This article reports on the bioactivities of citrus extracts (citrus extract, lemon extract, and neroli) toward Saccharomyces cerevisiae, Zygosaccharomyces bailii, Zygosaccharomyces rouxii, Pichia membranifaciens, and Rhodotorula bacarum. The bioactivities of the extracts (from 10 to 100 ppm) were evaluated through a microdilution method; thereafter, citrus extracts (0 to 80 ppm) were tested in...
Viroids are small (246-401 nucleotides), single-stranded, circular RNA molecules that infect several crop plants and can cause diseases of economic importance. Citrus are the hosts in which the largest number of viroids have been identified. Citrus exocortis viroid (CEVd), the causal agent of citrus exocortis disease, induces considerable losses in citrus crops. Changes in the gene expression p...
Targeted therapy has been a very promising strategy of drug development research. Many molecular mechanims of diseases have been known to be regulated by abundance of proteins, such as receptors and hormones. Chemoprevention for treatment and prevention of diseases are continuously developed. Pre-clinical and clinical studies in chemoprevention field yielded many valuable data in preventing the...
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...
The brown citrus aphid, Toxoptera citricida (Kirkaldy), is considered the primary vector of citrus tristeza virus, a severe pathogen which causes losses to citrus industries worldwide. The alate (winged) form of this aphid can readily fly long distances with the wind, thus spreading citrus tristeza virus in citrus growing regions. To better understand the biology of the brown citrus aphid and t...
Boron (B) toxicity is observed in some citrus orchards in China. However, limited data are available on the molecular mechanisms of citrus B-toxicity and B-tolerance. Using cDNA-AFLP, we identified 20 up- and 52 down-regulated genes, and 44 up- and 66 down-regulated genes from excess B-treated Citrus sinensis and Citrus grandis roots, respectively, thereby demonstrating that gene expression pro...
citrus is one of the most important fruit crops in iran. among the citriculture areas of iran, mazandaran province has the highest acreage (about 100,000 ha), production and number of varieties nationwide. unauthorized importation of citrus species and cultivars and propagation by growers and nurserymen have led to perpetuation and spread of virus, viroid and other graft-transmissible pathogens...
The genus Phyllosticta occurs worldwide, and contains numerous plant pathogenic, endophytic and saprobic species. Phyllosticta citricarpa is the causal agent of Citrus Black Spot disease (CBS), affecting fruits and leaves of several citrus hosts (Rutaceae), and can also be isolated from asymptomatic citrus tissues. Citrus Black Spot occurs in citrus-growing regions with warm summer rainfall cli...
The shape-sorter puzzle is a quintessential toy that children play with to learn how to fit objects in holes. Psychology research shows that human children learn object fitting during an early developmental period. We implemented similar developmental learning in our robot using random exploratory behaviors and proprioceptive feedback with the shape sorter puzzle. Analysis shows that successful...
