Expression Levels of the γ-Glutamyl Hydrolase I Gene Predict Vitamin B9 Content in Potato Tubers

Creator:: Goyer, Aymeric
Abstract:: Biofortification of folates in staple crops is an important strategy to help eradicate human folate deficiencies. Folate biofortification using genetic engineering has shown great success in rice grain, tomato fruit, lettuce, and potato tuber. However, consumers’ skepticism, juridical hurdles, and lack of economic model have prevented the widespread adoption of...

Thiamine in plants: Aspects of its metabolism and functions

Creator:: Goyer, Aymeric
Abstract:: Thiamine diphosphate (vitamin B1) plays a fundamental role as an enzymatic cofactor in universal metabolic pathways including glycolysis, the pentose phosphate pathway, and the tricarboxylic acid cycle. In addition, thiamine diphosphate has recently been shown to have functions other than as a cofactor in response to abiotic and biotic stress...

Vitamin B1 content in potato: effect of genotype, tuber enlargement, and storage, and estimation of stability and broad-sense heritability

Creator:: Goyer, Aymeric and Haynes, Kathleen G.
Abstract:: Thiamine pyrophosphate (vitamin B1) is an essential nutrient in the human diet, and is often referred as the energy vitamin. Potato contains modest amounts of thiamine. However, the genetic variation of thiamine concentrations in potato has never been investigated. In this study, we determined thiamine concentrations in freshly-harvested unpeeled tubers...

Genetic diversity of thiamine and folate in primitive cultivated and wild potato (Solanum) species

Creator:: Goyer, Aymeric and Sweek, Kortney
Abstract:: Biofortification of staple crops like potato via breeding is an attractive strategy to reduce human micronutrient deficiencies. A prerequisite is metabolic phenotyping of genetically diverse material which can potentially be used as parents in breeding programs. Thus, the natural genetic diversity of thiamine and folate contents was investigated in indigenous...

Exploring vitamin B9 diversity in wild and primitive potatoes for modern crop improvement

Creator:: Robinson, Bruce R., Sathuvalli, Vidyasagar, Bamberg, John, and Goyer, Aymeric
Abstract:: Malnutrition is one of the world’s largest health concerns. Folate (a.k.a. vitamin B9) is essential in the human diet and without adequate folate intake several serious health concerns such as congenital birth defects and an increased risk of stroke and heart disease can occur. Most people’s folate intake remains sub-optimal...

RNA-Seq analysis of early infected potato leaves by potato virus Y in resistant and susceptible potato varieties

Creator:: Goyer, Aymeric, Hamlin, Launa, Crosslin, James M., Buchanan, Alex, and Chang, Jeff H.
Abstract:: Background Potato Virus Y (PVY) is one of the most important plant viruses affecting potato production. The interactions between potato and PVY are complex and the outcome of the interactions depends on the potato genotype, the PVY strain, and the environmental conditions. A potato cultivar can induce resistance to a...

Enhancement of thiamin in plants by metabolic engineering

Creator:: Dong, Wei, Stockwell, Virginia O., and Goyer, Aymeric
Abstract:: Thiamin is an essential nutrient in the human diet. Severe thiamin deficiency leads to beriberi, a lethal disease which is common in developing countries. Thiamin biofortification of staple food crops is a possible strategy to alleviate thiamin deficiency-related diseases. In plants, thiamin plays a role in the response to abiotic...

Overexpression of thiamin biosynthesis genes increase leaf and seed thiamin content but not resistance to Xanthomonas oryzae in rice

Creator:: Dong, Wei, Thomas, Nicholas, Ronald, Pamela C., and Goyer, Aymeric
Abstract:: Thiamin diphosphate (ThDP), also known as vitamin B1, serves as an enzymatic cofactor in glucose metabolism, the Krebs cycle, and branched-chain amino acid biosynthesis in all living organisms. Unlike plants and microorganisms, humans are not able to synthesize ThDP de novo and must obtain it from their diet. Staple crops...

Thiamin biofortification of crops

Creator:: Goyer, Aymeric
Abstract:: Thiamin is essential for human health. While plants are the ultimate source of thiamin in most human diets, staple foods like white rice have low thiamin content. Therefore, populations whose diets are mainly based on low-thiamin staple crops suffer from thiamin deficiency. Biofortification of rice grain by engineering the thiamin...

Priming potato with thiamin to control potato virus Y

Creator:: Vinchesi, Amber C., Rondon, Silvia I., and Goyer, Aymeric
Abstract:: Potato virus Y (PVY) is a major potato pathogen affecting potato yields worldwide. Thiamin, a water-soluble B vitamin (vitamin B1) has been shown to boost the plant’s immunity, thereby increasing resistance against pathogens. In this study, we tested different concentrations of thiamin (1 mM, 10 mM, 50 mM, 100 mM)...

Single nucleotide polymorphism (SNP) markers associated with high folate content in wild potato species

Creator:: Bali, Sapinder, Robinson, Bruce R., Sathuvalli, Vidyasagar, Bamberg, John, and Goyer, Aymeric
Abstract:: Micronutrient deficiency, also known as the hidden hunger, affects over two billion people worldwide. Potato is the third most consumed food crops in the world, and is therefore a fundamental element of food security for millions of people. Increasing the amount of micronutrients in food crop could help alleviate worldwide...
