ARCHI - Plant architecture and functioning

Keywords
Morpho-anatomy
Ontogeny
Plasticity
Adaptation

Understanding the "structure-function-time-environment" relationships that govern the three-dimensional development of individual plants along ontogeny, according to the architectural approach initiated in the 1970s by F. Hallé et R. Oldeman (Hallé et al. 1978 - Tropical Trees and Forests - An Architectural Analysis. Springer).

In order to understand the functioning, evolution and adaptation of plants, we develop research on : (i) the links between architectural attributes and functions ("functional traits") related to exploration (occupation of space), assimilation (photosynthesis, root absorption), transport (flow, cavitation), reserves (role of parenchyma, water storage), support (mechanical support and postural control), defence (heartwood formation, morpho-anatomical adaptations), and survival strategies via vegetative and/or sexual reproduction ; (ii) the functional role of anatomy in the broad sense (pith, wood, bark, leaves...); (iii) the evolution of plant architecture, from fossil plants to phylogenies based on contemporary species and their biogeography (heterochrony, radiation, architectural convergences and divergences).
This work is based on : the study of growth forms (trees, shrubs, bushes, epiphytes, lianas); the morpho-anatomical analysis of the fundamental organisation of the plant (architecture, regularities, similarities) and the functioning of the shoots (stem-petiole-limb interface) and the tree crown; the relationships between primary and secondary growth, between stem and root development; the study of the multifunctional role of wood (mechanical support and hydraulic conduction), the determinants and the role of the epicormic branches (repair mechanisms).
Plants are also studied in their environment through the relationships between architecture, functional traits and biotic factors; interactions between individuals within the stand and communities (competition for resources, forest succession).
This work has applied spin-offs for the selection of species or varieties in agronomy and forestry; the development of diagnostic tools for tree management in cities, monitoring forest health; the definition of sampling protocols for the structure of large forest canopies, the determination of ontogenetic stages (architectural stages), or the measurement of functional traits in community ecology.

Several of our projects are conducted in French Guiana (partly supported by LabEx Ceba, and in New Caledonia, partly supported by IRD infrastructure and the Herbarium of New Caledonia).
