Currently, the impact of nanoparticles (NPs) on plants is a provocative and promising field. As well-known, dicotyledon and monocotyledon show significant differences in the structural features of the roots and iron absorption mechanisms, and hence it is very meaningful to carry out the comparative study on the diverse impact of NPs on the physiological behaviors of monocotyledon and dicotyledon. In this study, two typical monocotyledon and dicotyledon crops, watermelon (Citrullus lanatus) and maize (Zea mays L...

Since the 1950s, research on the animal neurohormone melatonin, has focused on its multi-regulatory effect on patients suffering from insomnia, cancer, and Alzheimer's. In plants, melatonin plays major role in plant growth and development, and is inducible in response to diverse biotic and abiotic stresses. However, studies on the direct role of melatonin in disease suppression and as a signaling molecule in host-pathogen defense mechanism are lacking. This study provides insight on the predicted biosynthetic pathway of melatonin in watermelon (Citrullus lanatus) and how application of melatonin, an environmental-friendly immune inducer, can boost plant immunity and suppress pathogen growth where fungicide resistance and lack of genetic resistance are major problems...

Gastric antral vascular ectasia or "watermelon stomach" is a significant cause of nonvariceal upper GI bleeding and is characterized by red, tortuous ectatic vessels along longitudinal folds in the gastric antrum. The existing literature links GAVE to patients with cirrhosis, scleroderma, bone marrow transplantation, and chronic renal failure among other associations, but its pathophysiology remains ill-defined. Over 30 cases of hematopoietic stem cell transplant-related GAVE (HSCT-GAVE) have been reported in the literature to date and there are likely many more that go undiagnosed or are attributed to another cause of upper gastrointestinal bleeding...

Polyploidization is a key driving force that plays a vital role in the evolution of higher plants. Autopolyploid plants often demonstrate altered physiology phenomena due to the different genome composition and gene expression patterns. For example, autopolyploid plants are more resistant to stresses than their homologous diploid ancestors. Soil salinity and secondary salinization are two vital factors affecting crop production which severely limit the sustainable development of agriculture in China. Polyploid plants are important germplasm resources in crop genetic improvement due to their higher salt tolerance...

Spatiotemporal dynamics studies of crop pests enable the determination of the colonization pattern and dispersion of these insects in the landscape. Geostatistics is an efficient tool for these studies: to determine the spatial distribution pattern of the pest in the crops and to make maps that represent this situation. Analysis of these maps across the development of plants can be used as a tool in precision agriculture programs. Watermelon, Citrullus lanatus (Thunb.) Matsum. and Nakai (Cucurbitales: Cucurbitaceae), is the second most consumed fruit in the world, and the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is one of the most important pests of this crop...

Qualitative and quantitative analysis and odor active value (OAV) calculation were applied to identify the aroma-active compounds of fresh watermelon juice in five varieties: Seedless, Jingxin, Lianfa, Qilin, and Texiaofeng. Principal component analysis and cluster analysis were selected to compare the similarity and difference among watermelons juices. Fifty-five volatiles were identified in watermelon juice in five varieties, among which 6 volatiles were identified for the first time in watermelon. (Z)-6-nonenal, (E, Z)-2,6-nonadienal, (E)-2-nonenal, and (E, E)-2,4-nonadienal contributed greater to aroma profiles than alcohols due to lower threshold through odor active values...

A novel magnetic heavy metal adsorbent was prepared via diethylenetriamine (DETA) modification on magnetic hydrothermal carbon, with glucose and sugar-containing waste water as the carbon source. The prepared materials were characterized by FT-IR, SEM, TEM, EDXRF, TGA, elemental analysis, XPS, and magnetic moment determination. In this paper, the adsorption mechanism of the modified and unmodified adsorbents was well discussed. Four kinds of waste water (watermelon juice, expired sprite, sugar-pressing waste water, and confectionary waste water) were employed to produce heavy metal ion adsorbents; the chemical properties of hydrothermal carbon derived from the proposed sources were analyzed as well...

Recent studies have shown the potential of food waste materials as low cost adsorbents for the removal of heavy metals and toxic elements from wastewater. However, the adsorption experiments have been performed in heterogeneous conditions, consequently it is difficult to compare the efficiency of the individual adsorbents. In this study, the adsorption capacities of 12 food waste materials were evaluated by comparing the adsorbents' efficiency for the removal of 23 elements from complex multi-element solutions, maintaining homogeneous experimental conditions...
