Integrated regulation triggered by a cryophyte ω-3 desaturase gene confers multiple-stress tolerance in tobacco


Salt stress: 

It is expected to cultivate foods with strong salt tolerance through biotechnology. It not only can increase grain output in salinized areas, but it can also expand the available area of planting grains in salinized areas. More saline-alkali land can be used to ultimately increase grain output.


Drought and cold stress: 

The ability of plants to resist drought and cold stress can be effectively enhanced by biotechnology, and the loss of food caused by natural disasters can be reduced. At the same time, the area of cultivation of tropical and subtropical crops and large-scale water-demand crops will be expanded.


It is thought that omega-3 fatty acid desaturases (FADs) have some effect on a plants ability to tolerate stress. This study digs deeper into this relationship.
