Probing flowers' genetic past

Article Abstract:

A double-duty gene that was hypothesized as the evolutionary beginning of angiosperms has been found in the weed Arabidopsis thaliana. Animesh Ray found that the gene SIN1 controls the development of ovules and triggers flower growth at the appropriate time.

Article Abstract:

A key protein-pair match important to developing embryos has been discovered. The receptor for the protein Sonic Hedgehog (Shh) has been found to be the membrane-bound protein Patched, rather than one called Smoothened.
