Abstract Local adaptation in plants often requires coordinated shifts among resources. Lowry et al. provide evidence for physiological and genomic mechanisms underpinning adaptive shifts in yellow monkeyflower ( Mimulus guttatus) , such as the transition between annual and perennial life histories. In M. guttatus , differential activity of gibberellins, governed partially by a chromosomal inversion, is responsible for shifts between growth, reproduction, and herbivore defense (secondary compound production).
