Here is a post about our recent publication investigating the link between stomatal closure and embolism resistance


co-authors: Nicolas Martin-StPaul and Hervé Cochard

Main output: All species close stomata before -4MPa: read the paper here

Aridity drove the evolution of extreme embolism resistance and the radiation of conifer genus Callitris.

Our results provide strong evidence that the evolution of extreme xylem embolism resistance accompanied the radiation of the Callitris clade and was driven by the aridification of the Australian continent during the last 30 million yr. link

INRA Laurel Wreath for Excellence

I was awarded the INRA Laurel Wreath for Excellence by Thierry Mandon, French Minister of State for Higher Education and Research, and François Houllier, President of INRA in December 2015, after selection by an international committee. This early career award was obtained for my work on resistance to drought in trees, within the broader scope of research on the adaptation of forests to climate change.

Leaf hydraulics:  wicked easy (Fingers in the nose)


Visualizing embolism in Laurel leaves

Bruny island 2016


By imaging a laurel leaf at 3 min intervals and by subtracting the difference between the images to see where an embolism formed, we were able to determine at which water potential laurel leaves cavitate. Images were colorized by how much time had elapsed and combined to give a complete picture of the plant’s response to water stress.


This new technique to measure resistance to water stress was developped by Brodribb et al (2016) and is now running at the GENOBOIS Platform Caviplace.


This study was conducted by Déborah Corso, Laurent J Lamarque, Gaëlle Capdeville, José Manuel Torres Ruiz, Régis Burlett and Sylvain Delzon.


It has been carried out with financial support from the French National Research Agency (ANR) in the frame of the Investments

for the future Programme, within the Cluster of Excellence COTE (ANR-10-LABX-45).

Coming soon!!!



We might be able to measure 1m long samples; but not so sure… if not Jarmila suggested to put in on wheels, drag it to the town square and charge admission for rides!
