identifies how certain mechanisms for the recognition of microorganisms by plants were already present when plants colonized the land.

Plant-pathogen interactions: The need to evolve to stay the same

Cassava is one of the major food sources, especially in subsaharan Africa. In our group we are identifying genes and processes involved in the specification of storage root cell types. Read more here about the involvement of a class-III HD-ZIP transcription factor that we have found.

Identification of MeC3HDZ1/MeCNA as a potential regulator of cassava storage root development

Xylem formation relies of precise translational regulation of certain transcripts by thermospermine. Here we describe an easy quantitative method to measure translational efficiency.

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.

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.
