The Endogenous Brassinosteroid Content and Balance in Potato Microclones Is Determined by Organ Specificity and the Variety Ripening Term.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The brassinosteroid (BS) profiles in shoots and roots of the potato plants were shown to be organ-specific and dependent on the term of variety ripening. The amount of all studied groups of steroid phytohormones proved to be an order of magnitude higher in roots than in shoots. In roots, the

Synthesis of the aggregation pheromone of the Colorado potato beetle from its degradation product.

Ingia / Ingia

Incubation of the Colorado potato beetle aggregation pheromone, (S)-1,3-dihydroxy-3,7-dimethyl-6-octen-2-one, with antennal or leg extracts from this beetle gave 6-methyl-5-hepten-2-one as the major product. This ketone was used as a substrate in a stereoselective synthesis of the pheromone. It was

The effect of temperature and duration of exposure of potato tuber moth (Lepidoptera: Gelechiidae) in infested tubers to the biofumigant fungus Muscodor albus.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The endophytic fungus, Muscodor albus produces several volatile compounds (alcohols, esters, ketones, acids and lipids) that are biocidal for a range of organisms including plant pathogenic bacteria and fungi, nematodes and insects. We studied the effects of these volatiles on 3-day-old potato tuber

Attacks by a piercing-sucking insect (Myzus persicae Sultzer) or a chewing insect (Leptinotarsa decemlineata Say) on potato plants (Solanum tuberosum L.) induce differential changes in volatile compound release and oxylipin synthesis.

Ingia / Ingia

Plant defensive strategies bring into play blends of compounds dependent on the type of attacker and coming from different synthesis pathways. Interest in the field is mainly focused on volatile organic compounds (VOCs) and jasmonic acid (JA). By contrast, little is known about the oxidized

Me2(CH2Cl)SiCN: Bifunctional Cyanating Reagent for the Synthesis of Tertiary Alcohols with a Chloromethyl Ketone Moiety via Ketone Cyanosilylation.

Ingia / Ingia

We report a novel bifunctional cyanating reagent, Me2(CH2Cl)SiCN, which paves the way to a one-pot sequential synthesis of tertiary alcohols featuring a chloromethyl ketone moiety via enantioselective ketone cyanosilylation. This method contributes to gram-scale enantioselective total synthesis of

Proteinase activity in potato plants.

Ingia / Ingia

Several vegetative tissues of potato plants were screened for proteinase activity. Both endopeptidase and exopeptidase activities were investigated using gelatin and L-amino acid-4-nitroanilides (benzoyl-L-arginine-4-nitroanilide/BAPA, glutaryl-L-phenyl-alanine-4-nitroanilide/GLUPHEPA,

Toxicity and metabolism of exogenous α,β-unsaturated carbonyls in potato (Solanum tuberosum L.) tubers.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

A group of aliphatic α,β-unsaturated carbonyl compounds was evaluated for their utility as inhibitors of sprout growth in stored potato tubers (Solanum tuberosum L.). Nondormant tubers were treated with vapors of six 8-10-carbon compounds of this chemistry. Subsequent sprout growth at 16 °C (95%

Asymmetric reduction of prochiral ketones to chiral alcohols catalyzed by plants tissue.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

As an important organic compound, chiral alcohols are the key chiral building blocks to many single enantiomer pharmaceuticals. Asymmetric reduction of the corresponding prochiral ketones to produce the chiral alcohols by biocatalysis is one of the most promising routes. Asymmetric reduction of

Cuticular waxes from potato (Solanum tuberosum) leaves.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The qualitative and quantitative compositions of leaf cuticular waxes from potato (Solanum tuberosum) varieties were studied. The principal components of the waxes were very long chain n-alkanes, 2-methylalkanes and 3-methylalkanes (3.1-4.6 microg cm(-2)), primary alcohols (0.3-0.7 microg cm(-2)),

Alternative synthesis of the Colorado potato beetle pheromone.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

A concise preparation of the pheromone secreted by the male Colorado potato beetle [viz. (3S)-1,3-dihydroxy-3,7-dimethyl-6-octen-2-one] was accomplished in four steps starting from 2-fluoronerol or 2-fluorogeraniol. The key step in the synthesis involves a 6-endo epoxide ring-opening with ester

β-Thujone and Its Derivatives Modify the Probing Behavior of the Peach Potato Aphid.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Thujone is a natural biologically active monoterpene ketone component of essential oils of numerous plants. The aim of the study was to evaluate the effect of β-thujone and β-thujone derivatives bisulfite adduct, lactone, oxime, and lactam application on behavior of Myzus persicae (Sulz.)

Analysis of volatile flavor compounds of sardine (Sardinops melanostica) by solid phase microextraction.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Generally the main component of fishy flavor is considered to be trimethylamine. On the other hand, carbonyl compounds, produced from oxidation of polyunsaturated fatty acid by lipoxygenase or by autoxidation, might have some contribution to the fishy flavor. Since sardine skin contains high levels

Effect of in ovo feeding of dextrin-iodinated casein in broilers: II. Hatch window and growth performance.

Ingia / Ingia

Studies were conducted using a commercial InovojectTM system to determine effects of in ovo feeding of dextrin and iodinated casein (IC) on hatch and posthatch growth in broilers. At ∼18.5 d embryonic development, eggs were treated with 0, 240, or 480 μg IC/mL in saline (Cont, IC240, and IC480) or

Role of extracellular signal-regulated kinase and PKC alpha in cytosolic PLA2 activation by bradykinin in MDCK-D1 cells.

Ingia / Ingia

The actions of bradykinin (BK) in Madin-Darby canine kidney (MDCK) and other cell types involve formation of arachidonic acid (AA) and AA products by as-yet-undefined mechanisms. We found that BK promoted AA release and an increase in phospholipase A2 (PLA2) activity in subsequently prepared MDCK-D1

Ingia / Ingia

Previous studies have established that whey protein manufacture unit operations influence the flavor of dried whey proteins. Additionally, manufacturers generally instantize whey protein isolate (WPI; ≥ 90% protein) by agglomeration with lecithin to increase solubility and wettability. Whey protein
