Modern agriculture requires alternative practices that improve crop growth without negatively affecting the environment, as resources such as water and arable land grow scarcer while the human population continues to increase. Grafting is a cultivation technique that allows the plant to be more efficient in its utilization of water and nutrients, while nanoscale material engineering provides the opportunity to use much smaller quantities of consumables compared to conventional systems but with similar or superior effects...

Bacterial fruit blotch (BFB), caused by the gram-negative bacterium Acidovorax citrulli, is a serious economic threat to cucurbit crop production worldwide. A. citrulli strains can be divided into two genetically distinct groups with group I strains infecting a range of cucurbit species, and group II strains being predominantly associated with watermelon. Group I and II A. citrulli strains differ in their arsenal of type III secreted (T3S) effector proteins and we hypothesize that these effectors are critical for cucurbit host preference...

Zucchini yellow mosaic virus (ZYMV) causes serious damage in a great number of cucurbits and control measures are necessary. Transgenic cucurbits expressing parts of ZYMV genome were shown to be resistant against the cognate virus. A non-transgenic approach involving exogenous application of dsRNA has also been shown to induce resistance in tobacco against cucumber mosaic virus (CMV) and tobacco mosaic virus (TMV). In the present study, dsRNA molecules derived from the helper component-proteinase (HC-Pro) and coat protein (CP) genes of the ZYMV_DE_2014 isolate were produced in vitro...

Irregular vascular dilatation in the antrum or the cardia of the stomach can be the cause of severe gastrointestinal bleeding. The first term for it - in the beginning of the 50's of the previous century - was GAVE (Gastric Antral Vascular Ectasia) since at that time no similar phenomenon had been registered before. A quarter of a century later, after publishing a few cases, a witty internist described it as "watermelon stomach" because the macroscopic picture is similarly looking as the aforesaid fruit's appearing...

Raw watermelon juice was concentrated in a laboratory-scale flat-plate ultrafiltration system incorporating polyethersulfone membranes with a molecular weight cutoff of 5 kDa. The experiments have been carried out over a wide range of transmembrane pressures (100-300 kPa). The effect of ultrafiltration with molecular weight cutoff of 5 kDa polyethersulfone membrane on concentrate properties is reported. The total soluble solid content of the permeate was found to be very good, while the ascorbic acid content was on the lower side as compared to feed...

We discovered an unexpected mode of bimodal distribution of stable and plastic traits, which was consistent for homologous traits of 32 varieties of seven species both in well-irrigated fields and dry conditions. We challenged archived genetic mapping data for 36 fruit, seed, flower and yield traits in tomato and found an unexpected bimodal distribution in one measure of trait variability, the mean coefficient of variation, with some traits being consistently more variable than others. To determine the degree of conservation of this distribution among higher plants, we compared 18 homologous phenotypes, including yield and seed production, across different crop species grown in a common 'crop garden' experiment...

The Gram-reaction-negative, aerobic, white- to pale-yellow-coloured and rod-shaped bacterium with a single polar flagellum or a stalk, designated strain 7F14T, was isolated from rhizosphere soil of cultivated watermelon (Citrullus lanatus) collected from Hefei, China. Growth of strain 7F14T was observed at pH 6.0-9.0, 10-30 °C and in the presence of 0-1 % (w/v) NaCl. Cells were catalase-negative and oxidase-positive. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain 7F14T formed a phyletic lineage within the genus Caulobacter of the family Caulobacteraceae and showed the highest 16S rRNA gene sequence similarities to Caulobacter henricii ATCC 15253T (98...

Cucumber green mottle mosaic virus (CGMMV) was first described in 1935 infecting cucumber, making it one of the first plant viruses to be described. Its initial distribution occurred out of England to other countries. This was followed by its subsequent distribution from England and these other countries. This process increased slowly between 1935 and 1985, faster between 1986 and 2006, and rapidly between 2007 and 2016. The discovery that it diminished cucurbit fruit yields and quality, especially of watermelon, prompted a substantial research effort in worst-affected countries...

Cultivar choice is at the heart of cropping systems and resistant cultivars should be at the heart of disease management strategies whenever available. They are the easiest, most efficient and environmentally friendly way of combating viral diseases at the farm level. Among the melon genetic resources, Vat is a unique gene conferring resistance to both the melon aphid Aphis gossypii and the viruses it carries. The 'virus side' of this pleiotropic phenotype is seldom regarded as an asset for virus control. Indeed, the effect of Vat on virus epidemics in the field is expected to vary according to the composition of aphid populations in the environment and long-term studies are needed to draw a correct trend...

Watermelon peel waste was hydrothermally carbonized under 190°C and 260°C for 1h, 6h, and 12h, respectively. The hydrochar and spent liquor were collected and assayed for their properties. The results indicated that hydrochar yield was 2-5% and 46-95% on fresh and dry matter, respectively. Low temperature (190°C) was conducive to high conversion efficiency. The hydrochar had higher C/N ratio (22.19-26.86), more alkyl C, aryl C, and carbonyl C, but lower H/C (0.98-1.22) and O/C ratios (0.13-0.38), and less O-alky C, carboxylic C, compared with feedstock...

Grafting has become an imperative for intensive vegetable production since chlorofluorocarbon-based soil fumigants were banned from use on grounds of environmental protection. Compelled by this development, research into rootstock-scion interaction has broadened the potential applications of grafting in the vegetable industry beyond aspects of soil phytopathology. Grafting has been increasingly tapped for cultivation under adverse environs posing abiotic and biotic stresses to vegetable crops, thus enabling expansion of commercial production onto otherwise under-exploited land...

BACKGROUND: Self-monitoring of blood glucose (SMBG) is an important component of management for diabetes mellitus (DM), especially in T1DM and T2DM patients who are on insulin therapy. Adequate blood glucose monitoring and prompt intervention are necessary to prevent blood glucose (BG) fluctuation and delay long-term diabetes complications. People with DM are advised to clean their hands before SMBG to remove any dirt or food residue that might affect the reading. AIM: The study tested the hypothesis that falsely elevated BG levels from fingertip occur after peeling or handling fruits in an unwashed hand...

l-Citrulline is a nonessential amino acid precursor of arginine and indirectly a precursor of nitric oxide (NO), which is a vasodilator and increases mitochondrial respiration. On the other hand, the antioxidant pomegranate ellagitannins are precursors of urolithin A, which has been associated with mitophagy and increased muscle function. To elucidate if a single dose of watermelon enrichment with these compounds could have a positive effect after high-intensity exercise (eight sets of eight repetitions of half-squat exercise), a double-blind randomized crossover in vivo study was performed in healthy male subjects (n = 19)...

To employ a microsphere immunoassay (MIA) to simultaneously detect multiple plant pathogens (potyviruses, Watermelon silver mottle virus, Melon yellow spot virus, and Acidovorax avenae subsp. citrulli) in actual plant samples, several factors need to be optimized and rigorously validated. Here, a simple extraction method using a single extraction buffer was successfully selected to detect the four pathogens in various cucurbit samples (cucumber, cantaloupe, melon, and watermelon). The extraction method and assay performance were validated with inoculated and field cucurbit samples...
