The idea of developmental buffering is key to understanding the environmental impact on evolutionary change. Studies using laboratory model organisms have proposed several hypotheses on the molecular basis of developmental buffering. However, it is still largely unknown how the level of buffering is controlled, and whether developmental genes can be affected by environmental stress in natural populations. I have established a model to test these questions using the ascidian Ciona intestinalis species complex. In the first part of my talk, I will show my recent discovery that ER chaperones might comprise a cellular basis of developmental buffering. In the latter part of my talk, I will show how developmental genes could be affected by environmental stress, and discuss how the idea of developmental buffering might link to the evolutionary process.
