Genetic variability in coat protein gene of sugarcane mosaic virus in Pakistan and its relationship to other strains
Sugarcane mosaic virus (SCMV) is one of the three causative viruses of mosaic in sugarcane, a sugar crop widely grown under tropical and subtropical conditions worldwide. Although molecular characterization of SCMV strains was reported from many countries, strain occurring in Pakistan, a major sugarcane producer has not been reported so far. One hundred and two (102) sugarcane samples from foremost sugarcane growing...

Effect of exogenous phytohormones and sucrose on micropropagation and microtuberisation of Manihot esculenta Crantz var. TMS 96/0023
The effect of exogenous phytohormones and sucrose on micropropagation and microtuberization from nodal cuttings of Manihot esculenta was studied. Direct and indirect organogeneses were established from these explants. When nodal cuttings were cultured in the presence of 0.01 to 0.1 mg.L-1 of BAP or NAA there was induction of the budding of axillary buds, with the highest percentages of nodal cuttings with axillaries...

Microbial and heavy metal contamination of pineapple products processed by small and medium scale processing enterprises in Rwanda
Fruit products are increasingly consumed but highly prone to microbial deterioration if not adequately processed and stored. The present study was conducted to evaluate the microbial and heavy metal concentrations of packed pineapple nectars, syrups and jams processed by 10 Small and Medium scale pineapple processing Enterprises (SMEs) over a storage duration of 12 months. Collected samples were analysed to determine...

Evaluation of genotoxicity of profenofos to freshwater fish Channa punctatus (Bloch) using the micronucleus assay
The present study investigates the genotoxicity of profenofos (PFF), an organophosphate pesticide in erythrocyte cells of freshwater fish, Channa punctata (Bloch) using micronucleus assay. The 96 h LC50 value of PFF (50% EC) was estimated for the fish species in a semistatic system and then 50% of LC50 was determined as 1.15 ppb. The fish specimens were exposed to 1.15 ppb sublethal concentration of the pesticide and...

Nigerian mistletoe (Loranthus micranthus Linn) aqueous leaves extract modulates some cardiovascular disease risk factors in monosodium glutamate induced metabolic dysfunction
The safety of monosodium glutamates (MSG's) usage has generated much controversy locally and globally. This study investigates the efficacy of Loranthus micranthus in modulating the metabolic disorder associated with MSG intake. Thirty five (35) female rats randomized to three groups labeled 1 (7 rats), 2 (21 rats) and 3 (7 rats), respectively were used. They were administered with normal saline, MSG (200 mg/Kg) and...
