Coronatine, a virulence factor of plant bacteria, facilitates bacterial infection through an ER (endoplasmic reticulum)-mediated mechanism and works by affecting the ethylene signaling pathway.

Freezing Treatment

Abstract Potato (Solanum tuberosum L.) is the fourth largest food crop in the world. Low temperature causes serious damage to potato plants every year, and freezing tolerance has become a hot spot in potato research. Galactinol synthase (GolS) is a key enzyme in the synthesis of raffinose family oligosaccharides (RFOs), and plays an important role in the response of plants to abiotic stress. In this study, the ScGolS1 gene from S. commersonii was cloned and introduced into the S. tuberosum cultivars ‘Atlantic’ and ‘Desiree’ via Agrobacterium-mediated transformation. Phenotyping assay showed that overexpression of the ScGolS1 could significantly improve freezing tolerance in transgenic potato plants. Further physiological and biochemical results showed that the relative conductivity, malondialdehyde (MDA) content, and 3,3'-Diaminobenzidine (DAB) staining of the transgenic lines decreased, and the plant survival rate increased compared with wild type (WT). Moreover, CBF1, CBF2, CBF3, CBF downstream cold responsive genes COR413, COR47 and ERF transcription factor genes ERF3, ERF4, ERF6 in the ethylene signaling pathway were all induced by freezing treatment, while higher levels were observed in ScGolS1 overexpression lines compared with WT. In addition, other genes such as MIPS, STS and RS genes from RFO metabolic pathway and some sugars content were altered in response to freezing treatment. This indicates that overexpression of the ScGolS1 gene induced both the regulation of the ethylene signaling pathway and the metabolism of raffinose series oligosaccharides, regulating the balance of sugar composition and improved anti-peroxidation capacity, and thereby improved freezing tolerance in potato. These results provide theoretical support and genetic resources for freezing tolerance breeding in potato.
