It opens many questions on the phenotypic effects mediating the preferential predation, and on the co-evolution between durum wheat and Messor ants!

The originality of this work is that preferential predation of specific wheat genotypes was shown in real plant stands, directly in the field, i.e., not by making ants chose between different seeds in lab settings.

He could confirm the effect of the locus based on a cafeteria experiment

Quite interestingly, he could explain a large proportion of this preferential attacks by allelic variation at a specific genomic region on chr. 2A, containing a 3.6 Mb chromosomal inversion

Clément noticed that specific durum wheat genotypes got attacked by Messor barbarus ants in the field

Among many symposia, I'll be co-animating one on genetic models accounting for intra-specific interactions, covering trees, plants, animals, with Piter Bijma (WUR) as an invited.

The PhD student will work on root branching phenotyping, QTL validation, and varietal mixture experiments to decipher the link between root branching, resource availability, and plant-plant interactions

Our group has identified several Quantitative Trait Loci (QTLs) associated with root branching in durum wheat . Our preliminary data indicate that these QTLs associate with varietal mixture performance under contrasted environmental conditions

and thus they disengage from the arms race for root proliferation and biomass accumulation. Very interesting to see such belowground plasticity in response to plant neighbours, and to identify this plasticity as a target trait for plant breeding and mixture assembly!

This is because highly competitive varieties tend to over-produce roots in monoculture because they have a highly competitive neighbour (i.e., themselves). In mixture, such highly competitive varieties benefit from having, on average, weaker competitors,
