The antioxidant activity of rosemary (Rosmarinus officinalis L.) extracts is mainly due to phenolic abietane diterpenes and acids such as rosmarinic acid. In this study a comprehensive characterization non-water-soluble water-soluble from was achieved by liquid chromatography coupled electrospray mass spectrometry. these their respective major compounds (carnosic acid, carnosol, rosmadial, genkwanin, acid) analyzed compared using different in vitro systems. Whereas carnosic carnosol...
Tomato (Solanum lycopersicum) is a globally important crop with an economic value in the tens of billions dollars, and significant supplier essential vitamins, minerals, phytochemicals human diet. Shelf life key quality trait related to alterations cuticle properties remodeling fruit cell walls. Studies transgenic tomato plants undertaken over last 20 years have indicated that range pectin-degrading enzymes are involved wall remodeling. These studies usually silencing only single gene it has...

The aim of this study was to assess whether endosperm-specific carotenoid biosynthesis influenced core metabolic processes in maize embryo and endosperm how global seed metabolism adapted expanded biosynthetic capacity. Although enhancement targeted the kernels, a concurrent up-regulation sterol fatty acid measured. Targeted terpenoid analysis, non-targeted metabolomic, proteomic, transcriptomic profiling revealed changes especially carbohydrate transgenic line. In-depth analysis data,...
Tomato and its processed products are one of the most widely consumed fruits. Its domestication, however, has resulted in loss some 95% genetic chemical diversity wild relatives. In order to elucidate this diversity, exploit potential for plant breeding, as well understand biological significance, analytical approaches have been developed, alongside production crosses relatives with commercial varieties. article, we describe a multi-platform metabolomic analysis, using NMR, mass spectrometry...
Abstract High temperatures can negatively influence plant growth and development. Besides yield, the effects of heat stress on fruit quality traits remain poorly characterised. In tomato, insights into how fruits regulate cellular metabolism in response to could contribute development heat‐tolerant varieties, without detrimental quality. present study, changes occurring wild type tomato after exposure transient have been elucidated at transcriptome, metabolite level. An impact was evident as...
Abstract Background Whiteflies are a threat to cassava ( Manihot esculenta ), an important staple food in many tropical/subtropical regions. Understanding the molecular mechanisms regulating cassava’s responses against this pest is crucial for developing control strategies. Pathogenesis-related (PR) protein families integral part of plant immunity. With availability whole genome sequences, annotation and expression programs full complement PR genes organism can now be achieved. An...
Summary Roots, tubers, and bananas (RTB) are vital staples for food security in the world's poorest nations. A major constraint to current RTB breeding programmes is limited knowledge on available diversity due lack of efficient germplasm characterization structure. In recent years large‐scale efforts have begun elucidate genetic phenotypic collections populations and, yet, biochemical measurements often been overlooked despite metabolite composition being directly associated with agronomic...
Isoprenoids, including dolichols (Dols) and polyprenols (Prens), are ubiquitous components of eukaryotic cells. In plant cells, there two pathways that produce precursors utilized for isoprenoid biosynthesis: the mevalonate (MVA) pathway methylerythritol phosphate (MEP) pathway. this work, contribution these to biosynthesis Prens Dols was addressed using an in planta experimental model. Treatment plants with pathway-specific inhibitors analysis effects various light conditions indicated...
The presence of stilbenes in wine is becoming an important issue due to their claimed relation a low incidence coronary diseases and increasing implication as cancer chemopreventive neuroprotective agents. Total resveratrol content, quantified glucoside aglycone forms resveratrol, has been determined survey 45 Monastrell monovarietal Spanish red types (around 135 samples), belonging Alicante Bullas appellations. average between ratio glucoside/aglycone these wines was considerably high,...
Cassava (Manihot esculenta Crantz) provides food security for over 500 million people in Sub-Saharan Africa (SSA). Whitefly (Bemisia tabaci) is a pest this region that result ca. 50% crop yield losses. Thus, it important to develop approaches will generate new varieties tolerant advance the region. Two parental cassava varieties, ECU72 whiteflies and COL2246 susceptible line have been used bi-parental populations. The F1 generation has screened whitefly resistance progeny identified...
The extracellular space (apoplast) in plants is a key battleground during microbial infections. To avoid recognition, the bacterial model phytopathogen Pseudomonas syringae pv. tomato DC3000 produces glycosyrin. Glycosyrin inhibits plant-secreted β-galactosidase BGAL1, which would otherwise initiate release of immunogenic peptides from flagellin. Here, we report structure, biosynthesis, and multifunctional roles High-resolution cryo–electron microscopy chemical synthesis revealed that...
Pigmented Bacillus spp. with probiotic properties have been isolated. In the yellow‐/orange‐coloured strains, carotenoid pigments present characterized. contrast, carotenoids in isolates coloured red await identification. The article reports progress on elucidation of pigment biosynthetic pathway these red‐pigmented firmus strains. A combination UV/Vis, chromatographic and mass spectrometry (MS) has revealed predominant end‐point to be methyl 4,4′‐diapolycopene‐dioate after transmethylation....
Ketolated and hydroxylated carotenoids are high-value compounds with industrial, food, feed applications. Chemical synthesis is currently the production method of choice for these compounds, no amenable plant sources readily available. In this study, 4,4' β-oxygenase (crtW) 3,3' β-hydroxylase (crtZ) genes from Brevundimonas sp. SD-212 were expressed under constitutive transcriptional control in Nicotiana glauca, which has an emerging potential as a biofuel biorefining feedstock. The...
Cassava whitefly outbreaks were initially reported in East and Central Africa cassava (Manihot esculenta Crantz) growing regions the 1990's have now spread to other geographical locations, becoming a global pest severely affecting farmers smallholder income. Whiteflies impact plant yield via feeding vectoring mosaic brown streak viruses, making roots unsuitable for food or trading. Deployment of virus resistant varieties has had little on populations therefore development is also necessary...
The aim of this study was to test the efficacy an antioxidant/anti-inflammatory supplement containing standardized lemon verbena (Aloysia triphylla, Lippia citriodora) extract and fish oil omega-3 fatty acid in a human pilot trial as alternative treatment for joint management.First, antioxidant activity determined through oxygen radical absorbance capacity (ORAC) assay. In randomized, double-blinded placebo-controlled trial, 45 subjects with pain discomfort received nutritional or placebo 9...
