Generation and Developmental Characteristics of Porcine Tetraploid Embryos and Tetraploid/diploid Chimeric Embryos
The aim of this study was to optimize electrofusion conditions for generating porcine tetraploid (4n) embryos and produce tetraploid/diploid (4n/2n) chimeric embryos. Different electric field intensities were tested and 2 direct current (DC) pulses of 0.9 kV/cm for 30 μs was selected as the optimum condition for electrofusion of 2-cell embryos to produce 4n embryos. The fusion rate of 2-cell em...
متن کاملHybridization and reproductive isolation between diploid Erythronium mesochoreum and its tetraploid congener E. albidum (Liliaceae).
Polyploidy has played an important role in angiosperm diversification, but how polyploidy contributes to reproductive isolation remains poorly understood. Most work has focused on postzygotic reproductive barriers, and the influence of ploidy differences on prezygotic barriers is understudied. To address these gaps, we quantified hybrid occurrence, interspecific self-compatibility differences, ...
متن کاملHeterochronic development of the floret meristem determines grain number per spikelet in diploid, tetraploid and hexaploid wheats.
BACKGROUND AND AIMS The inflorescence of grass species such as wheat, rice and maize consists of a unique reproductive structure called the spikelet, which is comprised of one, a few, or several florets (individual flowers). When reproductive growth is initiated, the inflorescence meristem differentiates a spikelet meristem as a lateral branch; the spikelet meristem then produces a floret meris...
متن کاملIdentification and Characterization of Diploid and Tetraploid in Platycodon grandiflorum.
Platycodon grandiflorum (PG), a species of herbaceous flowering perennial plant of the family Campanulaceae, has been used as a traditional oriental medicine for bronchitis, asthma, pulmonary tuberculosis, diabetes, hepatic fibrosis, bone disorders and many others similar diseases and as a food supplement. For the primary profiling of PG gas chromatography coupled with high resolution - time of...
متن کاملRelation between Carotenoid Content and Number of Genes per Cell in Diploid and Tetraploid Corn^
The evaluation of induced chromosome doubling as a method of plant breeding requires more information on the specific effects of chromosome doubling than is available at the present time. It is important that this information be procured from comparisons of related diploid and tetraploid strains of known origin and similar genetic constitution, Such strains have not been generally available bec...
