Late blight is a serious economic threat to potato crop, sometimes leading to complete crop loss. The resistance in potato to late blight can be qualitative or quantitative in nature. Qualitative resistance is not durable. Though quantitative resistance is durable, the breeding is challenging due to

A homologous series of N-(3-methylbutyl)amides of normal saturated C14, C15, C16, C17 and C18 fatty acids were identified as major components of glandular trichome extracts from Medicago sativa G98A, an alfalfa genotype resistant to the potato leafhopper, Empoasca fabae. A second homologous series

Four feruloyl amides, N-trans-feruloyloctopamine (1), N-cis-feruloyloctopamine (2), N-trans-feruloyltyramine (3), N-cis-feruloyltyramine (4), a cross-linked N-trans-feruloyltyramine dimer (5), and a cross-linked N-cis-feruloyltyramine dimer (6) were isolated from potato common scab lesions. The

Eleven compounds were isolated from potato peels and identified. Their structures were determined by interpretation of UV, MS, 1D, and 2D NMR spectral data and by comparison with reported data. The main components of the potato peels were found to be chlorogenic acid and other phenolic compounds,

BACKGROUND We are interested in the metabolic response to ingested macronutrients and the interaction between macronutrients in meals. Recently, we have determined the insulin and glucose response to ingestion of lard, olive oil, or safflower oil, fat sources varying in fatty acid composition and

The effects of beta-1,3-oligosaccharide elicitor on the metabolism of phenylpropanoids in potato tuber were analyzed quantitatively, by monitoring the time-dependent changes in the levels of seven compounds. The elicitor treatment caused an increase in the pool size of octopamine and tyramine amides

The carboxylate of Glu35 in the active site of potato epoxide hydrolase StEH1 interacts with the catalytic water molecule and is the first link in a chain of hydrogen bonds connecting the active site with bulk solvent. To probe its importance to catalysis, the carboxylate was replaced with an amide

Inhibition of human trypsin and chymotrypsin by proteinase inhibitors of plant origin was studied using the juice from the small intestine, without separation of the two enzymes, and synthetic amide substrates (BAPA, GLUPHEPA). The results were compared with the inhibition of the corresponding

The solution structure and backbone dynamics of the recombinant potato carboxypeptidase inhibitor (PCI) have been characterized by NMR spectroscopy. The structure, determined on the basis of 497 NOE-derived distance constraints, is much better defined than the one reported in a previous NMR study,

Macroporous semi-interpenetrating polymer networks (semi-IPN) composite hydrogels were synthesized by cross-linking polymerization of acrylamide (AAm) with N,N'-methylenebisacrylamide (BAAm) in the presence of potato starch (PS) or an anionic polyelectrolyte derived from PS (PA), below the freezing

BACKGROUND Potatoes contain a diverse range of phytochemicals which have been suggested to have health benefits. Metabolite profiling and quantification were conducted on plant extracts made from a white potato cultivar and 'Urenika', a purple potato cultivar traditionally consumed by New Zealand
