Apomixis or asexual seed formation represents a potentially important agronomic trait whose introduction into crop plants could be an effective way to fix and perpetuate desirable genotype through successive generations. However, the gene regulatory pathways underlying apomixis remain unknown. In particular, potential function of microRNAs, which are known play crucial roles in many aspects plant growth development, remains determined with regards switch from sexual apomictic...
Apomixis, a natural form of asexual seed production in plants, is considered to have great biotechnological potential for agriculture. It has been hypothesised that de-regulation the sexual developmental pathway could trigger apomictic reproduction. The genus Boechera represents an interesting model system understanding apomixis, having both and genotypes at diploid level. Quantitative qRT-PCR most extensively used method validating genome-wide gene expression analyses, but order obtain...
Apomixis refers to plant asexual reproduction through seeds that give rise progeny which are genotypically identical the maternal parent. It has evolved from many different sexual taxa although underlying genetic factors remain unknown. Previous analyses of over-representation transcription factors, in a comparison microdissected ovules apomictic and Boechera, showed factor mRNAs possessed microRNA (miRNAs) binding sites, thus pointing miRNAs as potentially important may be involved...
Rather erroneously, eggs consumption is linked to increase in plasma cholesterol content and incidents of cardiovascular diseases, cancer, stroke, or diabetes. This misconception which more pervasive particularly sub-Saharan Africa, has led very low patronage intake. In this study, egg patterns, desired characteristics, the extent perception as a health risk entrenched among consumers Volta Region Ghana, were examined.The study used primary data for analysis 2-stage sampling technique was...
The cowpea variety Videza, which was used as the control, matures early (70 days after planting), although it produces low yields. Gamma irradiation mutagenesis to induce Videza into extra-early maturing and higher yielding mutant genotypes. A single seed descend population developed for radio-sensitivity test, a Lethal Dose 50 (LD50) of 240.5 Gy determined, applied from cobalt-60 (60Co) source, acutely mass irradiate 1800 seeds, at Ghana Atomic Energy Commission. irradiated seeds (M1) were...
Vitamin A deficiency poses serious health concerns among the Ghanaian populace, particularly children and pregnant women. The production consumption of yellow maize, which contains pro-vitamin carotenoids such as beta carotene, is therefore encouraged. Consequently, maize fast gaining acceptance. However, in near future comensurate increases must be achieved to ensure food security. In this regard, aims study were to: evaluate farmer willingness cultivate varieties with enhanced carotene...
The sn-1,2-diacylglycerol kinase homologue gene, dgkA, is a sporulation gene indispensable for the maintenance of spore stability and viability in Bacillus subtilis. After 6 h growth resuspension medium, endospore morphology dgkA mutant by standard phase-contrast microscopy was normal; however, after 9 h, endospores appeared mostly dark microscopy, suggesting defect spores. Moreover, electron microscopic studies revealed an abnormal cortex structure onset sporulation, indication...
As a prerequisite for the breeding of virus-resistant okra cultivars, effect Okra mosaic virus infection on physiological performance ten cultivars were assessed under field conditions within coastal savannah agro-ecological zone Ghana.All succumbed to disease and expressed varying degrees symptoms.The results showed that plant height at initial 50% flowering significantly reduced with cultivar Clemson spineless showing highest reduction 38% 35% respectively.Plant podding was also in all...
Groundnut (Arachis hypogaea L.) production is threatened by the advent of many emerging pests and diseases, key among them being ringspot virus (GRSV). The numerous alternative host crops make its control particularly difficult, resulting in heightened transmission risk increased yield loss. mechanisms underlying loss, though not fully understood, have often been speculated to be a result reduction photosynthesis transpiration infected leaves. This study was therefore aimed at testing effect...
Purpose: Genetic makers are indispensable in the genetic quantification and characterization of plant species which rubber tree is no exception. Markers have been used severally identification diversity analysis species. However, Ghana relatedness among introduced limited. The study aimed to use microsatellite markers assess variability evaluate relationships clones Hevea brasiliensis cultivated Ghana.Research Method: Genomic DNA was extracted from fresh leaves following Cetyltrimethyl...
The cowpea beetle Callosobruchus maculatus (Fab.) is a major insect pest of stored in Ghana. efficacy coconut, groundnut and soybean oils applied at 1, 2, 5 10 ml kg-1 pirimiphos-methyl 2.5, 5.0 active ingredient 2 water grain (1/16, 1/8 1/4 the recommended dose) alone or combination to adults immature stages C. persistence treatments were evaluated laboratory. All caused significant mortality compared untreated controls. Lower dosages when combined highly toxic maculatus. mixtures also...
Six generations of eggplants (P1, P2, F1, F2, BC1 and BC2) obtained from two crosses SM001-07 x ST004-03 San005-01 were grown in an open field using Randomized complete Block Design with four replications. The experiment was conducted to determine gene effects for the inheritance twelve nutritional antioxidant traits eggplant generation mean analysis. analysis variance showed significant differences most indicating presence sufficient variation materials under study. Additive-dominance...
