More than 200 articles in WoS registered journals and up to dozens of chapters in monographs or monographs are published by the authors from the IB every year. Here, we present only a selection of some interesting results.

1/ Plant community stability is associated with a decoupling of prokaryote and fungal soil networks
Soil microbiota plays a crucial role in maintaining plant community stability. We found that plant communities on former agricultural soil promoted destabilising properties and were associated with coupled prokaryote and fungal soil networks. Conversely, plant communities on natural grassland soil exhibited high stability, associated with decoupled prokaryote and fungal soil networks. Therefore, plant community stability is associated with the decoupling of prokaryote and fungal soil networks.

Conceptual framework reconciling the decoupling of prokaryote and fungal responses in buffering the propagation of local perturbation effects resulting in stable and unstable communities.
2/ Small genome size supports the naturalization of plants but constrains their invasive spread
By testing the effects of genome size and ploidy levels on plant naturalization and invasion, using ~11,000 species, we found that large genome constrains naturalization but favours invasion. A small genome is an advantage during naturalization, being linked to traits favouring adaptation to local conditions, but for invasive spread, traits associated with a large holoploid genome, where the impact of polyploidy may act, facilitate long-distance dispersal and competition with other species.

Small genome supports successful naturalization but constrains invasion where plants with large genome are most successful.
3/Hormonal imbalance is behind the advantageous but rare ability of root sprouting
Root sprouting is an advantageous but rare ability allowing clonal growth and regeneration after injury, even after fragmentation of the root system. This ability is typical of perennial weeds of arable land. In experiments with pairs of related plants differing in this ability, we confirmed the hypothesis that root sprouting species have a lower ratio of auxin to cytokinin than their relatives. However, most plants avoid this low ratio in order to avoid the risk of developmental deformations.

Evolution of the plant body in relation to drought
Natural selection by drought led plant vascular form to diversify in early evolution, as plants grew larger and spread on dry land. Network analysis of the conducting tissues of living, fossil, and idealised plants shows that drought acts to increase vascular complexity with plant size. This major reinterpretation of a key episode in plant evolution also answers the hundred-year-old question of their vascular complexity. It may find applications in breeding resistant crops.
