Distorted genetic segregation of the transposon mPing at the long arm of chromosome 12 in rice
A class II transposable element, mPing exists in the rice genome ubiquitously and can transpose even in ordinary cultivation conditions. A copy of mPing was identified at the long arm of chromosome 12. In reciprocal backcrossed F1s between a heterozygote and a homozygote without mPing, the male gametes with this mPing from heterozygotes were transmitted to the next generation at a lower frequen...
متن کاملmPing: The bursting transposon
Though transposable elements (TEs) have been considered as an efficient source of evolution, it has never been possible to test this hypothesis because most of TE insertions had occurred millions of years ago, or because currently active TEs have very few copies in a host genome. However, mPing, the first active DNA transposon in rice, was revealed to hold a key to answer this question. mPing h...
متن کاملHigh Potential of a Transposon mPing as a Marker System in japonica × japonica Cross in Rice
Although quantitative traits loci (QTL) analysis has been widely performed to isolate agronomically important genes, it has been difficult to obtain molecular markers between individuals with similar phenotypes (assortative mating). Recently, the miniature inverted-repeat transposable element mPing was shown to be active in the japonica strain Gimbozu EG4 where it had accumulated more than 1000...
متن کاملEarly Embryogenesis-Specific Expression of the Rice Transposon Ping Enhances Amplification of the MITE mPing
Miniature inverted-repeat transposable elements (MITEs) are numerically predominant transposable elements in the rice genome, and their activities have influenced the evolution of genes. Very little is known about how MITEs can rapidly amplify to thousands in the genome. The rice MITE mPing is quiescent in most cultivars under natural growth conditions, although it is activated by various stres...
متن کاملTwo dominant mutations in the mouse fused gene are the result of transposon insertions.
The mouse Fused locus encodes a protein that has been implicated in the regulation of embryonic axis formation. The protein, which has been named Axin to distinguish it from the product of the unrelated Drosophila melanogaster gene fused, contains regions of similarity to the RGS (regulators of G-protein signaling) family of proteins as well as to dishevelled, a protein that acts downstream of ...
