The UV research groups (GIUV) are regulated in the 1st chapter of the Regulation ACGUV48/2013, which explains the procedure for creating new research structures. They are basic research and organizational structures that result from the voluntary association of researchers that share objectives, facilities, resources and common lines of research. These researchers are also committed to the consolidation and stability of their activity, work in groups and the capability to achieve a sustainable funding.
The research groups included in the previously mentioned Regulation are registered in the Register of Research Structures of the Universitat de València (REIUV), managed by the Office of the Vice-principal for Research and Scientific Policies. The basic information of these organisms can be found in this website.

Reference of the Group:
Description of research activity: This group explores the molecular mechanism underlying sexual reproduction of flowering plants.
With a focus on gamete interaction, in previous projects we have isolated plant gametes from Arabidopsis thaliana and Solanum lycopersicum (tomato) to generate highly specific transcriptomic and proteomic datasets of these special cells under normal and heat stress conditions. These results give us the possibility to integrate, identify, and characterize new molecular players involved in double fertilization and how abiotic stress impacts this process.
In addition, we study the molecular program of other economically important processes related to plant reproduction, like parthenocarpy (fruits without seeds) and apomixis (seeds without fertilization) in collaboration with other national and international groups.
The identification of essential genes involved in those processes and its conservation in crops represent the possibility to manipulate in our favor the reproductive process, and consequently guarantee our main source of food.

Scientific-technical goals: - To characterize new genes involved in gamete interaction and double fertilization.
- To identify putative genes in plant gametes related to heat-stress resilience during sexual reproduction.
- To contribute to elucidate the molecular mechanism of parthenocarpic and apomictic egg cells of specific crops.
Research lines: - Plant gamete biology and interaction.Identification and characterisation of specific genes in sperm cells and female gametes involved in gametic interaction.
- Abiotic stress and sexual reproduction.To explore the impact of heat stress during progamic phase in tomato and Arabidopsis.
- Parthenocarpy and apomixis.Generation of omic datasets from plant gametes of relevant parthenocarpic crops.
