Assessing the genetic diversity of 48 groundnut (Arachis hypogaea L.) genotypes in the Guinea savanna agro-ecology of Ghana, using microsatellite-based markers

Groundnut (Arachis hypogaea L.) is the most important grain legume in Ghana. However, its production is constrained by a myriad of biotic and abiotic stresses which necessitate the development and use of superior varieties for increased yield. Germplasm characterisation both at the phenotypic and molecular level is important in all plant breeding programs. The aim of this study was to characterise selected advanced...

Effects of Moringa oleifera leaf extract on morphological and physiological growth of cassava and its efficacy in controlling Zonocerus variegatus

Zonocerus variegatus infestation has been found to cause a lot of devastation in the production of cassava crop plants in tropical and subtropical areas. Understanding the efficacy of Moringa oleifera leaf extract on controlling Z. variegatus is desired. The present study was conducted in the Department of Crop Science experimental site, Faculty of Agriculture, University of Nigeria, Nsukka to investigate the effects of...

Anti-nutrient, vitamin and other phytochemical compositions of old and succulent moringa (Moringa oleifera Lam) leaves as influenced by poultry manure application

The study was carried out to determine the anti-nutrient, vitamin and other phytochemical compositions of old and succulent leaves of Moringa oleifera plants as influenced by poultry manure application. Three levels of poultry manure, that is, 0, 5 and 10 tonnes ha-1 were used for treatment. Poultry manure application insignificantly (p > 0.05) increased oxalate, phytate and saponin compositions of the leaves. The...

Effects of ethylene inhibitors, silver nitrate (AgNO3), cobalt chloride (CoCl2) and aminooxyacetic acid (AOA), on in vitro shoot induction and rooting of banana (Musa acuminata L.)

Significant increase in shoot regeneration, leaf chlorophyll content and rooting occurred when silver nitrate (AgNO3), cobalt chloride (CoCl2) or aminooxyacetic acid (AOA) were added to banana culture medium. The highest numbers of shoots per explants shoot length and leaf surface area was obtained when media were supplemented with 10 mgl-1 AgNO3. Number of shoots per explants increased three fold, shoot length and leaf...

Bacteriocinogenic potential and genotypic characterization of three Enterococcus faecium isolates from Algerian raw milk and traditional butter

The detection of bacteriocinogenic potential of Enterococcus sp. isolates from Algerian raw milk coded LO4 and LO12 and from traditional butter coded BRO2 was carried on M17 buffered medium. PCR amplification of Enterococcus sp. DNA using specific enterococcal primers gave 733 bp fragments. The phylogenetic analysis using the neighbour joining method further supported the identification of the three strains as...

Multiple protein-domain conservation architecture as a non-deterministic confounder of linear B cell epitopes

Epitope prediction is a critical step to diagnostic and vaccine discovery. Despite existence of some parameters for epitope discovery, this area remains inconclusive and wanting-for new complementary or stand-alone tools. The phenomenon of multiple protein-domain conservation architecture (MPDCA) as used here refers to homologous motifs unveiled by multiple sequence alignments across strain-variants of the same protein...
