Boron (B) deficiency stress is frequently observed in citrus orchards and causes considerable loss of productivity and fruit quality. Carrizo citrange (Cc) has been reported as a rootstock more tolerant to B deficiency than Trifoliate orange (To). The 'Newhall' navel orange (Ns) performed better when grafted onto Cc (Ns/Cc) than when grafted onto To (Ns/To) under long-term B deficiency. The pre...

UNLABELLED PREMISE OF THE STUDY We developed and characterized five polymorphic microsatellite loci from an AC-enriched genomic library of a rare tree, Tapiscia sinensis, and six compound microsatellite primers using a dual-suppression-PCR-based approach, to investigate geographical genetic structure. • METHODS AND RESULTS The polymorphism of these loci was assessed in 102 samples collecte...

BACKGROUND Citrus sinensis juice (CSJ) is a rich source of dietary flavonoids which reduce the risk of adverse cardiovascular events. This study aimed to examine the effects of four-week intake of natural and commercial orange (Citrus sinensis) juice on blood pressure in healthy volunteers. METHODS In this single-blind randomized crossover study, 22 healthy subjects (age: 18-59 years old) wer...

ABSTRACT Strains of Xylella fastidiosa, isolated from sweet orange trees (Citrus sinensis) and coffee trees (Coffea arabica) with symptoms of citrus variegated chlorosis and Requeima do Café, respectively, were indistinguishable based on repetitive extragenic palindromic polymerase chain reaction (PCR) and enterobacterial repetitive intergenic consensus PCR assays. These strains were also indis...

In vitro organogenesis of citrus was studied for the genotypes Citrus sinensis cv. ‘Natal’, C. limonia, C. volkameriana, and C. aurantium, with the use of epicotyl segments-derived explants, cultured in MT salts and vitamins medium supplemented with different concentrations of 6-benzylaminopurine (BAP – 0.0; 0.5; 1.0; 1.5, or 2.0 mg L-1). For the recalcitrant genotypes C. limonia and C. auranti...

The family of aquaporins (AQPs), or major intrinsic proteins (MIPs), includes integral membrane proteins that function as transmembrane channels for water and other small molecules of physiological significance. MIPs are classified into five subfamilies in higher plants, including plasma membrane (PIPs), tonoplast (TIPs), NOD26-like (NIPs), small basic (SIPs) and unclassified X (XIPs) intrinsic...

the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...

Citrus produced in the southwestern United States is often irrigated with perchlorate-contaminated water. This irrigation water includes Colorado River water which is contaminated with perchlorate from a manufacturing plant previously located near the Las Vegas Wash, and ground water from wells in Riverside and San Bernardino counties of California which are affected by a perchlorate plume asso...

Traditionally, Sicilian blood oranges (Citrus sinensis) have been associated with cardiovascular health, and consumption has been shown to prevent obesity in mice fed a high-fat diet. Despite increasing consumer interest in these health-promoting attributes, production of blood oranges remains unreliable due largely to a dependency on cold for full color formation. We show that Sicilian blood o...
