1. Indirect plant defences are well documented for the above-ground constituents of plants. Although less investigated to date, below-ground defences that mediate multitrophic interactions are equally important. Entomopathogenic nematodes (Steinernema diaprepesi) are attracted to herbivore-induced volatiles from Swingle var. (Citrus paradisi · Poncirus trifoliata) when fed upon by root weevil,D...

Citrus Huanglongbing (HLB) is becoming the most devastating citrus disease worldwide. Although no known HLB-resistant citrus species or varieties have been identified, some citrus accessions such as rough lemon are reportedly tolerant. To better understand the HLB tolerance or susceptibility mechanisms in citrus, comparative anatomical analyses of tolerant rough lemon and sensitive sweet orange...

Molecular imaging by mass spectrometry (MS) is emerging as a tool to determine the distribution of proteins, lipids, and metabolites in tissues. The existing imaging methods, however, mostly rely on predefined rectangular grids for sampling that ignore the natural cellular organization of the tissue. Here we demonstrate that laser ablation electrospray ionization (LAESI) MS can be utilized for ...

The relationship between carotenoid accumulation and the expression of carotenoid biosynthetic genes during fruit maturation was investigated in three citrus varieties, Satsuma mandarin (Citrus unshiu Marc.), Valencia orange (Citrus sinensis Osbeck), and Lisbon lemon (Citrus limon Burm.f.). We cloned the cDNAs for phytoene synthase (CitPSY), phytoene desaturase (CitPDS), zeta-carotene (car) des...

the chemical composition of the hydrolate of citrus aurantium l. (rutaceae) flowers (neroli) grown in iran, and two commercial hydrolates were analyzed by gc/ms. thirty compounds (90.3%) were identified in the hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...

Abstract Citrus aurantium amara (sour orange) belongs to one of the largest genera Rutaceae family. The species this genus are consumed worldwide as fresh or in form beverages. They include well-known crops lemons, oranges, mandarins, grapefruits, and limes. industrial processing these fruits produces high amounts waste (around 50%) which is a valuable source essential oils. Since they produced...

STUDY OBJECTIVE To evaluate the hemodynamic and electrocardiographic effects of a single dose of commercially available bitter-orange dried-fruit extract, which is increasingly being used in dietary supplements. DESIGN Randomized, double-blind, placebo-controlled, crossover study. SETTING University of Connecticut, Storrs Campus. SUBJECTS Eighteen healthy volunteers aged 18 years or older...

abstract        background and objective: peroxidases catalyze protein oxidation and lipid peroxidation. the activity of these enzymes in nerve cells is involved in causing disorders such as alzheimer's and parkinson's disease. this study investigated the effect of citrus aurantium, foeniculum vulgare and rosmarinus officinalis essential oils on activity of peroxidase enzyme.       me...

This study compared the concentration of ascorbic acid between citrus fruits collected from the farm of Kerman in Iran. Determination of ascorbic acid was carried out using a liquid chromatography coupled to a diode array detector, with reverse phase and isocratic elution. The validation parameters showed efficiency, adequate linearity, relative standard deviation values 0.02 % (n=10) for repea...
