Plants adapting to harsh environments

http://www.sciencedaily.com/releases/2011/01/110131161344.htm



Scientists have recently discovered that the the plant, Arabidopsis thaliana has the ability yo live in different conditions to be able to survive in it's habitat. Scientists tested out their theory by planting some 300 plants in different parts of Europe, one beaches and on land. On the beach was an area of high saline soil(or salt) and on land, areas with no salt in the soil, also having low sodium. Scientist found that that plants that were in the areas of high sodium had a form of gene, HTK1 which regulates sodium intake and then distributes it along the plant, without this gene the plant would die. Scientist are able to see how these plants have been able to adapt to their environment and be able to live in harsh conditions and are searching for ways to find technology that they can apply to other plants so they can survive in different areas also.




Opinion




I think that it is very good that scientist have been able to notice that the same kind of plant can live in places where, regular plant die and at the same time, it can live in normal conditions. It seems amazing how these plants have been able to change so that they can survive. Hopefully, scientist will now try to develop a technology that they can apply to other plant so that they can also survive in harsh conditions. In places of drought and famine due to little rain, scientists can be able to adapt characteristics from desert plants to plants that people can live off like corn and wheat for example. That way we will adapt to our surroundings and we'll be able to survive in harsh conditions.
