How do natural populations of plants adapt to water limitation? Here we show that they tend to be smaller: not only they lose less water in absolute values, but they are more efficient in water usage. Nice collaboration led by Carlos de Ollas and Aurelio Gómez-Cadenas at UJI.

Plant size directly correlates with water use efficiency in Arabidopsis

Plant hormones very often exert different functions in different organs, tissues or cell types. Here we review the basic mechanisms by which this spatial regulation is imposed and discuss several examples.

Spatial regulation of plant hormone action

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.

Spatial regulation of thermomorphogenesis in plants

We start SPATHERM, a joint effort to study organ- and cell-type specific temperature responses in plants, funded by the PROMETEO program of Generalitat Valenciana. The team includes Maite Sanmartín, Cristina Úrbez, José León, Javier Agustí, David Alabadí and Miguel Blázquez, all at IBMCP.

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!!

Horizon Europe-MSCA-PF "DELLAsFixGenome"

Congratulations, Yaiza! A new PhD achieved in our group. Thanks also to the Committee members: Elena Baena, Cristina Martínez and Javier Brumós.

"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.

DELLA proteins recruit the Mediator complex subunit MED15 to coactivate transcription in land plants
