Node 9: Nantes Omic, Phenics

Research Unit UR1268 Biopolymers Interactions Assemblies (BIA)

Phenics evaluates the quality of plant raw materials, especially seeds. The installation has developed approaches and tools for screening the internal seed structure (multispectral imaging) as well as chemiotyping the major constituents of seeds (starch, cell wall polysaccharides, fibers, α-galactosides, proteins). Throughputs are 300 genotypes per day for structural phenotyping and 1000 genotypes per year for chemotyping.

A high-throughput facility allows the screening of plant organs based on multispectral imaging (structural phenotyping) and biochemical analyses of biopolymers (chemical phenotyping / chemotyping). It is specialized in the mapping of grain constituents and in the composition and the structure of biopolymers such as starch, proteins and cell-wall polysaccharides. Structural phenotyping, based on multispectral imaging, is currently applied to seeds, such as wheat, barley, maize, pea and rice.

Chemical analysis is applied to various plant derived-samples such as fruits, vegetables, legumes, algae, leaves, grains, seeds, stems. Phenochem is also a component of the BIBS platform at INRA of Nantes
