Expression of Rice Galactinol Synthase Gene in Maize
August 14, 2019
Galactinol synthase (GolS) is an important enzyme that hastens the production of raffinose oligosaccharides (RFOs) which have vital functions in abiotic stress adaptation of plants, particularly drought tolerance. Researchers have isolated the GolS gene in several plants to develop material resources for generating transgenic plants resistant to adverse environmental factors.
In a previous research by Agricultural Genetics Institute and partners, the researchers have isolated a GolS gene from the DNA of rice (named OsGolS). In their latest study, the isolated OsGolS gene was introduced to maize using Agrobacterium tumefaciens-mediated transformation. Tests results indicated that the transgene was successfully integrated in the genome of the regenerated maize plants. Further analysis showed that the OsGolS was transcribed into mRNA in maize and was highly expressed.
These results provide a basis for the study of the function of OsGolS in drought responses and for the development of drought stress tolerant crops.
