Aphis gossypii Glover causes direct and indirect damage to Cucumis melo L. crops. To decrease the harmful effects of this pest, one of the most economically and environmentally acceptable options is to use genetically resistant melon varieties. To date, several sources of resistance carrying the Vat gene are used in melon breeding programmes that aim to prevent A. gossypii colonization and the ...

Unlike fungal and bacterial diseases, no direct method is available to control viral diseases. The use of resistance-inducing compounds can be an alternative strategy for plant viruses. Here we studied the basal response of melon to Melon necrotic spot virus (MNSV) and demonstrated the efficacy of hexanoic acid (Hx) priming, which prevents the virus from systemically spreading. We analysed call...

'Forehead to forehead I meet thee, this third time, Moby Dick!' [Ahab (Melville, 1851)] Herman Melville's fictional portrayal of the sinking of the Pequod was inspired by instances in which large sperm whales sank whaling ships by ramming the ships with their heads. Observations of aggression in species of the four major clades of cetacean and the artiodactyl outgroup suggest that head-butting ...

BACKGROUND A critical analysis was made of cucurbit descriptions in Dioscorides' De Materia Medica, Columella's De Re Rustica and Pliny's Historia Naturalis, works on medicine, agriculture and natural science of the 1st century ce, as well as the Mishna and Tosefta, compilations of rabbinic law derived from the same time period together with cucurbit images dating from antiquity including paint...

The major cause of powdery mildew in melons (Cucumis melo L.) is the fungus Sphaerotheca fuliginea. There are several cultivar- and season-specific races of this fungus. In order to control powdery mildew, it is important to introduce resistance to fungal infection into new cultivars during melon breeding. Haploid breeding is a powerful tool for the production of pure lines. In this study, it w...

Introduction: The genetic diversity of melon groups has been characterized using molecular analyses (5, 6, & 8). Random amplified polymorphic DNA markers have been used by García et al. (1) and Staub et al. (7) to assess the genetic diversity of elite germplasm. Likewise, Mliki et al. (3) and Nakata (4) used the same markers employed by Staub et al. (7) to define the diversity among African and...

Resistance breakdown has been observed following the deployment of plant cultivars resistant to pests. Assessing the durability of a resistance requires long-term experiments at least at a regional scale. We collected such data for melon resistance conferred by the Vat gene cluster to melon aphids. We examined landscape-level populations of Aphis gossypii collected in 2004-2015, from melon-prod...

In this study, goat fat (Capra hircus) and melon oil were extracted and used to formulate self-nanoemulsifying drug delivery systems (SNEDDS) based on either goat fat alone or its admixture with melon oil by employing escalating ratios of oil(s), surfactant blend (1 : 1 Tween 60 and Tween 80), and cosurfactant (Span 85), with or without carbosil, a glidant, for the delivery of indomethacin. The...

While compiling genetic linkage maps in several plant species based upon restriction fragment length polymorphisms (RFLPs), it was noted that the incidence of polymorphism differs among species. The basis of this disparity was investigated in this study by examining the nucleotide sequence at homologous loci among distinct cultivars within two species which exhibit considerably different levels...

Anticoagulants are drugs used to inhibit the development and enlargement of a blood clot. Melon is known contain adenosime that function stop clotting cell chip. This study aims identify secondary metabolites contained in melon juice, fruit juice anticoagulant activity vivo melon, look for an effective dose as potential compared with aspirin. A total 15 male mice were divided into 5 groups, i.e...
