| Phenotype Detail | Nodules formed on transgenic roots carrying the RNAi-intron1 silencing cassette are nitrogen fixing, with a normal differentiated structure and an active and persistent meristem. Nevertheless, due to the small size of these RNAi-intron1 nodules compared with control nodules, it is clear that growth has been significantly modified. Importantly, MtHAP2-1 transcript and protein levels in these nodules, 21 d after inoculation, were significantly higher than for wild-type. |
