The Asiatic citrus psyllid (Diaphorina citri Kuwayama [Hemiptera: Sternorrhyncha: Psyllidae] is a vector of huanglongbing (citrus greening), a devastating disease of citrus caused by phloem-limited bacteria. Growing guava (Psidium guajava) as an intercrop appears to be a successful means of reducing psyllid numbers within citrus orchards; however, the mechanism by which such a reduction is achi...

The usage and acceptability of biological control methods are set to increase in agriculture in the future because of food safety and pesticide residue issues. Biological control implementation in Turkey started with control of cottony cushion scale Icerya purchasi (Homoptera: Margarodidae) through the introduction and release of Rodolia cardinalis (Coleoptera: Coccinellidae) in citrus plantati...

The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is the primary vector of Candidatus Liberibacter asiaticus (Las) associated with huanglongbing, or citrus greening, the most devastating citrus (Citrus spp.) disease worldwide. Here, we developed a new “excised-leaf assay” that can speed upLas-inoculativity tests on Asian citrus psyllid from the current 3Ð12mo (when usi...

Citrus is grown in more than 125 countries in a belt within 35° latitude north or south of the equator. The major limiting factor to citrus production is a requirement that the occurrence of freezing temperatures be of very short duration. Within the family Rutaceae, the genera Citrus (oranges, mandarins, pomelos, grapefruit, lemons, limes and citrons), Fortunella (kumquats) and Poncirus (trifo...

Sweet orange (Citrus sinensis) is one of the major cultivated and most-consumed citrus species. With the goal of enhancing the genomic resources in citrus, we surveyed, developed and characterized microsatellite markers in the ≈347 Mb sequence assembly of the sweet orange genome. A total of 50,846 SSRs were identified with a frequency of 146.4 SSRs/Mbp. Dinucleotide repeats are the most frequen...

Citrus fruits, which are cultivated worldwide, have been recognized as some of the most high-consumption fruits in terms of energy, nutrients and health supplements. What is more, a number of these fruits have been used as traditional medicinal herbs to cure diseases in several Asian countries. Numerous studies have focused on Citrus secondary metabolites as well as bioactivities and have been ...

Background The human microbiome project [1] is the first systematic and large-scale survey of microbial communities present in a eukaryotic metagenome. The availability of low-cost high-throughput next-generation sequencing technologies that enable us to sequence eukaryotes to a high depth of coverage presents an opportunity for in silico discovery of endosymbionts. We describe a method for min...

'Mexican' lime (Citrus aurantifolia Swingle) was transformed with constructs that contained chimeric promoter-gus gene fusions of phloem-specific rolC promoter of Agrobacterium rhizogenes, Arabidopsis thaliana sucrose-H(+) symporter (AtSUC2) gene promoter of Arabidopsis thaliana, rice tungro bacilliform virus (RTBV) promoter and sucrose synthase l (RSs1) gene promoter of Oryza sativa (rice). Hi...

Agricultural associations of a socio-economic nature have been and continue to be a basic structural feature of the agribusiness sector and rural development in Spain, both in the social and economic and land use spheres. Taking into account the current significance of these entities and the future prospects, in this paper we analyse the Internet presence of the Spanish citrus co-operatives. Th...
