In the attempt to identify the causal agent of Citrus chlorotic dwarf disease (CCDD), a virus-like disorder of citrus, the small RNA fraction and total DNA from symptomatic citrus plants were subjected to high-throughput sequencing. DNA fragments deriving from an apparently new geminivirus-like agent were found and assembled by NGS to re-construct the entire viral genome. The newly identified v...
سمیت تنفسی اسانس های فرار پوست نارنگی،citrus reticulata blanco (rutaceae) ، لیمو،c. limon l. ، و نارنج،c. aurantium l.، روی تخم، لارو و حشرات کامل سوسک چهار نقطه ای حبوبات، callosobruchus maculatus (f.)، در دمای 1 ± 27 درجه سلسیوس و رطوبت نسبی 5 ± 60 درصد در تاریکی مورد بررسی قرار گرفت. اسانس ها به روش تقطیر با آب و از پوست میوه ها استخراج شدند و با آنالیز gc و gc/ms مورد شناسایی قرار گرفتند. ل...
Production management is the best and foremost factor in exploiting the production factors more desirably and advantageously. Accordingly, the present study sought to evaluate the factors affecting the gardening management skills among citrus farmers in Sari, north of Iran. The statistical population for the study was 12,800 people. The stratified random sampling using the Cochran test was ap...
Greening is a severe and widespread disease of citrus in two main citrus growing areas of the world, Asia and Africa. It is caused by an uncultured phloem restricted bacterium that we have recently characterized from the sequence of its 16S ribosomal DNA. The bacterium is a new "Candidatus' genus, Liberobacter, in the alpha subdivision of the proteobacteria, and two 'Candidatus species' have be...
We generated source-sink imbalances by defoliation and sucrose supplementation by stem injection, to investigate effects of carbohydrate availability on fruitlet growth and abscission in cv. Okitsu of Satsuma mandarins (Citrus unshiu (Mak.) Marc.). Partial defoliation promoted fruitlet abscission, whereas sucrose supplementation increased citrus fruit set by more than 10%. Moreover, when applie...
Huanglongbing (HLB) is currently the most destructive disease of citrus worldwide. Although there is no immune cultivar, field tolerance to HLB within citrus and citrus relatives has been observed at the USDA Picos farm at Ft. Pierce, Florida, where plants have been exposed to a very high level of HLB pressure since 2006. In this study, we used RNA-Seq to evaluate expression differences between...
In a previous study we found that 50% ethanol extracts of immature fruits of Citrus unshiu (satsuma mandarin) have anti-allergic effects against the Type I, II and IV allergic reactions. However, many adverse interactions between citrus fruit, especially grapefruit juice, and drugs have been reported due to the inhibition of cytochrome P450 (CYP) activities. The purpose of this study was to exa...
Anastrepha serpentina (Wiedemann) is recorded for the first time in citrus (Rutaceae) in Brazil. Specimens were obtained from sweet orange (Citrus sinensis) sampled in the municipalities of Belém and Capitão Poço, and from mandarin orange (Citrus reticulata) from Tomé-Açu, state of Pará, Brazil.
Departme Tusa, N., J.W. Grosser, and F.G. Gmitter, Jr. 1990. Plant regeneration of ‘Valencia’ sweet orange, ‘Femminello’ lemon, and the interspecific somatic hybrid following protoplast fusion. J. Amer. Soc. Hort. Sci. 115:1043– 1046. Vardi, A., P. Arzee-Gonen, A. Frydman-Shani, and S. Bleichman. 1989. Protoplast fusion mediated transfer of organelles from Microcitrus and Citrus and regeneratio...
A total of 39 aroma compounds were detected in the essential oil of Citrus nagato-yuzukichi Tanaka (nagato-yuzukichi) by gas chromatography-mass spectrometry (GC-MS). The essential oil was characterized by a high percentage of monoterpene hydrocarbons (12 components, 90.52%). The composition pattern of essential oil in C. nagato-yuzukichi was fairly similar to that of Citrus sudachi Hort. ex Sh...
