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 Sex has a significant effect on various traits among dioecious plants. In this analysis of the sex radial growth and wood density numerous 20-year-old trees Populus deltoides growing in common garden, male performed better than females growth, but did not significantly affect density. Growth rate were weakly negatively correlated. selection is also critical for controlling seed-hair po...
seedlessness is the most important trait in table grape and raisin industry which has attracted breeders from long ago. breeding grapes by traditional methods result in low number of seedless progenies and their selection requires long time. therefore, marker-assisted selection (mas) can overcome the selection difficulty and would decrease high cost of progeny maintenance for several years. in ...
Improvement of quality protein maize (QPM) along with high content of lysine and tryptophan had foremost importance in maize breeding program. The efficient and easiest way of developing QPM hybrids was by backcross breeding in marker aided selection. Hence, the present investigation aimed at conversion of elite maize inbred line BML-7 into QPM line. CML-186 was identified to be a donor variety...
Marker-free transgenic plants can be developed through transposon-mediated transgene reintegration, which allows intact transgene insertion with defined boundaries and requires only a few primary transformants. In this study, we improved the selection strategy and validated that the maize (Zea mays) Activator/Dissociation (Ds) transposable element can be routinely used to generate marker-free t...
Rice hoja blanca (white leaf) disease can cause severe yield losses in rice in the Americas. The disease is caused by the rice hoja blanca virus (RHBV), which is transmitted by the planthopper vector Tagosodes orizicolus. Because classical breeding schemes for this disease rely on expensive, time-consuming screenings, there is a need for alternatives such as marker-aided selection. The varietie...
In this paper test selection strategies in formal conformance testing are considered. As the testing conformance relation we use the ioco relation, and extend the previously presented on-the-fly test generation algorithms for ioco to include test selection heuristic based on a specification coverage metric. The proposed method combines a greedy test selection with randomization to guarantee com...
