The recent discovery of an endogenous hormonal activity for strigolactones in shoot branching was surprising since these molecules were thought to mostly play roles as signaling molecules between organisms. Even in the context of plant hormones, strigolactones appear to be different in that their role in plant development is quite restricted. This most probably reflects early days and new hormonal functions will most probably be found for these compounds in the future. In this respect, the exogenous role of strigolactones in parasitic plant seed germination may hint to functions of this compound in seed development. However, showing new roles for strigolactones in the seed or any other aspect of plant development for that matter will require developing assays in model genetic systems such as Arabidopsis and rice where we can take full advantage of the experimental tools that are available.
