The present study aims to analyse phylogenetic relationships, using internal transcribed spacer sequence data of ribosomal DNA (rDNA), across 24 Citrus species and close relatives by the evaluation of several parameters such as nucleotide substitution (r), nucleotide diversity (π) and the estimated values of transition/transversion bias (R). The observed results indicated the presence of a wide...

the genus fusarium is a species rich genus. different media are required to study themorphological characters and classify different species, a time consuming technique. in this study pecticzymograms were used to identify species and form species of fusarium isolates. fusarium isolates (318) wereobtained from different areas and hosts in isfahan province, iran. isolates were identified to speci...

Huanglongbing (HLB) is a severe citrus (Citrus spp.) disease associated with the bacteria genus Candidatus Liberibacter, detected in Brazil in 2004. Another bacterium was found in association with HLB symptoms and characterized as a phytoplasma belonging to the 16SrIX group. The objectives of this study were to identify potential leafhopper vectors of the HLB-associated phytoplasma and their ho...

UNLABELLED The rich wealth of Citrus genetic resources makes India to enjoy a remarkable position in the "Citrus belt of the world". We have developed CIBMAN, a unique database on Citrus biodiversity of Manipur which comprises 33 accessions collected through extensive survey for more than three years. CIBMAN provides integrated access to Citrus species through sophisticated web interface which ...

Citrus, one of the important fruit crops of the tropics and subtropics, is grouped as a glycophyte. The deleterious effects of salt stress lead to reduction in fruit yield and quality. The response of different citrus species to different salt(s) further brings differential responses, when fruit quality is concerned. The possible mechanisms (physical, nutritional, biochemical), which plants ada...

A morphometric and molecular characterization of Brevipalpus sp. close to the group cryptic species within californicus s.l. bearing only one solenidion on tarsus II was conducted, its capacity acquire inoculate citrus leprosis virus C (CiLV-C) orchid fleck virus, strain-citrus (OFV-citrus), determined. For study, photomicrographs mites from two colonies kept in laboratory were taken: derived a...

Citrus farming is currently a main sector in Africa general, particularly the sub-Saharan region. Cameroon has been expanding since cocoa crisis and thanks to its financial economic benefits. The research aim was evaluate parasitism of Loranthaceae on citrus trees Mongo department. Direct observations were made canopy 796 seven arrondissements, included species identification, growing their fol...

Citrus essential oils are very complex matrices which contain numerous compounds of different chemical classes. These compounds are generally divided into two fractions: the volatile fraction, which is the most representative, and ranges between 85 and 99% in the different cold-pressed citrus oils, and the non-volatile residue, which ranges between 1 and 15%. The development of new instrumental...

Flavanones constitute the majority of flavonoids in citrus fruits such as sweet (Citrus sinensis) and sour oranges (C. aurantium) and their near relatives—tangerines/mandarins (C. reticulata), tangors and tangelos. The relevant chemical analytic literature was searched, abstracted, documented, standardized, examined for quality, enumerated, and summarized in a database for these citrus flavanon...
