Plant development is coordinated with the environment to maximize growth and survival. We investigate mechanisms of plant response to environmental signals with the potential biotechnological application in agriculture.

 

Hypothesis: “Periodic genes are the first layer of environmental surveillance that guides plant developmental transitions, growth dynamics, and stress responses”

 

Our Approach: We investigate the function and molecular mechanism of periodic genes in poplar tree model. We apply genetics (CRISPR/Cas9), genomics, molecular and cell biology tools on poplar model tree. We focus on poplar homologs to Arabidopsis genes with roles in:

 

  1. Flowering time regulators
  2. Circadian clock regulators
  3. Light signaling mediators

2019. PGC2018-093922-B-I00 – REACTIOn - MICIU

 

 

 

Hypothesis: “It is possible to bioengineer or biostimulate seasonal bud break and flowering in perennials”

Our Approach: We look for seasonal regulators and metabolites that promote shoot apical meristem growth reactivation. We focus on differential expressed genes, proteins, and metabolites obtained through:

  1. Transcriptomic and methylome studies
  2. Proteomic studies
  3. Non targeted metabolomic studies
  4. Chemical screening
  5. Plant phenological and biostimulation assays
