Nucleotide binding site leucine-rich repeats (NBS-LRR) accounting for the main disease resistance proteins play an important role in plant defense against pathogen attack. The current study aimed to identify new NBS-LRR gene members in native types of cucurbit species in Iran. Accordingly, DNAs of melon, cucumber and cantaloupe native types to Iran were identified using three primer pairs. PCR ...

Supramolecular capping of cucurbit[5]uril (CB[5]) by gold nanoparticles has been achieved via a facile reduction of an aqueous solution of HAuCl(4) by NaBH(4) in the presence of various amounts of CB[5]. The resultant assemblies were very stable in solution, and were found to form dynamic aggregates consisting of a controllable ratio of singly and doubly capped CB[5].

Biomass - that is a new feather in your cap: palm shell powder was used as support for novel uranyl complexed cucurbit[5]uril oligomer to obtain a selective extractant for uranium. The key to the selectivity lies in the perfect environment of the two portals of cucurbit[5]uril for uranyl ion binding.

Ali, A., Mohammad, O., and Khattab, A. 2012. Distribution of viruses infecting cucurbit crops and isolation of potential new virus-like sequences from weeds in Oklahoma. Plant Dis. 96:243-248. Field surveys were conducted from 2008 to 2010 to detect and determine the incidence of viruses in the major cucurbit-growing areas of Oklahoma. In total, 1,049 symptomatic leaf samples (890 from cucurbit...

The binding properties of the cucurbit[7]uril host with three structurally related ferrocene-containing guests, ferrocenyltrimethylammonium, ferrocenylmethyltrimethylammonium and ferrocenylethyltrimethylammonium, have been investigated using (1)H NMR spectroscopy, mass spectrometry, voltammetry and computational methods. The experimental and computational data indicate that the stability of the...

Crystallochemical analysis methods based on the Voronoi-Dirichlet partition of crystal space are extended to supramolecular complexes of any complexity. The sizes and shapes of receptor cavities and substrate molecules are shown to be successfully estimated as volumes and the second moments of inertia of the corresponding molecular Voronoi-Dirichlet polyhedra. To predict which organic substrate...

The macrocyclic host, cucurbit[8]uril, is used to facilitate cross-linking of colloidal particles and polymers in microdroplets resulting in thermoand photo-responsive supramolecular colloidal microcapsules. Methyl viologen-bearing colloidal particles were prepared using template polymerisation and combined with cucurbit[8]uril and an azobenzene-functionalised polymer within microfluidic drople...

The macrocycle family of molecules called cucurbit[n]urils are potential drug delivery vehicles as they are able to form host-guest complexes with many different classes of drugs. This study aimed to examine the utility of Cucurbit[6]uril (CB[6]) in topical cream-based formulations for either localised treatment or for transdermal delivery. Cucurbit[6]uril was formulated into both buffered crea...

Effect of rootstock on yield and quality cucumber scion was studied at Department Vegetable Science, College Agriculture, Vellayani, Thiruvananthapuram, Kerala during February-May, 2021. Parthenocarpic non-parthenocarpic scions were grafted onto five different cultivated cucurbit species i.e. pumpkin, bottle gourd, oriental pickling melon, culinary melon ash gourd. Significant variations observ...
