✦ Synopsis

The response to iron deficiency was investigated in 16 ecotypes ofArabidopsis thaliana (L.) Heynh. and in Arabidopsis ,qr(ffithiana. An increase in root ferric reductase activity was observed under conditions of iron deficiency in these ecotypes and in both species. This observation is consistent with a Strategy I response which is typical for dicot plants. A. griffithiana, however, showed a lower induction of ferric reductase activity in response to iron deficiency than that of the commonly studied A. thaliana Columbia ecotypes.
