THE PRODUCTION OF GMO CROPS WITH IMPROVED NITROGEN EFFICIENCY. 2

The Production of GMO Crops with Improved Nitrogen Efficiency.

The Production of GMO Crops with Improved Nitrogen Efficiency.
The late 20th century and this century saw heightened levels of food production research. Specifically, the use of the scientific approach in food production has increased to a great dimension through the use of molecular approaches as well as the mineral fertilizers. The use of mineral fertilizers, nitrogenous, have seen significant disruptions of the natural ecosystems causing unsustainability in food production. This research sought to use metabolomics and transcriptomics to establish the key steps of nitrogen use in maize plant, genotype B73. The research surveyed the maize plant proteomics and metabolomics both at the vegetative stage and the mature leaf developmental stage under two growth conditions, namely low and high nitrogen supply. The level of genetic expression and that of metabolites in the surveyed plants would be indicative of the nitrogen use efficiency.
Outcomes.
Both the nitrogen starved and nitrogen supplied maize plants exhibited similar morphological characteristics both at the vegetative and the mature leaf stages, but the nitrogen starved plant was chlorotic. However, the kernel yield of nitrogen-starved and nitrogen supplied plants were different. The N- maize plant had a kernel yield of 15+/-4g whereas the N+ maize plant had a kernel yield of 252+/-17g, indicating a strong yield penalty as a result of variations in nitrogen concentrations. However, the variation in nitrogen concentration was shown to have limited effect on the plant’s phenotypic health both at the vegetative and mature leaf stages. In the end, the high concentration of soil nitrogen in along all the developmental stages of Zea mays, genotype B74, leads to the increased kernel yield because of the complementary accumulation of transcripts, metabolites and proteins.
