Genetic diversity among some productive genotypes of tomato (Lycopersicon esculentum Mill.)

This research was done at Vegetable Experimental Farm, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology, Jammu during spring and summer seasons, 2007-2009. D2-statistics revealed that β-carotene contributed maximally towards the genetic divergence followed by ascorbic acid, total soluble solids, alcohol insoluble solids, pericarp thickness, lycopene content and...

Production of friable embryogenic callus and regeneration of Ugandan farmer-preferred cassava genotypes

Generation of embryogenic callus is a key step in genetic engineering of many crop species, including cassava. Protocols for generation of friable embryogenic callus (FEC) have been lacking for Ugandan cassava genotypes, thereby delaying their genetic engineering for agronomic and other desirable traits. The objective of this study was to determine conditions suitable for production and regeneration of FEC in the...

Dihydrotestostenone increase the gene expression of androgen receptor coregulator FHL2 in human non-transformed epithelial prostatic cells

The actions of androgens are mediated through an androgen receptor (AR), and AR activity is modulated by coregulators. The aim of this study was to assess the action of androgens in the expression of AR and the coregulators FHL-2 and SHP-1 in human non-transformed epithelial prostatic cells (HNTEP) treated with androgens. Prostate tissues were obtained from 12 patients between 60 and 77 years of age. HNTEP cells were...

Effects of rumen digesta on the physico-chemical properties of soils in Nsukka, Southeastern Nigeria

In tropical and subtropical areas, the importance of organic manure in improving soil physico-chemical properties and crop production for food security cannot be overemphasized. A study was conducted to investigate the effects of rumen digesta on the physical and chemical properties of soils in Nsukka, Enugu State, Nigeria. The soil samples collected from Opi, Nsukka were treated with four rates of rumen digesta (viz....

Estimation of heritability and genetic gain in height growth in Ceiba pentandra

Ceiba pentandra (L.) has been selected for plantation establishment in Ghana under the National Forest Plantation Development Programme of Ghana (NFPDP). This has led to a rise in demand for its seedlings for large scale commercial plantation establishments with seed of C. pentandra being collected from the wild and used to raise seedlings to meet the demands of the programme. The primary purpose of most of these...

Evaluation of genetic diversity in barley (Hordeum vulgare L.) from Wollo high land areas using agro-morphological traits and hordein

This study aimed to determine the genetic diversity and relationships among barley varieties (Hordeum vulgare L.) growing at Wollo Highland areas by using hordein and agro-morphological traits. Twenty (20) varieties were laid down in randomized complete block design (RCBD) design with three replications; they were planted by irrigation at Wollo University, Dessie Campus from January to May 2014. The genetic analysis...

Purification and characterization of a new cold active lipase, EnL A from Emericella nidulans NFCCI 3643

A mesophilic fungi producing an extracellular cold-active lipase was isolated from the soil samples of palm oil mill effluent dump sites, Pedavegi, West Godavari Dist, A.P. India and was identified as Emericella nidulans. The enzyme was purified by ammonium sulfate fractionation followed by hydrophobic interaction chromatography using phenyl sepharose. The enzyme was 35 fold pure compared to crude with a specific...

Evaluation of methane production features and kinetics of Bougainvillea spectabilis Willd waste under mesophilic conditions

The objective of this study was to investigate and evaluate the biomethane potential (BMP) of Bougainvillea spectabilis Willd waste in Yunnan, China, when subjected to mesophilic anaerobic digestion (AD). Three different categories of plant waste investigated were as follows: the flowers, leaves and stems of B. spectabilia. These three portions were assessed for their BMP in a laboratory-scale batch anaerobic digester...
