A large portion of the soil has been affected by over salinity and it has been known to limit the growth of many plants. Globally, the total area of saline soil was 397,000,000 ha and in continents like Africa, it makes up 2 percent of the soil.[34] The amount of soil salinization has reached 19.5% of the irrigated land and 2.1% of the dry-land agriculture around the world.[35] Soil salinization affects the plants using osmotic potential by net solute accumulation. The osmotic pressure in the plant is what maintains water uptake and cell turgor to help with stomatal function and other cellular mechanisms.[35] Over generations, many plant genes have adapted, allowing plants' phenotypes to change and built different mechanisms to counter salinity effects. The plant hormone ethylene is a combatant for salinity in most plants. Ethylene is known for regulating plant growth and development and adapted to stress conditions. Central membrane proteins in plants, such as ETO2, ERS1 and EIN2, are used for ...
