High impact information on Citrus sinensis

• Previous studies on the regulation of gpx1, the Citrus sinensis gene encoding phospholipid hydroperoxide isoform, led to the conclusion that salt-induced expression of gpx1 transcript and its encoded protein is mediated by oxidative stress [1].
• The salt-soluble, globulin protein fraction (designated citrin) was purified from Citrus sinensis cv Valencia seeds [2].
• We have purified a Zn-binding protein (ZBP) from phloem tissue of healthy and blight-affected citrus (Citrus sinensis [L.] Osbeck on Citrus jambhiri [L.]) [3].
• NO donors such as sodium nitroprusside (SNP) and S-nitroso-N-acetylpenicillamine inhibited growth and caused death in suspension-cultured cells of Citrus sinensis [4].
• Differential expression of two cinnamate 4-hydroxylase genes in 'Valencia' orange (Citrus sinensis Osbeck) [5].

Biological context of Citrus sinensis

• DNA sequence analysis revealed 76% sequence identity between clone AFN3 and a Citrus sinensis glutathione peroxidase-like cDNA, while significant sequence similarities with known genes were not found for other clones [6].
• CMA/DAPI double staining and FISH methods using rDNA and telomere specific repeated sequences as probes were applied to characterize the large amount of heterochromatin in the telomeric regions of 'Trovita' orange (Citrus sinensis Osbeck) chromosomes [7].

Associations of Citrus sinensis with chemical compounds

• A comparison of the phenolic compositions, the ascorbic acid contents and the antioxidant activities of fresh Sicilian orange juices from pigmented (Moro, Tarocco and Sanguinello) and non-pigmented (Ovale, Valencia and Navel) varieties of orange (Citrus sinensis L. Osbeck), was undertaken [8].
• Upon harvest, young, fully expanded 'Valencia' orange (Citrus sinensis) leaves ( approximately 60-d-old) exhibited two phases of ethylene production [9].
• Characterization of Pinalate, a novel Citrus sinensis mutant with a fruit-specific alteration that results in yellow pigmentation and decreased ABA content [10].
• To understand the regulation of ABA biosynthesis in Citrus, two full-length cDNAs (CsNCED1 and CsNCED2) encoding NCEDs were isolated and characterized from the epicarp of orange fruits (Citrus sinensis L. Osbeck) [11].
• We analyzed the effects of nitrate availability on growth of Navelina (Citrus sinensis (L.) Osbeck) scions grafted on three citrus rootstocks differing in salt tolerance: Carrizo citrange (Citrus sinensis (L.) Osbeck x Poncirus trifoliata (L.) Raf.), Citrus macrophylla Wester and Cleopatra mandarin (Citrus reshni Hort. ex Tanaka) [12].

Gene context of Citrus sinensis

• Identification of two chilling-regulated 1-aminocyclopropane-1-carboxylate synthase genes from citrus (Citrus sinensis Osbeck) fruit [13].
• The compositional characterisation and antioxidant activity of fresh juices from sicilian sweet orange (Citrus sinensis L. Osbeck) varieties [8].
• Five-year-old 'Spring' navel (Citrus sinensis (L.) Osbeck) orange trees were completely defruited, 50% defruited or left fully laden to study effects of fruit load on concentrations of nitrogen (N) and carbohydrate, net assimilation of CO2 (Ac) and stomatal conductance (gs) of mature leaves on clear winter days just before fruit harvest [14].
• BACKGROUND: It is important to study the crossreactivity between orange tree pollen (OTPE) and orange fruit (OFE) due to the high incidence of pollen/food-related allergies worldwide [15].
• The pectin methylesterase (PME; EC 3.1.1.11) present in a commercial orange peel enzyme preparation was characterized to establish its identity among the multiple PME isozymes present in Valencia orange (Citrus sinensis L.) peel [16].

Analytical, diagnostic and therapeutic context of Citrus sinensis

• Desiccation and freezing tolerance of embryonic axes from Citrus sinensis [L.] osb. pretreated with sucrose [17].
