Abstract:

High-throughput plant phenotyping aims at capturing the genetic variability of plant responses to environmental factor for thousands of plants, in order to identify heritable traits for genomic selection and predict the genetic values of allelic combinations in different environments. This implies the automation of the measurement of a large number of traits (to characterize plant growth, plant development and plant functioning), which can now be performed using phenotyping platforms (such as the seven facilities of the French plant phenotyping network Phenome). These platforms produce massive data sets (plant imaging, climatic information, from 150 to 200 Terabytes of data per year in Phénome) that must be analyzed to understand interactions between genes and environment (GxE) and possibly predict crop performance.

Thus, it has become critical to couple the design of flexible, adaptable, and dynamic evolving plant response models with these massive data sets. The challenge lies in efficiently analyzing huge and complex datasets while keeping such in-silico experiments reproducible. To deal with massive data sets, we need to exploit powerful computing environments in a way that is easy for the users, without requiring them high-technical knowledge. The goal of this thesis is to address two critical issues in the management of plant phenotyping experiments: (i) schedule distributed computation while considering many constraints and (ii) allow reuse and reproducibility of experiments by biologists. These methodological developments will be applied to scientific workflows for 3D shoot architecture reconstruction, implemented in the OpenAlea platform, and used in the Phénome project.
