Photo of the experimental setup used to evaluate the comparative response to herbivory across the Brachypodium species complex. The picture was taken during the feeding experiment, in which the authors placed one locust on multiple lines of diploid Brachypodium distachyon, B. stacei, and B. hybridum allopolyploid. Locusts were allowed to feed for 48 h, after which damage and fitness were evaluated.

Front, side, and dissected view photographs of anthesis flowers from Nicotiana section Repandae allopolyploids (N. nudicaulis, N. repanda, and N. stocktonii) and their diploid progenitors N. sylvestris and N. obtusifolia. Nicotiana nudicaulis also has side view flower bud photographs at Stage 1, Stage 2, and Stage 3, which represent 60%, 85%, and 95% of anthesis length, respectively. Nicotiana nudicaulis and N. repanda have transgressive delphinidin pigmentation not found in either progenitor.

Moreover, we find that polyploid species have more loci under positive selection, particularly in genes relating to chemical defence against herbivores, a key ecological pressure on tropical trees 🐛

These discoveries highlight that Piezo-based mechanochemical signaling operates not as a simple ON/OFF switch, but rather as a rheostat, or dimmer switch. The regulatory logic behind this mode of Piezo action is an exciting direction for future research!
