We have isolated a clonal line reversed (rev) of homozygous Japanese flounder through gynogenesis. The homozygous offspring gynogenetically produced from rev exhibited reversal of organization of the metamorphic L/R asymmetry such as the direction of eye-migration at a high frequency (20-30%). The molecular analysis using a left-specific marker pitx2 revealed that the embryonic L/R axis was amb...
A small, fast-breeding, diploid relative of the frog Xenopus laevis, Xenopus tropicalis, has recently been adopted for research in developmental genetics and functional genomics. X. tropicalis shares advantages of X. laevis as a classic embryologic system, but its simpler genome and shorter generation time make it more convenient for multigenerational genetic, genomic, and transgenic approaches...
The great economic importance of sugar beet determines the ongoing biotechnological studies conducted worldwide to improve technology obtaining doubled haploids (DHs) using method unpollinated ovule culture in vitro. To induction gynogenesis, we tested effect thidiazuron (TDZ), temperature bud pretreatment, different concentrations sucrose, and culturing on liquid or solid medium. Three genotyp...
