background & aims of the study: today, the environment pollution with heavy metals has increased. it is important to study various types of pollutions specially those regarding fruits. the effect of pollutions on food safety for human consumption is a global concern.  this study was conducted for health assessment of heavy metals pollution (cadmium, lead, and arsenic) in citrus marketed in tehr...

Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in beta‐carotene and adapted to local growing environments have the potential to significantly reduce the prevalence of vitamin A deficiency. One such example is the orange sweet potato (OSP). Because of its distinctive orange color, which is in contrast to th...

Abstract: The objective of this work was to determine the influence eight rootstocks on yield, fruit quality, and survival 'Pêra CNPMF D6' sweet orange (Citrus sinensis) trees grown under rainfed conditions in a cohesive soil Brazilian Northeast. In 2014-2018, fruits, planted 1997 were evaluated randomized complete block design. Yield assessed using annual production, yield efficiency, alternat...

there have been efforts to overcome the problem in treatment of cancer using medicinal plants. it has been shown that citrus essential oil of contains different terpens with antitumor activities. in this study we sought to determine the cytotoxicity of essential oils of iranian citrus limon (l.), c. medica (l.), c. sinsensis (l.) peels on cancer cell lines. essential oils were prepared by hydro...

MYB family genes are widely distributed in plants and comprise one of the largest transcription factors involved in various developmental processes and defense responses of plants. To date, few MYB genes and little expression profiling have been reported for citrus. Here, we describe and classify 177 members of the sweet orange MYB gene (CsMYB) family in terms of their genomic gene structures a...

Vacuolar pyrophosphatase (V-PPase) from juice cells of 3 citrus varieties (differing in their vacuolar pH) were partially characterized using purified tonoplast vesicles. Total V-PPase activity was highest in vesicle samples from sweet limes with vacuolar pH of 5.0, while samples from acid limes (with lowest vacuolar pH of 2.0) had the minimal total V-PPase activity. Samples from 'Valencia' ora...

Abstract As the bacterial etiologic agent causing citrus canker (CBC), Xanthomonas citri subsp. (Xcc) seriously impacts plantation and fruit production globally. In an earlier study, we demonstrated that CsBZIP40 can positively impact CBC resistance in sweet orange (Citrus sinensis). However, mechanistic basis for protective benefits conferred by is yet to be delineated. Here, show regulates re...

Xylella fastidiosa is a xylem-limited bacterium that causes citrus variegated chlorosis disease in sweet orange. There is evidence that X. fastidiosa interacts with endophytic bacteria present in the xylem of sweet orange, and that these interactions, particularly with Methylobacterium mesophilicum, may affect disease progress. However, these interactions cannot be evaluated in detail until eff...
