A.thaliana roots interacting with Hieracium


ABSTRACT: Plant roots perceive neighbouring roots even when resource depletion is low. The transcriptomic response to the presence or absence of an inferior competitor (Hieracium pilosella) is therefore examined in roots of A. thaliana. The experiment was set up in pots filled with non-sterile sand, that allowed to sample roots of eight week old Arabidopsis plants. 3 biological replicates per treatment were examined. Each of these replicates represents 3 pooled samples from individual plants.

Root-root interactions are much more sophisticated than previously thought, yet the mechanisms of belowground neighbor perception remain largely obscure. Genome-wide transcriptome analyses allow detailed insight into plant reactions to environmental cues. A root interaction trial was set up to explore both morphological and whole genome transcriptional responses in roots of Arabidopsis thaliana in the presence or absence of an inferior competitor, Hieracium pilosella. Neighbor perception was ind  ...[more]
