1
Characterization of sugar-response Arabidopsis (Arabidopsis thaliana) mutants to engineer plants for higher ethanol, soydiesel and soy protein production By Xin Li
2
To find sugar-regulating genes that direct the flow of sugar to harvested portions of the plant. Purposes
3
To find sugar-regulating genes that direct the flow of sugar to harvested portions of the plant. To produce cheaper soydiesel, more soy protein, and less expensive ethanol from the soybean plants. Purposes

Results
31
Conclusion I found a mutant that is hypersensitive to 6% glucose and 6% sucrose.
32
Conclusion I found a mutant that is hypersensitive to 6% glucose and 6% sucrose. The mutant’s genotype is SALK_113292.
33
Conclusion I found a mutant that is hypersensitive to 6% glucose and 6% sucrose. The mutant’s genotype is SALK_113292. The disabled gene in mutant SALK_113292 is at1g06230.
34
Conclusion I found a mutant that is hypersensitive to 6% glucose and 6% sucrose. The mutant’s genotype is SALK_113292. The disabled gene in mutant SALK_113292 is at1g06230. The gene contains a bromodomain protein
35
Future Work Grow SALK_113292 in 1% glucose and 1% sucrose
36
Future Work Grow SALK_113292 in 1% glucose and 1% sucrose Grow SALK_113292 in 1% sorbitol and 6% sorbitol
