Melatonin Preserves the Postharvest Quality of Cut Roses through Enhancing the Antioxidant System.

The vase life of cut rose is relatively short, therefore; preserving its postharvest quality via eco-friendly approaches is of particular economic importance. From the previous literature, despite melatonin (MT) plays diverse important roles in the postharvest quality maintenance, its impact on preserving the postharvest quality of cut flowers is really scarce. This research therefore was undertaken to find out the possibility of exogenous MT as an eco-friendly preservative to extend the vase life of cut roses.

Biological Efficacy of Compounds from Stingless Honey and Sting Honey against Two Pathogenic Bacteria: An In Vitro and In Silico Study.

Honey inhibits bacterial growth due to the high sugar concentration, hydrogen peroxide generation, and proteinaceous compounds present in it. In this study, the antibacterial activity of stingless and sting honey against foodborne pathogenic bacteria isolated from spoiled milk samples was examined. The isolated bacterial strains were confirmed as and through morphological, biochemical, and 16 s RNA analysis.

Identification and Characterization of a New Type of Holin-Endolysin Lysis Cassette in Phage AP1.

Phages utilize lysis systems to allow the release of newly assembled viral particles that kill the bacterial host. This is also the case for phage AP1, which infects the rice pathogen . However, how lysis occurs on a molecular level is currently unknown.

Four concentrations (1, 5, 10, and 15% in acetone solvent) of each EO were tested. The 5, 10, and 15% concentrations of EO had a high repellency effect against compared with , , , , , , and after 30 min of exposure.

Combination of Strobilurin and Triazole Chemicals for the Management of Blast Disease in Mushk Budji -Aromatic Rice.

Rice blast is considered one of the most important fungal diseases of rice. Although diseases can be managed by using resistant cultivars, the blast pathogen has successfully overcome the single gene resistance in a short period and rendered several varieties susceptible to blast which were otherwise intended to be resistant. As such, chemical control is still the most efficient method of disease control for reducing the losses caused due to diseases.

Molecular characterization of isolated from milk samples with regard to virulence factors and antibiotic resistance.

Background And Aim: Raw milk is considered an essential source of nutrition during all stages of human life because it offers a valuable supply of protein and minerals. Importantly, milk is considered a good media for the growth and contamination of many pathogenic bacteria, especially food-borne pathogens such as . Thus, the objective of this study was to characterize and detect its virulence factors and antibiotic resistance from raw milk samples.

Assessing the Capability of Chemical Ameliorants to Reduce the Bioavailability of Heavy Metals in Bulk Fly Ash Contaminated Soil.

In-situ rehabilitation of fly ash at dumping sites has rarely been addressed for crop production due to growth-related constraints, largely of heavy metal (HM) contamination in soils and crops. Current communication deals with a novel approach to identify a suitable management option for rejuvenating the contaminated soils. In this background, a 60-days incubation experiment was conducted with different fly ash-soil mixtures (50 + 50%, A1; 75 + 25%, A2; 100 + 0%, A3) along with four ameliorants, namely, lime (T1), sodium sulphide (T2), di-ammonium phosphate (T3), and humic acid (T4) at 30 ± 2 °C to assess the ability of different fly ash-soil-ameliorant mixtures in reducing bio-availability of HMs.

Phylogeny and pathogenicity of Fusarium solani species complex (FSSC) associated with potato tubers.

Potato (Solanum tuberosum L.) is one of the known five crops cultivated throughout the world after corn, barley, cereals, rice, and wheat, due to its content of high carbohydrates. In developing countries, potatoes are especially had valuable contents as a rich source of starch, vitamins C and B6, and essential amino acids.

Growth, Yield, and Bunch Quality of "Superior Seedless" Vines Grown on Different Rootstocks Change in Response to Salt Stress.

The growth and quality of vines are negatively affected by soil salinity if enough salts accumulate in the root zone. As part of the current study, we estimated the remediating effects of rootstocks under salinity. For this reason, "superior seedless" vines were grafted onto three different rootstocks, such as SO, 1103 Paulson, and own-root ("superior seedless" with their own-root).

Intra- and inter-breed variation in immune response to acute and sub-chronic Salmonella infection and commercial immune-stimulant in two-layer breeds.

Salmonella is one of the most hazardous diseases in poultry farms. Markedly, the application of active immunostimulants is illustrated as potential protective agents against infection in poultry farms. Thus, this work aimed to explore inter- and intra-breed variation in response to acute and subchronic Salmonella enteritidis infection in two-layer breeds (one commercial [Hy-line strain] and another native [Fayoumi breed]).

Molecular Identification of Penicillium sp. Isolated from Citrus Fruits.

Penicillium is one of the most important postharvest pathogens of citrus fruits worldwide. It induces blue or green mold disease, a decay that can lead to significant economic losses during storage. Based on internal transcribed spacer (ITS) sequences, seven Penicillium species and one closely related Talaromyces variabilis were identified from 30 rotten samples of citrus fruits marketed in Qena.

Molecular characterisation of rabies virus detected in livestock animals in the southern part of Egypt during 2018 and 2019.

Brain samples were collected from 33 animals of different species, including buffalo, cattle, dog, donkey, fox and wolf, that had been suspected to be infected by rabies virus (RABV) in different geographical regions of Aswan and Luxor governorates in Egypt. The samples were submitted for histopathological examination and the presence of the nucleic acid and antigens of RABV was tested by RT-PCR and indirect fluorescent antibody technique (IFAT), respectively. Sixteen samples were found positive by all the three examinations.
