|a Glutamyl-tRNA reductase1 (HEMA1) and ferrochelatase1 (FC1) are both expressed in response to salt stress in the biosynthetic pathway of tetrapyrroles. Peanut (Arachis hypogaea L.) HEMA1 and FC1 were isolated by RT-PCR. The amino acid sequence encoded by the two genes showed high similarity with that in other plant species. The AhFC1 fusion protein was verified to function in chloroplast using Arabidopsis mesophyll protoplast. Sense and wild-type (WT) tobaccos were used to further study the physiological effects of AhHEMA1 and AhFC1. Compared with WT, the Heme contents and germination rate were higher in AhFC1 overexpressing plants under salt stress. Meanwhile, overexpressing AhHEMA1 also led to higher ALA and chlorophyll contents and multiple physiological changes under salt stress, such as higher activities of superoxide dismutase (SOD) and ascorbate peroxidase (APX), lower contents of reactive oxygen species (ROS) and slighter membrane damage. In addition, the activities of CAT, POD and APX in the AhFC1 overexpressing plants were significantly higher than that in WT lines under salt stress, but the activity of SOD between the WT plants and the transgenic plants did not exhibit significant differences. These results suggested that, peanut can enhance resistance to salt stress by improving the biosynthesis of tetrapyrrole biosynthetic
