Article Synopsis
- - Sporobolus virginicus is a salt-tolerant grass found globally, with a specific Japanese variant capable of thriving in salt conditions three times saltier than seawater.
- - Researchers generated 3500 transgenic Arabidopsis lines using cDNA from S. virginicus and identified 10 lines with improved salt tolerance, including those containing glycine-rich RNA-binding proteins (SvGRP1 and SvGRP2).
- - Analysis of these transgenic plants showed that SvGRP1 enhances salt tolerance by altering specific metabolic pathways and increasing certain acid levels, shedding light on the potential role of GRPs in helping plants survive salinity stress.
Understanding the mechanisms used by halophytic members of the Poaceae to cope with salt stress will contribute to the knowledge necessary to genetically engineer salt-tolerant crops. In this study, we identified a genotype of Sporobolus virginicus, a halophytic turf grass collected in Japan, and investigated its growth rate, ion concentration and secretion, and proline concentration in comparison with the reported properties of genotypes collected from the USA, South Africa and Egypt. Surprisingly, the Japanese genotype showed a salinity tolerance up to 1.
