Phenoscope platform



The Phenoscope is a high-throughput phenotyping device to handle and monitor hundreds of individual pots, each containing a single plant. It is typically used to track vegetative growth under various environments on a large number of genotypes. The pots are rotated continuously (typical cycle of 4 hours) on a closed-circuit track consisting of a series of switchback turns that allow the 700+ plants to be exposed to very homogeneous conditions. Weighing / watering stations allow to monitor and adjust watering and nutrients at every cycle following precise scenarios defined by the user for each pot, while imaging stations are designed to acquire non-destructive phenotypes in the visible and IR range. The Phenoscope is specifically designed to handle small plants (Arabidopsis) during their vegetative phase and is not (yet) intended to monitor growth in 3D or handle plants beyond flowering initiation. We have shown that the average gain enabled by the Phenoscope (in terms of reduction in the environmental heterogeneity or in the number of replicates needed) was about a factor 3.


=> These robots allow to perform experiments that would not be viable or reproducible by hand.



Phenoscopes are typically best exploited in quantitative genetics approaches (QTL, GWAS), mutant screens or any other large scale experiment that require the comparison of hundreds of individuals in different environments. They can also be useful for a detailed characterisation of a small number of specific lines (in comparison with other datasets present in our database) and for the establishment of response curves against multiple gradual stress treatments.


There are only 4 of these robots in the community, all at IJPB (INRA Versailles) as part of the Plant Observatory (Observatoire du Végétal). They are placed in 2 distinct growth chambers with contrasted lighting (either fluorescent or white LED lights). Environmental settings are constrained and we strongly favor experiments in our standard conditions, i.e. short days (= 8h photoperiod) and standard temperature (21°C/18°C) and hygrometry (65%).



The Phenoscope™ is filed under an INRA patent.
