Phenology of temperate woody perennials is determined by the environment. Long days and warm temperatures promote growth. Day shortening and a drop of temperatures induce dormancy, but once established, growth cannot resume until a minimal requirement of cold hours has been satisfied. Moreover, tree acclimation to seasons involves the activation of adaptative mechanism related to plant stress tolerance. Understanding woody perennials response to the environment will contribute with an efficient vegetative and reproductive tree growth, reduce economic costs in tree management, and improve productivity, adaptation and geographical distribution.

 

Poplar is regarded as a model temperate tree species in forest genetics, genomics, physiology and phytoremediation. Poplar (Populus spp.) is a genus of fast growing trees with economic importance for biomass production worldwide. We aim to understand fundamental mechanisms determining environmental control of poplar development for engineering the best climate-smart genetic material to develop plus trees. To achieve that, we are investigating the following processes:

 

 

PHOTOPERIODISM and LIGHT SIGNALING


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


Our Approach
: We investigate the function and molecular mechanism of periodic genes (diurnal and circadian) in poplar tree model. We apply genetics (CRISPR/Cas9), genomics, molecular and cell biology tools, and computational modeling in collaboration with Dr. K. Wabnik laboratory (CBGP, UPM-INIA/CSIC). We focus on poplar homologs to Arabidopsis genes with roles in:

 

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

 

 

 

TERMORESPONSE and DORMANCY REGULATION


Hypothesis:It is possible to bioengineer or biostimulate seasonal dormancy break and flowering in perennials

 

Our Approach: We look for seasonal regulators and metabolites that promote shoot apical meristem growth reactivation. We focus on thermoresponsive 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

 

 

 

POPLAR TREES FOR ZEROPOLLUTION


Hypothesis:Stress related transcription factors can improve poplar heavy metals phytoextraction from polluted soil

 

Our Approach: We investigate the phytoextraction potential of poplar overexpressing and knock out lines of stress-related transcription factors. Physiology and genomic of heavy metal accumulation are investigated to understand and improve poplar phytoextraction molecular mechanism. This project is developed in collaboration Dr. Michel Chalot laboratory (UBFC, France) and the bioremediation experts Horizon BIOSYSMO consortium.

 

 

 

 

UNDERSTANDING SECONDARY VASCULAR AND STOMATAL DEVELOPMENTAL PLASTICITY UNDER SEVERE DROUGHT


Hypothesis:It is possible to bioengineer drought tolerant poplars by manipulating shoot vascular and stomatal development


Our Approach:
We are implementing scRNA-Seq to identify unique cell types, states, and responses on a single- cell level of poplar under well irrigated and severe drought conditions. Using snRNA-seq pipeline, we will define complex regulatory networks that change in response to stress, providing a map to uncover critical mechanisms of cell specific drought stress tolerance in trees.  This work is conducted by Dr. Daniel Conde junior leader La Caixa in CBGP (https://www.cbgp.upm.es/index.php/es/?option=com_content&view=article&id=945) and Dr. Matias Kirst laboratory UF, USA

 

 

SHOOT-ROOT SIGNALING


Hypothesis:Light signaling modulate development of the root system, its function and response to drought

 

Our Approach: We investigate the effect of the light quality and/or quantity signaling on poplar root system development using root clock luciferase reporter lines. We take advantage of CRISPR mutants of shoot light signaling regulators created in our laboratory to explore the effect on light quality and quantity on root development and function in collaboration with Dr. Moreno-Risueño laboratory (CBGP, UPM-INIA/CSIC).
