The C-1' epimers of the sesquiterpenoids 2-(1',2'-dihydroxy-1'-methylethyl)-6,10-dimethylspiro[4,5]dec-6,9-dien-8-one and 2-(1',2'-dihydroxy-1'-methylethyl)-6,10-dimethyl-9-hydroxyspiro[4,5]dec-6-en-8-one were isolated from potato tubers infected with Phoma foveata and Fusarium spp., in addition to

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

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

L-Tyrosine beta-naphthylamide, a synthetic substrate designed to measure tyrosine aminopeptidase activity, is a potent inhibitor of hydroxycinnamoyl-CoA:tyramine N-(hydroxycinnamoyl)transferase (THT) purified from elicited tobacco cell-suspension cultures. The inhibition is competitive, with the

A pathogen elicitor-inducible soluble acyltransferase (tyramine hydroxycinnamoyltransferase [THT], EC 2.3.1), which catalyzes the transfer of hydroxycinnamic acids from hydroxycinnamoyl-coenzyme A (CoA) esters to tyramine in the formation of N-hydroxycinnamoyltyramine, was partially purified with a

Resistance to late blight in potato is either qualitative or quantitative in nature. The quantitative resistance is durable, but the molecular and biochemical mechanisms underlying quantitative resistance are poorly understood, and are not efficiently utilised in potato breeding. A non-targeted

A better understanding of defence responses elicited during compatible plant-virus interactions is a current goal in plant pathology. We analysed defence responses during infection of Solanum tuberosum L. cv. Desiree with Potato virus X (PVX) at the transcript and metabolite level. A mostly

As part of the response to pathogen infection, potato plants accumulate soluble and cell wall-bound phenolics such as hydroxycinnamic acid tyramine amides. Since incorporation of these compounds into the cell wall leads to a fortified barrier against pathogens, raising the amounts of hydroxycinnamic

In human and animal cells, the catecholamines are involved in glycogen mobilization. Since the compounds are found in a potato, their function in starch mobilization was hypothesized. In order to verify this hypothesis, the transgenic potato plants Solanum tuberosum L. cv. Desiree overexpressing

Quantitative resistance is polygenically controlled and durable, but the underlying molecular and biochemical mechanisms are poorly understood. Secondary cell wall thickening is a critical process in quantitative resistance, regulated by transcriptional networks. This paper provides compelling

Hydroxycinnamoyl-CoA:tyramine N-(hydroxycinnamoyl)transferase (THT; EC 2.3.1.110) catalyzes the transfer of hydroxycinnamic acids from the respective CoA esters to tyramine and other amines in the formation of N-(hydroxycinnamoyl)amines. Expression of THT is induced by Phytophthora infestans, the

Harvesting microalgae presents a challenge in selecting the most economical method for low cost algal bioproducts. Previous studies have shown coagulation-flocculation to be the most efficient method for large scale microalgae harvesting. This study focused on modifying native potato starch with

BACKGROUND In six double-blind studies involving 182 tests of dietary migraine patients sensitive to tyramine and beta-phenylethylamine, 18% reported headaches from placebos which were all concealed in gelatin capsules. OBJECTIVE The purpose of this research was to test a hypothesis: gelatin is

Hydroxycinnamoyl-CoA : tyramine N-(hydroxycinnamoyl) transferase (THT) is a pivotal enzyme in the synthesis of N-(hydroxycinnamoyl)-amines, which are associated with cell wall fortification in plants. The cDNA encoding THT was cloned from the leaves of UV-C treated Capsicum annuum (hot pepper) using

The study aimed at determining the effect of protein type and indigestible carbohydrates on the concentration of microbial metabolites in the large intestine of pigs. The experiment involved 36 pigs (15 kg initial body weight) divided into six groups, fed cereal-based diets with highly digestible
