Abstract
Nitrogen is essential for plant growth, however excess nitrogen can have disastrous effects for plant root growth which can be accelerated by the emergence of global warming which increases the nitrogen concentrations in the soil. This can be observed by using the Arabidopsis thaliana plant, a common stand-in for agricultural plants. However, the use of the A. thaliana plant with specific mutated cax1-1 gene held an unknown underlying effect. An excess of nitrogen was added to see if it would have any negative effect on the growth phenotype of the plant, A. thaliana seedlings were kept constant regarding their light, temperature and soil intake. The effect of the nitrogen on the mutated and wild type plants was measured using root length at the end of a 6 week growth period. Root length showed no significant difference in the wild type vs. the mutant plants under nitrogen conditions. However, there was an increase in root growth in mutant plants under normal conditions.
