Abstract
In order to investigate whether SfPR1a, a pathogenesis-related protein gene from an annual halophytic species Salsola ferganica Drob., was involved in the response to plant defense, qRT-PCR was employed to detect its expression patterns under abscisic acid (ABA), jasmonic acid (JAs), ethylene synthesis direct precursor (ACC), and NaCl treatments. We also identified resistances to salt, drought and Pseudomonas syringae tomato (PstDC3000) of transgenic tobacco were identified. The expression of SfPR1a gene in roots was significantly higher than that in shoots, and positively induced by ABA, JAs, ACC, and NaCl treatments. The malondialdehyde (MDA) content of transgenic tobacco was significantly lower than that of wild-type tobacco, showing a strong resistance to drought. The ectopic expression of SfPR1a gene improved plant growth under salt stress. After infection of P. syringae, transgenic tobacco leaves showed serious necrosis reaction, but the overall resistance phenotype of the plants was significantly better than that of WT. Subcellular localization analysis showed SfPR1a was localized in the plant cell apoplastic space. The above results indicated that the SfPR1a gene is involved in plant resistance to abiotic and biotic stresses.
