We have been awarded three grants in the latest national AEI call. Antonio will lead a study on the characterization of meristem responses under drought stress; David the participation of chaperone-like proteins during heat stress; and Miguel the evolution of light and temperature sensing in land plants.

Big hurray for Anna Solé-Gil, the new doctor from our group. She has just defended her Thesis with nice work on Marchantia and other species, and with Selena Giménez, Sandy Hetherington and Isabel Monte in the PhD Committee.

Origin and evolution of the C3HDZ-ACL5-SACL regulatory module in land plants
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.

Quantification of xylem-specific thermospermine-dependent translation of SACL transcripts with dual luciferase reporter system
Our postdoc Victoria Gastaldi has just been awarded a Marie Curie Fellowship to extend her stay in the lab. Congratulations, and good luck!!

"Analysis of shoot stem cells activity under abiotic stress conditions"
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.
