Bananas and plantains are an important source of food and income for millions of persons in the world. Their production is constrained by many biotic and abiotic stress factors but their improvement through traditional plant breeding methods is very difficult because they do not produce seeds, are polyploid and have a long generation time. Biotechnological approaches like genetic transformation...
Variation of transgene expression caused by either position effect at the insertion site or the promoter/enhancer elements employed for the expression of selectable marker genes has complicated phenotype characterization and caused misinterpretation. We have developed a reporter system in rice to analyze the influence of vector configuration, spacer and selectable marker gene promoter on the ex...
ABSTRACT- In order to produce transgenic rice lines lacking selectable marker gene, biolistic co-transformation technique using gold nanoparticles was adopted. In the first step, the efficiency of different sizes of gold particles was evaluated. The results showed that the efficiency of the nanoparticles in the transformation was comparable to that of the micro particles. Subsequently, two sepa...
Experimental genetics have been widely used to explore the biology of the malaria parasites. The rodent parasites Plasmodium berghei and less frequently P. yoelii are commonly utilised, as their complete life cycle can be reproduced in the laboratory and because they are genetically tractable via homologous recombination. However, due to the limited number of drug-selectable markers, multiple m...
