Folate deficiency is a leading cause of birth defects and is implicated in several other diseases. We are interested in how much folate concentrations vary among potato germplasm. We determined total folate concentrations of potato tubers from 67 cultivars, advanced breeding lines, or wild species.
An ultrahigh-performance liquid chromatography-tandem mass spectrometry method was developed and validated for the profiling of six folate species in potatoes. The calibration curves cover a wide, linear range (the lower and upper limits of quantitation range between 0.22-0.24 and 216.07-242.28
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
Folates are important cofactors in one-carbon metabolism in all living organisms. Since only plants and micro- organisms are capable of biosynthesizing folates, humans depend entirely on their diet as a folate source. Given the low folate content of several staple crop products, folate deficiency
Insufficient dietary intake of micronutrients, known as "hidden hunger", is a devastating global burden, affecting two billion people. Deficiency of folates (vitamin B9), which are known to play a central role in C1 metabolism, causes birth defects in at least a quarter million people annually.
Carotenoids and folate are two mandatory supplying micronutrients for children or pregnant women. Inadequate intake of these two nutrients was relevant to a higher mortality of both children and pregnancies. This study is intended to investigate the thermal impact on the changes of carotenoids and
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
Changes in the metabolite composition of potato
tubers during low-temperature storage can affect their nutritional value, susceptibility to bruising, and processing qualities. Here, we measured changes in the amounts of folate

Malnutrition is one of the world's largest health concerns. Folate (also known as 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
The subcellular distributions of folate and folate-synthesizing enzymes were investigated in pea leaves. It was observed that the mitochondrial folate pool (approximately 400 micron) represented approximately 50% of the total pool. Furthermore, all the enzymes involved in tetrahydrofolate
Adequate intake of folate reduced the risk of abnormalities in early embryonic brain development such as the risk of malformations of the embryonic brain/spinal cord, collectively referred to as neural tube defects (NTDs). Folate is extremely sensitive to destruction by heat, oxidation and UV light.
As part of an effort to improve the safety of plant foods, a need exists to more clearly delineate the mechanisms of toxicities of glycoalkaloids, which may be present in Solanum plant species such as potatoes, tomatoes and eggplants. Alpha-chaconine is a major glycoalkaloid present in potatoes. To
A structural equation model (SEM) was used to test multiple and simultaneous relationships between socio-demographic factors, dietary patterns, biochemical levels of folate, vitamin B12, docosahexaenoic acid (DHA), and its effects on homocysteine (Hcy)
Folate intake is strongly influenced by various methods of cooking that can degrade the natural forms of the vitamin in foods. The aim of the present study was to determine the effect of different cooking methods on folate retention in various foods that contribute to folate intake in the UK diet.
Cinnamic acid-4-hydroxylase activation factor has been found to be located in the supernatant fraction of wounded potato tissue homogenate in phosphate buffer. The factor has been purified to homogeneity as judged by SDS polyacrylamide gel electrophoresis, by heat treatment on boiling water-bath for
