Root Phenotyping Platform

 

The Root Phenotyping Platform, created in 2017, is hosted by the « Biochemistry and Plant Molecular Physiology » department. It is dedicated to kinetic and non-destructive analysis of seedling Root System Architecture of many species including Arabidopsis, rice, tomato, rapeseed, and Medicago grown in vitro. The main objective of the platform is to develop approaches, tools and methods to characterize the impact of different growth environments on root growth and development. This includes osmotic stresses, nutrient deficiency or excess or biotic interactions alone or in combination. These analyses provide the basis for further genetic and molecular physiology approaches.

Seedling are grown in vitro on 120x120mm (Small plates: SP) or 245x245mm (Large plates: LP) Petri dishes. The phenotyping facility includes a self-contained imaging unit that can handle up to 72 LP and 200 SP at once with imaging frequency ranging from 2 to 24 hours.

The imaging automat is located in a dedicated growth chamber allowing temperature, hygrometry, photoperiod, light intensity being adjusted according to user’s requirements.

 

It is equipped with a 16Mpixel linear camera, a telecentric objective and collimated LED backlight for images at 10µm resolution with high contrast (even for thin and almost translucent Arabidopsis roots).

Collected images are stored on long term on a secure data storage system.

Images are analyzed through semi-automated or fully automated pipelines integrated in the OpenAleaLab suite (https://team.inria.fr/virtualplants/software/). The Root Phenotyping Platform is backed to B&PMP research programs but is open to the scientific community through local, national and international collaborations

Access
  • Access to the phenotyping platform is through scientific collaborations.
  • Applications should be done via the « Application form » and emailed to nacry@inra.fr. Applications will be evaluated by the platform steering committee. Once a decision has been notified, get in touch with Philippe Nacry (philippe.nacry@inra.fr) for organizing the schedule and experiments.
