Molecular genetic approaches to studying fertilization in model systems
2004
Reproduction
In a wide range of experimental systems, a variety of both forward and reverse genetic approaches are becoming available for the study of the molecules involved in fertilization. ...
We highlight some of the recent advances resulting from these genetic methods and their applications in these systems. ...
One of the first instances of the use of a genetic model system to study fertilization was with t-haplotype mice. ...

Stabilization of microsatellite sequences by variant repeats in the yeast Saccharomyces cerevisiae
1997
Genetics
We examined the effect of a single variant repeat on the stability of a 51-base pair (bp) microsatellite (poly GT). ...
The stabilizing effect of the variant base was also observed in strains with mutations in the DNA mismatch repair genes pms1, msh2 and msh3, indicating that this effect does not require a functional DNA ...
In this article we reinvestigate the effects of variant repeats on the stability of the poly GT microsatellite. ...

Genetic Divergence of Bradyrhizobium Strains Nodulating Soybeans as Revealed by Multilocus Sequence Analysis of Genes Inside and Outside the Symbiosis Island
2014
Applied and Environmental Microbiology
The gene flow level of island genes among genospecies is discussed in the context of the divergence level of off-island genes. ...
However, seven genes inside the symbiosis island ("island" genes;nifA,nifH,nodC,nodV,fixA,trpD, andrhcC2) showed contrasting lower levels of nucleotide diversity and recombination rates than did off-island ...
