Production, optimization and characterization of silver oxide nanoparticles using Artocarpus heterophyllus rind extract and their antifungal activity

For the first time, the phytochemical fabrication of noble silver oxide nanoparticles was reported using Artocarpus heterophyllus rind extract as well as their characterization. The UV-vis absorption spectrum of the phytochemical-mediated reduced reaction mixture showed a surface plasmon peak at 428 nm, which confirmed the presence of silver nanoparticles. The silver nanoparticle production was ideal at pH 9 with 2.0 mL...

Phylogenetic characterization of East African cassava mosaic begomovirus (Geminiviridae) isolated from Manihot carthaginensis subsp. glaziovii (Müll.Arg.) Allem., from a non-cassava growing region in Tanzania

Manihot carthaginensis subsp. glaziovii (Müll.Arg.) Allem., a wild relative of cassava, native to Brazil, is one of the popular agroforestry trees used for hedges and/or boundary plants surrounding homesteads and farms and also harbours cassava mosaic begomoviruses (CMBs) and cassava brown streak ipomoviruses. Sequences of the DNA-A component of East African cassava mosaic virus (EACMV) isolates from M....

Genetic diversity of Cameroonian bread wheat (Triticum aestivum L.) cultivars revealed by microsatellite markers

The assessment of genetic diversity is a key prerequisite for studying the adaptation of populations to new environmental conditions, and therefore for the selection of new varieties. The present investigation aimed to estimate the levels and genetic structure within bread wheat varieties grown in Cameroon. Thus, genetic diversity was assessed in 17 hexaploid wheat cultivars, using 11 microsatellite markers. Genetic...

Expression and functional evaluation of Mytilus galloprovincialis foot protein type 5 (Mgfp-5), the recombinant mussel adhesive protein

Mussel contains a variety of adhesion proteins, among which, Mytilus galloprovincialis foot protein type 5 (Mgfp-5) is one of the major proteins required for substrate adhesion. The labor-intensive nature and insufficiency of the extraction process have frequently resulted in very little purified recombinant Mgfp-5. These prompt technologies such as chemical synthesis and genetic engineering are employed to overcome...
