<p style="color:#1b1b1b;">In order to further increase the plant ability of formaldehyde uptake and metabolism by synthesis biology technology, we choosed four enzyme-coding genes related to formaldehyde metabolic pathways from microorganism and plant: 3-hexulose-6-phosphate (HPS), 6-phospho-3-hexuloisomerase (PHI), formaldehyde dehydrogenase (FALDH) and formate-dehydrogenase (FDH). These genes are transformed into plants and will promote formaldehyde metabolism. For security reasons, we also induce <i>AdCP</i> gene into our plans because of its capability to lead to pollen abortion. At the same time, chloroplast transformation is taken into consideration to avoid gene flow and improve gene expression.

The ribulose monophosphate (RuMP) pathway is one of the formaldehyde-fixation pathways found in microorganisms called methylotrophs, which utilize one-carbon compounds as the sole carbon source. The key enzymes of this pathway are 3-hexulose-6-phosphate synthase (HPS), which fixes formaldehyde to D-ribulose-5-phosphate (Ru5P) to produce D-arabino-3-hexulose-6-phosphate (Hu6P), and 6-phospho-3-hexuloisomerase (PHI), which converts Hu6P to fructose 6-phosphate (F6P). The two key enzymes work in chloroplast both. We will use fusion expression to conduct heterologous expression in tobacco (<i>Chen et al., 2010</i>).
