Orange (Citrus sinensis) and grapefruit (Citrus paradise) peels were used as a source of pectin, which was extracted under different conditions. The peels are used under two states: fresh and residual (after essential oil extraction). Organic acid (citric acid) and mineral acid (sulfuric acid) were used in the pectin extraction. The aim of this study is the evaluation the effect of extraction c...

A trial was conducted in a 7-year old citrus orchard of the National Horticultural Research Institute, Nigeria, to investigate the effect of different levels of organo-mineral fertilizers as it affect the economic returns of sweet orange (Citrus sinensis L. Osbeck var. Agege 1). The treatments consisted of: (1). 10 tha Poultry 1 manure (PM), (2). 15 t ha PM, (3) 20 t ha-1 PM, (4). 0.45 t ha NPK...

In this study we investigated the prevalence of the oppA gene, encoding the oligopeptide binding protein (OppA) of the major bacterial oligopeptide uptake system (Opp), in different species of the genus Xanthomonas. The oppA gene was detected in two Xanthomonas axonopodis strains among eight tested Xanthomonas species. The generation of an isogenic oppA-knockout derivative of the Xac 306 strain...

A new genus and species, Lanceacheyla whartoni (Acariformes: Prostigmata: Cheyletidae) is described for the female, male, and teleonymph. All mites were collected from leaves of ‘Hamlin’ orange trees in Florida, U.S.A. Affinities of the new genus within Cheyletidae are discussed.

PREMISE OF THE STUDY The search for resistance/tolerance to the devastating citrus huanglongbing disease (syn. HLB or citrus greening) is generating an increasing number of new plants of diverse genetic makeup. As the increasing number of new plants require more space, resources, and time, the need for faster and more efficient HLB screening tests becomes crucial. METHODS AND RESULTS The leaf...
