Conclusion
This study concluded that overexpression of CsGGCT2;1 in Camelina
increased AsIII tolerance. Compared to WT, CsGGTC2;1 OE lines had
significantly higher biomass, lower arsenic accumulation, better
chlorophyll content, and lower MDA and ROS levels. The CsGGCT2;1OE lines had slightly higher levels of 5-OP and increased levels of theCsOXP1 gene, indicating a role of GGCT2;1 in increasing
the rate of GSH recycling and enhancing survival under AsIII stress via
improved GSH homeostasis. This research demonstrates the successful
translation and applications of findings from the model plant
Arabidopsis to Camelina, a dedicated biofuel crop. These results
highlight the potential of modified plants to thrive under AsIII stress
with reduced accumulation, thus enabling the cultivation of crops on
contaminated marginal lands to ensure food safety and future food
security.
