ABSTRACT: Dry legumes are staple and potentially functional food, being a good source of polyphenols, flavonoids, antioxidant activity. The objective this study was to determine the total polyphenol content (TPC), flavonoid (TFC), their relation with capacity in 17 chickpea lines having colored seed coats (black, red, brown, green, rubiginous, gray, yellow, cream, or beige). coat usually contains more than 95% these compounds. In study, both TPC TFC varied significantly among different were...
In contrast to the detailed molecular knowledge available on anthocyanin synthesis, little is known about its catabolism in plants. Litchi (Litchi chinensis) fruit lose their attractive red color soon after harvest. The mechanism leading quick degradation of anthocyanins pericarp not well understood. An enzyme (ADE) was purified homogeneity by sequential column chromatography, using partially from litchi as a substrate. ADE, 116 kD urea SDS-PAGE, identified laccase (ADE/LAC). full-length...
In contrast to detailed knowledge regarding the biosynthesis of anthocyanins, largest group plant pigments, little is known about their in planta degradation. It has been suggested that anthocyanin degradation enzymatically controlled and induced when beneficial plant. Here we investigated enzymatic process Brunfelsia calycina flowers, as they changed color from purple white. We characterized by which B. protein extracts degrade anthocyanins. A candidate peroxidase was partially purified its...
SummaryMany green decorative branches ("greens"), which form an important part of ornamental bouquets, originatefrom shade plants, and are commercially grown in Israel under black nets. We studying the possibility to manipulate nature vegetative growth greens improve yield quality desirable for various crops.The present paper summarizes results obtained Pittosporum variegatum nets optical properties: green, red, blue, grey, black, reflective. The knitting density design were adjusted give...
Temperature is one of the main external factors affecting anthocyanin accumulation in plant tissues: low temperatures cause an increase and elevated a decrease concentration. Several metals have been shown to half-life time anthocyanins, by forming complexes with them. We studied combined effect increased metal concentrations on anthocyanins aster 'Sungal' flowers. It has found that magnesium treatment plants or detached flower buds, partially prevents colour fading at temperatures....
Environmental stresses such as high light intensity and temperature cause induction of the shikimate pathway, aromatic amino acids (AAA) pathways, pathways downstream from AAAs. The leads to production specialized metabolites that protect cells oxidative damage. regulation diverse AAA derived is still not well understood. To gain insight on regulation, we increased in red grape Vitis vinifera cv. Gamay Red cell suspension, without inducing external stress cells, characterized metabolic...
More than 40% of harvested fruit is lost, largely due to decay. In parallel, restrictions on postharvest fungicides call for eco-friendly alternatives. Fruit’s natural resistance depends mainly flavonoids and anthocyanins—which have antioxidant antifungal activity—synthesized from the phenylpropanoid pathway with phenylalanine as a precursor. We hypothesized that could induce fruit’s defense response tolerance fungal pathogens. The application mango avocado reduced anthracnose stem-end rot...
Summary Purple Petunia × hybrida V26 plants accumulate fragrant benzenoid‐phenylpropanoid molecules and anthocyanin pigments in their petals. These specialized metabolites are synthesized mainly from the aromatic amino acids phenylalanine. Here, we studied profile of secondary petunia plants, expressing a feedback‐insensitive bacterial form 3‐deoxy‐di‐arabino‐heptulosonate 7‐phosphate synthase enzyme ( AroG* ) shikimate pathway, as tool to stimulate conversion primary metabolism via acids....
Flowers are the most vulnerable plant organ to infection by necrotrophic fungus Botrytis cinerea. Here we show that pre-treatment of chrysanthemum (Chrysanthemum morifolium) flowers with phenylalanine (Phe) significantly reduces their susceptibility B. To comprehend how Phe treatment induces resistance, monitored dynamics metabolites (by GC/LC-MS) and transcriptomes RNAseq) in after cinerea infection. resulted accumulation 3-phenyllactate benzaldehyde, particular induced expression genes...
Abstract Mango fruit exposed to sunlight develops red skin and are more resistant biotic abiotic stresses. Here we show that harvested mango was at the orchard is than green Colletotrichum gloeosporioides . LCMS analysis showed high amounts of antifungal compounds, as glycosylated flavonols, anthocyanins, mangiferin in vs. skin, correlated with higher antioxidant lower ROS. However, also side has low levels flavonoids resistant, indicated induced resistance. Transcriptomes inoculated on...
Fruit constitutes a major component of our diet, providing fiber, vitamins, minerals, and many phytonutrients that promote good health. Fleshy fruits such as tomatoes already contain high levels several these ingredients. Nevertheless, efforts have been invested in increasing diversifying the content phytonutrients, carotenoids flavonoids, tomato fruits. These rely on transgenic approaches, use single-point mutations and/or quantitative trait loci affecting phytonutrients. The pigment (hp)...
Anthocyanins are secondary metabolites responsible for the red coloration of mango and apple. The color peel is essential fruit's marketability. flavonols synthesized via flavonoid pathway initiated from phenylalanine (Phe). have antioxidant, antifungal, health-promoting properties. To determine if external treatment apple trees with Phe can induce fruit peel, orchards were sprayed 1 to 4 weeks before harvest (cv. Kent, Shelly, Tommy Atkins) Cripps pink, Gala Starking Delicious). Preharvest...
