I graduated in Biology (Universitat de València) and obtained my PhD in the laboratory of Jose Luis Garcia-Martinez (IATA-CSIC, València). In 1993 I moved to work with plant transcription factors in Cathie Martin’s group (JIC, Norwich, UK). In 1996 I was part of Peter Quail’s team (PGEC, UC-Berkeley, USA) to work on phytochrome signaling in Arabidopsis. After a short stay in Dr. Prat lab (IBMB-CSIC, Barcelona) working on photoperiod-regulated potato tuberization, in 2001 I joined ICREA to establish my own research line on light control of plant development. Currently, I am a group leader at the Center for Research in Agricultural Genomics (CRAG, Consortium CSIC-IRTA-UAB-UB), in Barcelona, working in the shade avoidance syndrome in Arabidopsis and related species, a light response of enormous biotechnological and agricultural importance.

Research Interests
|
|
We are interested in understanding how plants, after perceiving vegetation proximity, change development to compete for their main and basic resource: light. In shade avoiding species, such as Arabidopsis thaliana, these responses are known as the shade avoidance syndrome (SAS). We are analyzing the molecular and genetic mechanisms behind the SAS responses in the model plant A. thaliana, that involve the modulation of pre-existing transcriptional networks by specific photoreceptors.
Other plants, such as Cardamine hirsuta (a close relative of A. thaliana), tolerate plant proximity. We have postulated that in shade tolerant species vegetation proximity perception by photoreceptors is wired up differently to these pre-existing transcriptional networks. Therefore, we are carrying out comparative analyses between C. hirsuta and A. thaliana as a way to dissect the genetic and molecular basis for differences in shade avoidance vs. shade tolerant species.
